abstract = {K0.5Na0.5NbO3 (KNN) based ceramics are considered optimal candidates to replace the toxic Pb-based piezoelectric materials; nonetheless, they are quite difficult to process. Therefore, obtaining an efficient glass-ceramic (GC) will have several advantages in lead-free piezoelectric production. The first step to developing advantageous functional GCs is to determine an adequate glass matrix and the network connectivity of the different structural entities depending on the bulk chemistry. Here, we investigated the structural variations occurring in aluminosilicate systems having Na2O/Al2O3 molar ratios from 1 to 5.7 upon the addition of KNN (0.4 up to 30 mol%) to understand how the bulk composition influences KNN incorporation and the properties of the glasses. Our study shows that more depolymerized aluminosilicate systems incorporate a larger amount of KNN because the Nb structural environment's evolution strongly depends on glass polymerization and the availability of charge compensator ions. No strong crosslinking between [SiO4], [AlO4], and [NbO6] structural entities was found, and there is an evolution from a heterogeneous environment with isolated [NbO6] units having different degrees of distortion to Nb–O–Nb linkages, up to the formation of clusters composed of corner-shared slightly distorted [NbO6]. All glass series tend to move toward these 3D clusters whenever the starting structure includes different entities or a more homogeneous environment. The evolution of the different niobate entities marks the changes in the properties that show non-linear variations with KNN content. Furthermore, the glass chemistry influences the crystallization kinetics, with activation energies for crystallization that vary from ∼300 ± 10 kJ/mol to ∼220 ± 10 kJ/mol depending on the alkali/Al2O3 molar ratios. The developed niobo-aluminosilicate glasses show high refractive indices, high transparency in the visible– NIR region and intense UV absorption. Therefore, these glasses are excellent candidates for photonic applications and optoelectronic devices. The stabilization of a perovskite-like phase upon crystallization confirms the potentiality for use as electro-optical glass-ceramics.},

These dynamics have a high impact on the shape and the thermodynamic properties of the molten zone as well as the plasma. In this work we analyze the local distribution of laser absorption in the melt by shockwave observation and the evolution of the subsequent pressure wave generated during the process. The pressure waves were observed using a pump-probe setup with a high-speed video camera. Furthermore we show a dramatic decrease of pressure waves propagation velocity inside the molten zone as an explicit indicator of the fluid state of the molten zone.},

abstract = {Glass formers exhibit a viscoelastic behavior: at the laboratory time scale, they behave like (glassy) solids at low temperatures and like liquids at high temperatures. Based on this observation, elastic models relate the long time supercooled dynamics to short time elastic properties of the supercooled liquid. In the present work, we assess the validity of elastic models for the shear viscosity and the alpha-relaxation time of supercooled water, using molecular dynamics simulations with the TIP4P/2005f force field over a wide range of temperatures. We show that elastic models provide a good description of supercooled water dynamics. For the viscosity, two different regimes are observed and the crossover temperature is found to be close to the one where the Stokes-Einstein relation starts to be violated. Our simulations show that only shear properties are important to characterize the effective flow activation energy. This study calls for experimental determination of the high frequency elastic properties of water at low temperatures. Published by AIP Publishing.},

In particular, we have succeeded in extracting reliable local structural information around Zr from the MD–RMC model. It was found that a significant fraction of edge-sharing structural units was formed around Zr–O and Li–O polyhedra, resulting in a densely packed configuration of O atoms. This configuration was manifested by a very sharp principal peak in the neutron scattering data. Our model suggested that both the Zr and Li ions are incorporated in the glass as distorted ZrO6 octahedra and distorted LiO4 tetrahedra, respectively. These structural features are discussed in terms of the crystallization behavior of this material.},

In vitro tests with human osteoblast-like cells on substrates with a 45S5 BG coating demonstrated high cell activity on the surfaces. All tested materials exhibited high in vitro biocompatibility as no inhibition in cell proliferation could be observed.

Indeed, in silicate and aluminosilicate glasses the higher amount of Ce4+ does not give rise to UV absorption bands ascribed to CT processes, whereas, in fiber preforms, Ce3+ species can induce the trapping of hole centers, and enhance the photoluminescence efficiency. More generally, these results enhance our understanding of REE structural and chemical roles in amorphous materials and increase our knowledge for technical applications.},

abstract = {Ascertaining elements oxidation state, coordination, and bonding environment provides an understanding of the parameters controlling the elements structural behavior, and in turn, the possibility of developing novel applications. Cerium doped materials are widely used for technological applications, mainly because of the strong UV absorption and the characteristic short decay time of the intense emission in the UV–Vis ranges. In this study, Ce speciation in different glass systems has been evaluated and related to variations in optical and physical properties, as well as to variations in glass network connectivity. Data obtained from X-ray Absorption Spectroscopy, Raman, and Photoluminescence Spectroscopy are presented. By using a multispectroscopy approach, we determined the Ce3+/Ce4+ redox ratio in silicate glasses/melts and the influence of the two different Ce species on structure and properties. Our study indicates that reduced Ce species are favored with an increase in the degree of melt polymerization but hindered in alkaline-rich bulk chemistries. Consequently, the oxygen ion activity (here represented by the theoretical optical basicity) might be used to estimate the Ce redox ratio's evolution. On the contrary, we show that glass luminescence properties cannot be tailored by merely adjusting the bulk chemistry. Furthermore, we propose an alternative approach for detecting and quantifying the different Ce species in glasses, and we show the occurrence of a non-symmetric Raman vibration at ~880 cm−1, whose intensity is well correlated with the Ce3+/Ce4+ redox ratio. We assign this band to the interaction of the SiO4 tetrahedra with Ce4+-O polyhedral. Thus, cerium preferentially links to the silicate network, and we examined the possibility of using Raman spectroscopy to detect and quantify the different Ce species.},

The LSI process offers the possibility to circumvent high temperatures and pressures used in traditional fabrication. Pastes with high solid loading and necessary carbon content are used in order to combine the robocasting with the subsequent LSI process. The influence of the paste rheology on the sample fabrication of multimaterial core–shell structures of reaction-bonded carbides is investigated. The key rheological data, such as the viscosities of the combined pastes, are correlated with the observations from the microstructural investigation using scanning electron microscopy. A correlation between the difference in viscosity and the core geometry can be established. Crack formation in the material combination of RBSC and RBBC is found and compared with layered multimaterial structures of reaction-bonded carbides.

abstract = {Glass is a fascinating material, not only because of its transparency and for its formability, but also because of the manifold facets of bright colors it can display. Just remember how the colored glasses of cathedral windows made us dream in our childhood, and how much we could quarrel in the schoolyard over a marble or a bead necklace. In this chapter, we will attempt to understand the physical origin of different colors and by what chemical processes, hues, and intensity of colors can be controlled in glasses. However, to do so, we must first understand what a color is, and only then will we be able to discuss how the different active color centers, when incorporated into a vitreous matrix, the glass, can create such a variety of responses toward light. We want to focus especially on the most frequent and, thus, typical causes of glass coloring, that is, the mechanisms of absorption. Examples from many transition metal ions will illustrate how their valence, local structure, or relation to other elements can impact the final glass color. The role of plasmon-resonance, involving metallic nanoparticles will also be described. However, other light effects due to reflection and scattering in the bulk or at the surface of a glass can also induce colors. For example, the iridescence of corroded glasses, which originates from multireflection on an alteration layer, can be exploited as an artistic effect. Light scattering by crystals or phase separation also plays an important role, since it gives us the option to modify the aspect from transparent to opalescent or to opaque. Finally, we will present some color-related functionalization of glasses such as photochromism and electrochromism. Many more details on glass and colors can be found in the literature, e. g., [9.1, 9.2, 9.3].},

abstract = {This paper focuses on the preparation of a new extended set of calibrations of cooling rate (fictive temperature) in fused silica determined by inelastic light scattering and its subsequent use to characterize the local cooling rate distribution in ultra-short pulsed (USP) laser modifications. In order to determine the thermal history (e.g. cooling rate and fictive temperature) of fused silica, high-resolution inelastic light-scattering experiments (Raman and Brillouin spectroscopy) were investigated. Calibrations were performed and compared to the existing literature to quantify structural changes due to a change of fictive temperature. Compared to existing calibrations, this paper provides and extension to lower and higher cooling rates. Using this new set of calibrations, we characterized a USP laser modification in fused silica and calculated the local fictive temperature distribution. An equation relating the fictive temperature (Tf) to cooling rates is given. A maximum cooling rate of 3000 K min-1 in the glass transition region around 1200 °C was deduced from the Raman analysis. The Brillouin observations are sensitive to both the thermal history and the residual stress. By comparing the Raman and Brillouin observations, we extracted the local residual stress distribution with high spatial resolution. For the first time, combined Raman and Brillouin inelastic light scattering experiments show the local distribution of cooling rates and residual stresses (detailed behavior of the glass structure) in the interior and the surrounding of an USP laser modified zone.

Structural and mechanical properties showed non-conventional properties evolution as a function of ZnO content which are managed by the modification of ZnO polyhedra. Before glass transition temperature (Tg), the evolution of the Boson peak (BP) frequencies and the elastic properties are in accordance with the idea of the relaxation of the strains inside the glass; after Tg, their evolution shows the transition toward a viscous liquid. BP and mechanical properties study evidences that as nano-heterogeneous domains size increases at a faster rate, the mechanical properties will decrease at a slower rate. This point will be helpful for choosing appropriate composition for optical fiber shaping.},

abstract = {Evolution of spectroscopic properties of a soda–lime silicate glass with different thermal history and under applied uniaxial stress was investigated using Raman and Brillouin spectroscopies as well as Nd3+ photoluminescence techniques. Samples of soda–lime silicate with a cooling rate from 6 × 10−4 to 650 K/min were prepared either by controlled cooling from the melt using a differential scanning calorimeter or by a conventional annealing procedure. Uniaxial stress effects in a range from 0 to −1.3 GPa were investigated in situ by compression of the glass cylinders. The spectroscopic observations of rearrangements in the network structure were related to the set cooling rates or the applied uniaxial stress to calculate an interrelated set of calibrations. Comparing the results from Raman and Brillouin spectroscopy with Nd3+ photoluminescence analysis, we find a linear dependence that can be used to identify uniaxial stress and cooling rate in any given combination concurrently. The interrelated calibrations and linear dependence models are established and evaluated, and equations relating the change of glass network due to effects of cooling rate or uniaxial stress are given.},

abstract = {During the last few decades, many experimental and numerical studies have tried to understand the special dynamics of water at low temperatures by measuring structural relaxation times or shear viscosity, but their conclusions strongly depended on the chosen observable and on the range of temperatures considered. Moreover, recent work [J. Chem. Phys. 2013, 138, 12A526] showed that viscosity and relaxation times could decouple at low temperature in a model binary mixture, raising questions on their equivalence to study supercooled water. Here we used molecular dynamics simulations with the promising TIP4P/2005f water force field to investigate the behavior of both the shear viscosity and the relaxation times of water in a large range of temperatures, in order to get a consistent picture of the dynamics of supercooled water. We show that the TIP4P/2005f model reproduces accurately the experimental values of both the viscosity and the diffusion coefficient over a very large range of temperatures. Focusing first on the structural relaxation dynamics, we observe a decoupling between the so-called alpha- and beta-relaxation times of water at ca. 350 K, suggesting a supercooled-like dynamics over a very large domain of temperatures. By computing shear viscosity over this domain, we compare the accuracy of several phenomenological laws for low temperature dynamics of water to describe both viscosity and alpha-relaxation time. Unlike what is usually admitted, our tests suggest those quantities are not coupled at low temperatures, and thus should not be considered equivalent. In particular, deviations from the Stokes-Einstein relation appear at lower temperatures for the viscosity than for the alpha-relaxation time. These results open new perspectives to understand the dynamics of supercooled water and show the performance of the TIP4P/2005f force field to characterize it.},

abstract = {Aerosol deposition (AD) is a dynamic loading process that can be envisioned as a shock wave loading, necessitating the consideration of the elastic/plastic response of solid materials. Due to the dynamic nature of this process, however, experimental determination of the local pressures during the deposition process is difficult. This work addresses this by investigating the compression and subsequent structure modification of a silicate glass after room-temperature AD on a silicate glass substrate with Raman spectroscopy. Clear structural changes in the short- and middle-range order of the silicate glass were observed, both as intertetrahedral angle distribution and as ring statistic. Therefore, the AD induced permanent densification of the glass, equivalent, in a hydrostatic approximation, to a minimal pressure of 10.5 ± 1.5 GPa during the film deposition process. Furthermore, the analysis of the Nd3+ photoluminescence of the 4F3/2 − 4I9/2 transition provided complementary information on the glass network modifications occurring during film formation. More than a pure hydrostatic densification, the AD seems to present a very intense shear deformation. This work opens up the perspective of evaluating the mechanical response of film-substrate and of the particles themselves, and provides critical information on the mechanisms responsible for the AD film formation.},

abstract = {Incorporation of therapeutic ions into the structure of bioactive glasses for direct stimulation of cells is a very attractive approach for tissue engineering strategies. Lithium has recently been identified as a biologically active ion which can stimulate osteoblast cell activity. In this study, lithium-containing bioactive glasses (Li-BGs) where Li2O substitutes Na2O in different amounts (2.5, 5 and 10 wt.% Li2O) in 45S5 bioactive glass (BC) were produced and made into 3D scaffolds by the foam replica method. The structural changes that occur after heat treatment, the effect of lithium-content on the bioactivity of the glasses and their lithium ion release profiles were investigated. The results show that the novel Li-BC formulations exhibit the formation of an apatite-like layer on their surface after immersion in SBF for 1 day thus confirming their high surface reactivity, similar to undoped 45S5 BC. XRD results showed that the Li-doped BGs crystallize mainly to combeite (Na2Ca2Si3O9) and silicorhenanite (SiO4(PO4)(2)Ca-5) but also Li6P6O18 and Li3PO4 phases were detected. In terms of lithium ion release, the formulations at 2.5 wt.% and 5 wt.% Li2O content were the only ones to be within the therapeutic range (<83 ppm). (C) 2015 Elsevier B.V. All rights reserved.},

abstract = {While the influence of silicate oxide glass composition on its chemical durability is increasingly known, the contribution of structure only is less well understood, yet is crucial for an accurate description of aqueous alteration mechanisms. The effect of structural disorder can be investigated by varying the thermal history of the glass. Furthermore, the structural changes generated by self-irradiation in nuclear glasses can be compared with those induced by fast quenching. In the context of deep geological disposal of vitreous matrices, it is then challenging to address the structural impact on glass durability. Here, a borosilicate glass, the International Simple Glass, was fiberized to obtain a rapidly quenched sample. The quenching rate and fictive temperature were evaluated from in situ Raman and Brillouin spectroscopies. Multinuclear nuclear magnetic resonance was used to obtain insight into the effect of quenching on the pristine and altered glass structure. Higher bond angle distribution and lower mixing of alkalis were observed in the fast quenched glass. Some of AlO4 groups are then Ca-compensated, while a part of BO4 is transformed into BO3 units. The structural modifications increase the hydrolysis of the silicate network occurring in the forward rate regime at 90 °C by a factor of 1.4–1.8 depending on the pH value. Residual rate regime is similarly affected, more significantly at the beginning of the experiments conducted in silica saturated solutions. These findings prove that the reactivity of glass remains controlled by its structure under the various alteration regimes. The structural changes induced by the rapid quenching of borosilicate glasses and their effects on chemical durability have been studied. Understanding how, and how fast, borosilicate glasses degrade is of great importance because they are often used as containment matrices for the disposal of radioactive waste. However, understanding how glass structure affects durability can be troublesome because both structural and compositional factors must be accounted for and are difficult to deconvolute. Now, a team, led by Frédéric Angeli at the CEA, Marcoule, France, have shown, using various spectroscopic techniques, how the effects of structural disorder can be investigated by varying the thermal history of a glass. The results show that this methodology can be used to investigate radiation damage in nuclear glasses, the effects of which are similar to those of quenching.},

abstract = {Protein adsorption on 45S5 bioactive glass (BG, Bioglass) surfaces influences the biocompatibility of Bioglass and the cellular response to the material. The medium pH greatly affects protein adsorption behavior. However, the influence of pH variation on protein adsorption on Bioglass has not been investigated in detail before, although an acidifying pH has been observed in fractured or injured bone tissues. This study investigates how the medium pH (pH 7, 5, and 2) affects protein (serum albumin) adsorption on Bioglass with or without preconditioning in simulated body fluid (SBF). The results show that Bioglass can adsorb a larger amount of bovine serum albumin (BSA) than bioinert glasses at all tested pHs. The BSA adsorption on Bioglass surfaces is pH-dependent and a larger amount of adsorbed BSA is observed at lower pH (5 and 2). After preconditioning, BSA adsorption is significantly enhanced. However, the trend of pH-dependent adsorption is attenuated. No significant difference in BSA adsorption is observed at different pHs after preconditioning. The results reveal for the first time the influence of medium pH on protein adsorption on Bioglass with or without preconditioning treatment in SBF, which provides useful information for developing Bioglass based biomedical devices that will be in contact with protein-containing physiological fluids during applications.},

abstract = {Na1/2Bi1/2TiO3-based relaxor ferroelectrics are extensively investigated for use in transduction applications because of their relatively large electromechanical properties. Integration of these materials into devices, however, requires better temperature stability in addition to electromechanical properties. This work demonstrates a novel approach to enhance the temperature stability of the long-range ferroelectric order as well as to enhance electromechanical properties in a non-ergodic relaxor 0.93(Na1/2Bi1/2)TiO3-0.07BaTiO3 (NBT-7BT) without changing the chemical composition through, for example, chemical substitutions or second phase particles. The approach involves the room temperature deposition of copper electrodes directly on the relaxor ceramic substrate using the aerosol deposition (AD) method. The collision of solid-state particles with the substrate surface during AD results in large impact and residual stresses, inherent to the AD process, which are shown with piezo-response force microscopy to induce long-range ferroelectric domain ordering in non-ergodic relaxor NBT-7BT. Using Raman spectroscopy, the magnitude and depth profile of the stress-induced transformation are determined. It is demonstrated that deposition-induced stresses significantly increase the temperature stability of the electromechanical properties, where long-range ferroelectric ordering is observed up to 150 °C, which is approximately 41 °C higher than NBT-7BT samples without the AD processed electrode. Moreover, the AD treatment also facilitates ferroelectric domain switching at a lower electric field, enabling maximum polarization at a relatively lower field and an enhancement in the piezoelectric response. It is shown that the deposition-induced stress is responsible for such an enhancement. Importantly, this impact-stress-driven tailoring of electromechanical properties can potentially be utilized for other functional ceramic materials as well, where internal residual stress can result in enhanced functional properties.},

This investigation shows that the europium doped TL glasses prepared under vacuum (Eu3+-doped TL-vac) present low OH− concentration, which increases the transparency in the visible spectral range due to a decrease in TeO4 unity and an increase of the transparency in the mid-infrared spectral region. The luminescence spectra show several emission bands from superior energy levels 5D0, 5D1, 5D2 and 5D3→7FJ (J = from 0 to 4). Time resolved luminescence experiments allow the observation of the energy relaxation and migration among the 5D3→5D1 to 7F0→7F6 and 5D1→5D0 to 7F0→7F3 energy levels due to Eu3+ ions pairs, reported here for the first time. The Judd-Ofelt analysis of the emission spectrum allowed us to determine the phenomenological parameters Ω2 and Ω4, indicating that Eu3+ presents less covalent characteristics, less compactness than in others tellurite glasses, and a quantum efficiency of the 5D0 energy level of 51%. These results indicate that TL-vac glass doped with rare earths can be promising candidates for new optical devices.},

Density fluctuations and intermediate range coherence from X-ray scattering (small-angle X-ray scattering) and diffraction (wide angle X-ray scattering) evidence a maximum in their evolution at the same relaxation time. These extrema confirm the existence of an intermediate transitory disordered state between the two more ordered high and low density amorphous states. We propose that the existence of this transitory state confirms the existence of two mega basins in the energy landscape and therefore an amorphous-amorphous transition. Including older Raman results, we show that this intermediate disorder state implies similar mechanisms at all length scales from a few angstroms to 5 nm.},

Using both broadband excitation and fluorescence line narrowing techniques, the D-5(0) -> F-7(1) emission transition was studied under resonant excitation at different wavelengths within the F-7(0) -> D-5(0) band. In order to explore the local structure of the systems, crystal-field analysis was applied assuming C-2v site symmetry. Moreover, from the emission spectra of glass and glass-ceramic systems, Judd-Ofelt parameters Omega(t) (t= 2, 4) were considered. Transition probability (A), stimulated emission cross-section (sigma), radiative lifetime (tau(R)) and branching ratios (beta) due to the transition D-5(0) -> F-7(J) (J = 1, 2, 3 and 4) of Eu3+ ions were evaluated in different local fields and their relative variations were discussed. The crystallization process, which converted the glass into glass-ceramic, promoted an important enhancement in the quantum efficiency, which was improved from 45% to 60%.},

abstract = {Lithium disilicate glass-ceramics show great potential in the fabrication of anisotropic structures due to their high-strength needle-form crystalline phase subjective to processing-induced alignment. Here we explore this strategy by focusing on the mechanistic aspects of fracture. Through different variations of the fracture toughness test we demonstrate the effect of bulk crystal orientation on fracture energy, toughening mechanisms, crystal size and aspect ratio. Using the anisotropic Poisson's ratio of the Li2Si2O5 crystal phase obtained by Resonant Ultrasound Spectroscopy, we apply the new geometry factor developed by Strobl et al. to provide a more accurate insight into the anisotropic crack propagation behavior in LS2 glass-ceramics. Raman spectra and X-Ray Diffraction patterns are resolved for the Li2Si2O5 phase aligned at plane parallel, anti-plane and random orientations.We show that Li2Si2O5 crystallites oriented perpendicular to the crack growth plane tended to induce large scale crack deflection unless the crack was forced into a straight path, thereby promoting crystallite fracture, increased K-Ic-values and accentuated R-curve behavior. Crystal aspect ratio and residual stresses in the glass have been identified as important influencing factors on crack growth behavior and toughening mechanisms.},

Certain thermal, physical, mechanical, and structural properties have been tested. The DSC curves confirmed the glassy nature as well as the thermal stability of our glasses. The Vickers hardness, modulus of elasticity and Raman spectroscopy were put to the test. The increase in elastic moduli and physical characteristic parameters is associated with an increase in the stiffness and a change in the structural network of the glass system with the addition of NaPO3 content by the forming of a P-O-M bridge (M=P, Sb or W), which increases the network connectivity and contributes to an increase in the glass transition temperature and elasticity modulus. This could be due to the polymerization of the glass network as a result of the high concentration of PO4, which acts as a bridge between them and is confirmed by Raman spectroscopy. To establish the similarity between the theoretical and observed results of elastic moduli and Poisson's ratio in our glasses, Mackenzie's Makishima theory was used. Our system has many colors (yellow, blue, transparent), which are related to an increase (reduction) or decrease (oxidation) in the number of electrons in the atomic system of such materials.},

abstract = {The present study focuses on synthesizing and investigating the structure of Eu3+-doped sodium calcium silicate and calcium alumino silicate glasses under extreme high-pressure conditions. For a thorough understanding of glassy systems in extreme conditions, we conducted in-situ micro-luminescence experiments using a diamond anvil cell, reaching pressures up to 16 GPa. Hydrostatic pressure demonstrated a notable impact on luminescence, attributed to the nephelauxetic effect causing the contraction of central-ion-ligand distances. The band transitions of Eu3+ from the 5D0 to 7F1,2 states revealed pronounced pressure-induced splitting, highlighting the pressure influence on crystal-field properties. The energy shifts for the 5D0 → 7F1 transitions were determined to be 0.14 nmGPa−1 and 0.20 nmGPa−1 for sodium calcium silicate and calcium alumino silicate, respectively. These distinct slope differences indicated a lower structural adaptability of the former glass, resulting in reduced deformability under high-pressure conditions. Furthermore, as pressure increased, the asymmetry ratio of the 5D0 → 7F2/1 transitions decreased, though it consistently maintains levels higher than unity, reflecting the highly asymmetric environment surrounding Eu3+ ions. The estimated elastic limit for both samples was approximately 7 GPa. To assess pressure-induced changes in the local environment, Judd-Ofelt intensity parameters were employed for the calcium alumino silicate glass. The trends observed throughout compression revealed that Ω2 > Ω4 up to 6.8 GPa, while Ω2 < Ω4 for higher pressures, indicating higher covalency between Eu3+ ions and ligands in the elastic domain compared to the plastic domain. The observed increase in Si and Al coordination in the plastic domain was found to play a role in these parameters.},

The progressive addition of cations and the substitution of sodium and calcium by magnesium illuminate the impact of magnesium on the glass structure. The proportion of tri-coordinated boron drastically increased with magnesium addition, demonstrating the poor charge-compensating capabilities of magnesium in tetrahedral boron units. Oxygen-17 NMR showed the formation of mixing sites containing both Na and Mg near nonbridging oxygen sites. Furthermore, a high magnesium content appears to result in the formation of two subnetworks (boron and silicon rich) with different polymerization degrees as well as to promote the formation of high-coordination aluminum sites (Al[V] and Al[VI]). Finally, magnesium coordination ranging from 4 to 6, with a mean value shifting from 5 to 6 along the series, suggests that magnesium might endorse an intermediate role in these glasses.},

abstract = {Inelastic deformation of anomalous glasses manifests in shear flow and densification of the glass network; the deformation behavior during indentation testing is linked strongly to both processes. In this paper, the indentation densification field of fused silica is investigated using depth-resolved Raman spectroscopy and finite element simulations. Through affecting the size of the indent, the normal load and the Raman laser spot size determine the spatial sampling resolution, leading to a certain degree of structural averaging. For appropriate combinations of normal load (indent size) and laser spot diameter, a maximum densification of 18.4% was found at the indent center. The indentation behavior was modeled by extended Drucker-Prager-Cap (DPC) plasticity, assuming a sigmoidal hardening behavior of fused silica with a densification saturation of 21%. This procedure significantly improved the reproduction of the experimental densification field, yielding a maximum densification of 18.2% directly below the indenter tip. The degree of densification was found to be strongly linked to the hydrostatic pressure limit below the indenter in accordance to Johnson's expanding cavity model (J. Mech. Phys. Solids, 18 (1970) 115). Based on the good overlap between FEA and Raman, an alternative way to extract the empirical correlation factor m, which scales structural densification to Raman spectroscopic observations, is obtained. This approach does not require the use of intensive hydrostatic compaction experiments.},

abstract = {Alkali-borosilicate glasses are one of the most used types of glasses with a high technological importance. In order to optimize glasses for diverse applications, an understanding of the correlation between microscopic structure and macroscopic properties is of central interest in materials science. It has been found that the crack initiation in borosilicate glasses can be influenced by changes in network interconnectivity. In the NBS2 borosilicate glass system (74.0SiO2-20.7B2O3-4.3Na2O-1.0Al2O3 in mol%) two subnetworks are present, i.e., a silicate and a borate network. Increasing cooling rates during processing were found to improve glasses crack resistance. Simultaneously, an increase in the network interconnectivity accompanied by an increasing capacity for densification were noticed. Their individual contribution to the mechanic response, however, remained unclear. In the present study the borosilicate glasses were systematically modified by addition of up to 4.0 mol% Al2O3. Changes in the network connectivity as well as the short- and medium-range order were characterized using Raman and NMR spectroscopy. Both the Raman and the 11B NMR results show that four-fold-coordinated boron is converted into three-fold-coordination as the Al2O3 content increases. Additionally, 27Al NMR experiments show that aluminum is dominantly present in four-fold coordination. Aluminum-tetrahedra are thus charge balanced by sodium ions and incorporated into the silicate network. Finally, nanoindentation testing was employed to link the inherent glass structure and its network configuration to the mechanical glass response. It was found that the glass softens with increasing Al2O3 content, which enhances the crack resistance of the borosilicate glass.},

The glass structure was investigated by X-ray absorption near edge structure, far- and medium-infrared, and polarized Raman spectroscopic techniques. The results indicate the incorporation of phosphate into the aluminosilicate network not only as partially depolymerized groups but also as fully polymerized groups charge-balanced by aluminate units in Al-O-P bonds. A new analysis method based on polarized Raman spectra in the bending frequency range indicates a preference of phosphate to reorganize the smallest ring structures. Changes in the glass transition temperature with the increase in phosphate content were found to be consistent with the depolymerization of the network structure shown by spectroscopy. By contrast, increasing the silica content by substituting SiO4for AlO4tetrahedra, while keeping the phosphate content constant, was found to have a negligible effect on network polymerization. Still, the glass transition temperature decreased and correlated with a far-infrared sodium band shift to higher frequency. This was interpreted as local changes in bond strength caused by complex interactions between the different network formers and sodium ions.},

abstract = {V2O5 was introduced up to 9 wt.% in a peralkaline alkaline earth aluminosilicate glass and up to 4.8 wt.% in two sodo aluminosilicate glasses, respectively, a peralkaline and a peraluminous one. This introduction had a strong effect on thermal properties, and in particular, on glass transition and crystallization temperatures of the peraluminous glass, which dropped by 89 K, while a moderate drop of similar to 20 K was observed for the two other glasses. Still, the glass stability and the glass-forming ability stayed almost unmodified. The elastic properties measured by Brillouin spectroscopy show a decrease with added Vanadium for the depolymerized alkali earth aluminosilicate and the peraluminous sodo aluminosilicate. In contrast, the elastic properties remained unchanged for the peralkaline composition. Using optical absorption, the proportion of V5+, which is largely dominant, was found to follow the trend predicted using optical basicity considerations. A large photoluminescence emission, centered at similar to 560 nm, was found for all glasses, upon excitation in the UV edge at both similar to 280 and similar to 350 nm. The emission band positions were relatively insensitive to the glass composition, whereas their intensities show variations of one order of magnitude between the sodium peralkaline composition and the calcium depolymerized glass. A too-high concentration of V(2)O(5)shows a quenching effect on the emission. Polarized and cross-polarized Raman spectroscopy allowed us to identify the different environments around the V5+O4 tetrahedra. The highly polarizable V5+O4 tetrahedra associated with two non-bridging oxygens, vibrating at 860 cm(-1), is proposed to be responsible for the more efficient charge transfer. At the opposite end, the formation of VO4-AlO4 units is proposed to quench luminescence properties. Furthermore, we observed that, upon thermal treatment, the optical properties of the glasses are significantly modified without observable structural modifications or evolution of the elastic properties.},

abstract = {External thermal, electrical, and mechanical fields can induce structural phase transitions in lead-free Li-modified Na0.5K0.5NbO3 ferroelectrics, which significantly influence the macroscopic electromechanical response. In particular, the relative stability of the polar monoclinic (or orthorhombic) and tetragonal phases under temperature and stress is critical to realize the ferroelectric and piezoelectric response. In this study, the effect of mechanical and thermal fields on the local structure in the vicinity of the monoclinic-tetragonal (M-T) phase boundary was investigated using a novel in situ combined uniaxial compressive stress- and temperature-dependent Raman spectroscopy experimental arrangement. Experiments were performed up to 300 degrees C and -200 MPa, clearly demonstrating stress-induced M-T phase transition in Li-modified Na0.5K0.5NbO3. A stress-temperature phase diagram has been established based on the change in vibrational modes. It was possible to correlate the relative permittivity singularities previously observed to a given stage of the M-T phase transition using ratio between characteristic Raman band areas. In addition, the measurement method reported here can be applied to other functional ceramics to investigate the influence of mechanical fields on local structure.},

abstract = {In situ micro-Raman spectroscopy was used to investigate the structural evolution of OH--free calcium aluminosilicate glasses, under high pressure and at room temperature. Evaluation was made of the role of the SiO2 concentration in percalcic join systems, for Al/(Al + Si) in the approximate range from 0.9 to 0.2. Under high pressure, the intensity of the main band related to the bending mode of bridging oxygen (nu(B)[T-O-T], where T = Si or Al) decreased gradually, suggesting that the bonds were severely altered or even destroyed. In Si-rich glasses, compression induced a transformation of Qn species to Qn-1. In the case of Al-rich glass, the Al in the smallest Qn units evolved from tetrahedral to higher-coordinated Al ([5] Al and [6] Al). Permanent structural changes were observed in samples recovered from the highest pressure of around 15 GPa and, particularly for Si-rich samples, the recovered structure showed an increase of three-membered rings in the Si/Al tetrahedral network.},

abstract = {XRS measurements at the O K-edge suggest that Si-[5] is formed by 3 GPa. This formation is accompanied by a rapid decrease in the /Si-O-Si and a decrease in Q(0) species. A linear increase in the geometric mean of the high frequency envelope, the chi(b) value, from 999 to 1018 cm(-1) suggests that the conversion of NBO to BO is continuous up to 14 GPa. Above 14 GPa, the Raman spectra show an obvious negative shift in both, the high frequency peak maximum, and the chi(b) position. Simultaneously, the low frequency envelope looses its asymmetry at 14 GPa. This may be explained by either a loss of a vibrational mode in the range 1000-1200 cm(-1) and/or the formation of Si-[6]. The structural evolution of CaMgSi2O6 correlates well with a major change in the compressibility and diffusivity around 5 GPa. (C) 2016 Elsevier Ltd. All rights reserve},

abstract = {OBJECTIVE: Due to past failures of orthopedic 3Y-TZP femoral implants linked to accelerated tetragonal-to-monoclinic phase transformation (t → m), the susceptibility to 'low-temperature degradation' or 'ageing' of 3Y-TZP has been advertised as detrimental to its long-term structural stability. However, no systematic mechanistic experiments on the fatigue resistance of aged 3Y-TZP under cyclic loading can support such statement. In this study, we aim to clarify this issue.
METHODS: Here we evaluate the subcritical crack growth behavior of 3Y-TZP under cyclic loading after 0-50 h of accelerated ageing in an autoclave at 134 °C. The same 3Y-TZP sintered at two different temperatures (1450 °C or 1650 °C) allows for the comparison of materials containing grains with different susceptibilities to transformation. The volume fraction of surface transformed grains was measured using Raman spectroscopy, and the depth of the transformed surface layer from trenches milled with a Focus-Ion Beam. The fracture toughness before and after ageing was determined using the Chevron-notch Beam method. The quasi-static flexural strength was measured in dry conditions and the cyclic lifetime in water at 10 Hz and R-ratio = 0.3 in 4-point-bending at different applied stresses. The fatigue parameter n was derived from 3 different methods, namely SN curves, crack velocity plots and Weibull distributions.
RESULTS: The progression of transformation showed linear kinetics with higher rates for the 3Y-TZP sintered at 1650 °C. Accelerated transformation induced severe crack formation within the transformed layer with parallel orientation to the surface plane, which supposedly behaved as the critical crack size population governing fracture. The stress intensity factor within the transformed layer was increased due to compressive stresses. Consequently, the fatigue parameter n increased consistently from 5 to 50 h of ageing, regardless of the derivation method, suggesting an increased resistance against crack growth during cyclic loading in bending.
SIGNIFICANCE: Our results do not support the long suggested negative clinical implications of LTD regarding mechanical performance, to the contrary, LTD seems to increase the resistance against subcritical crack growth in a humid environment in bending.},

To identify optimum processing windows, melting curves, crystallization kinetics, and pathways for transferring the optimized structures to atmospheric pressure need to be known. Here, we provide melting curves of different polymorphic forms of triolein in the industrially relevant pressure range. The melting points of different polymorphic forms are detected optically in thin samples during stepwise changes of pressure or temperature. For cross-nucleated spherulites, this method allows determining the respective melting points of nuclei and overgrown structures. Tracing the melting curves to atmospheric pressure confirms previous identification of the polymorphic forms at high pressure and enables identifying a previously reported but undefined structure as the β2-form. Employing Raman spectroscopy, it is confirmed that the polymorph remained unaltered during the pressure release. With increasing pressure, the melting curves of the different polymorphic forms approach each other until they successively merge at the highest pressure levels studied.},

The number of O atoms coordinated to two decreased as the amount of Al2O3 is increased, while the opposite happened to O atoms coordinated to three. Al atoms coordinated to four O atoms were reduced as the amount of Al2O3 increases, whereas Al atoms coordinated to five O atoms were increased. Moreover, pair distribution function (PDF) study confirmed that the addition of Al2O3 causes densification of the aluminosilicate samples and, angle distribution function (ADF) corroborated PDF results and explained intermediate and long-range disorder structures of glasses. Assessment of the structural damage under uniaxial tension showed that aluminosilicate glasses are more capable of withstanding deformation without total structural failure than pure silica glasses.},

Its accurate viscosity characterization by micropenetration viscometry or calorimetry is shown to be very challenging in the vicinity of the glass transition, due to the unpreventable occurrence of thermally activated non-stoichiometric crystal nucleation, closely overlapping the relaxation into the liquid state. TiO2 crystal nucleation brings about a compositional modification of the residual melt, with an associated increase in measured viscosity by up to 2 log units. A careful experimental approach and a profound understanding of seed formation are essential to circumvent or at least minimize such inaccuracies, getting as close as possible to the viscosity of the parent homogeneous melt.},

abstract = {In manufacturing reliable glass-ceramics, bulk chemistry and appropriate thermal treatments are critical points. To better understand the influence of nucleation parameters on the crystallisation behaviour and mechanical properties of multicomponent glass-ceramics, we studied the effects of time and temperature on phase stabilisation, the evolution of the crystal phases and physical properties of a Zr-rich lithium-silicate having a SiO2/Li2O molar ratio < 2. Here, we also provide insights into the structural environment of Zr4+ at the early stage of nucleation by Anomalous X-ray Scattering (AXS). By reverse-engineering a commercial material through remelting and sequential thermal treatments, we observed the strong effect of the nucleation temperature on the final mineral assemblage and of the volume fractions of the lithium-disilicate phase on the fracture toughness (KIc). Indeed, the KIc value was increased from ∼0.8 MPa.m½ in the pristine glass up to ∼ 2 MPa.m½, if compared to the original commercial material exhibiting a KIc value of 1.6 MPa.m½. Furthermore, the synthesis of residual glasses at different stages of the thermal treatments allowed us to observe the changes in the glass network structure and properties. AXS was used to extract the contribution exclusively coming from Zr for different nucleation steps. The differential pair distribution functions ΔZrg(r) show two distinct peaks at ∼2.10 Å and 3.44 Å, respectively associated with Zr-O and Zr-Zr/Zr-Si correlations with the formation of edge sharing in addition to corner sharing polyhedra. It was discerned the occurrence of (sub)nano-sized clusters enriched in Zr. These local clusters do not show changes during the different thermal treatments, either for higher temperatures or longer times. No Zr phases are stabilised in the crystallised materials, suggesting that these clusters do not evolve above the critical nucleus size. All evidence points to a highly heterogeneous environment and the coexistence of three structural regions i) (sub)nano Zr-clusters, ii) P enriched μ-areas, iii) residual silicate glass. The evolution and spatial distribution of these units influence the final properties.},

abstract = {From initial calcium aluminosilicate glass, transparent glass-ceramics have been successfully synthesized under simultaneous high pressure and temperature (SHPT). Possible homogeneous volumetric crystallization of this glassy system, which was not achieved previously by means of conventional heat treatment, has been put in evidence with a SHPT procedure. Structural, mechanical, and optical properties of glass and glass-ceramic obtained were investigated. Raman spectroscopy and X-ray diffraction allowed to identify two main crystalline phases: merwinite [Ca3Mg(SiO4)(2)] and diopside [CaMgSi2O6]. A Raman scanning profile showed that the formation of merwinite is quite homogeneous over the bulk sample. However, the sample surface also contains significant diopside crystals. Instrumented Berkovich nanoindentation was applied to determine the effect of SHPT on hardness from glass to glass-ceramic. For Eu-doped samples, the broadband emission due to 4f(6)5d(1) -> 4f(7) transition of Eu2+ was studied in both host systems. Additionally, the D-5(0) -> F-7(J) transition of Eu3+ was used as an environment probe in the pristine glass and the glass-ceramic. Published by AIP Publishin},

abstract = {New glasses in the composition 60Sb2O3-(40-x) NaPO3-xWO3 (where x = 0 to 40 mol.%) were prepared using the melt quenching technique. Different physical properties were measured to explain the effect of replacing NaPO3 with WO3. Differential scanning calorimetry (DSC) measurements showed high thermal stability, with Tx-Tg ∼ 100–130 °C. Glass transition temperature, Tg increased with an increasing amount of tungsten oxide. Such increase is also observed for the measurement of density, micro hardness, and the elastic moduli (longitudinal modulus (L), shear modulus (G), bulk modulus (K), and Young's modulus (E)). However, Poissn's ratio remains practically invariant and close to 0.252 confirms the bi-dimensional structure. The insertion of WO3 reduces the optical band gap and increases the refractive index from 1.584 to 1.786 at 486.1 nm where x WO3 is from 0 to 25 (mol.%). Furthermore, the measured optical dispersion changes from low dispersion crown glass to more dispersive flint glass. Following these various results, the glasses studied prove to be potential candidates for optical devices.},

abstract = {Aligned biodegradable fibers incorporating bioactive glass particles are being highly investigated for tissue engineering applications. In this study, 5, 7 and 10 wt% melt-derived 1393B3 borate glass (BG) microparticles (average size: 3.15 µm) were incorporated in 83 wt% polycaprolactone (PCL) and 17 wt% gelatin (GEL) (83PCL/17GEL) solutions to produce aligned electrospun composite nanofiber mats. Addition of 5 wt% BG particles significantly increased the alignment of the nanofibers. However, further incorporation of BG particles led to reduced degree of alignment, likely due to an increase of viscosity. Mechanical tests indicated a tensile modulus and tensile strength of approximately 51 MPa and 3.4 MPa, respectively, for 5 wt% addition of 1393B3 BG microparticles, values considered suitable for soft tissue engineering applications. However, with the increasing amount of 1393B3 BG, the nanofiber mats became brittle. Contact angle was reduced after the addition of 5 wt% of 1393B3 BG particles from∼45° to∼39°. Cell culture studies with normal human dermal fibroblast (NHDF) cells indicated that 5 wt% 1393B3 BG incorporated nanofiber mats were cytocompatible whereas higher doping with 1393B3 BGs reduced biocompatibility. Overall, 5 wt% 1393B3 BG doped PCL/GEL nanofiber mats were aligned with high biocompatibility exhibiting desirable mechanical properties for soft tissue engineering, which indicates their potential for applications requiring aligned nanofibers, such as peripheral neural regeneration.},

abstract = {In this work, we study the relaxation behavior of a densified sodium aluminoborate glass by means of coupled Raman spectroscopy, Brillouin spectroscopy, and differential scanning calorimetry analyses. First, we show that the changes in elastic properties upon densification are largely associated with structural modifications in the glass network at shortand medium-range orders. Then, the evolution of the structural and elastic properties of the densified glass has been monitored in situ in the coupled DSC-Brillouin-Raman setup during isothermal annealing at different temperatures below the glass transition temperature. The stretched exponential function is found to well describe the observed relaxation kinetics, however, the stretching factor beta varies non-monotonically with temperature. In contrast, the Arrhenius behavior of the characteristic decay times is deduced by lifetime distribution analysis, revealing three different relaxation processes with typical activation energies of 170 +/- 25, 200 +/- 5, and 280 +/- 15 kJ/mol. The relative contributions of these processes to the overall relaxation kinetics are found to vary with the temperature as well as the type of parameter considered (structural, elastic, or thermal), and hence, the relaxation kinetics cannot be properly understood using the stretched exponent function. The possible origins of the different relaxation processes are discussed. (c) 2020 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.},

abstract = {Densified SiO2 glasses, obtained from different pressure and temperature routes, have been annealed over a wide range of temperatures far below the glass transition temperature (500 degrees C-900 degrees C). Hot and cold compressions were useful to separate the effects of pressure and the compression temperature. In situ micro-Raman spectroscopy was used to follow the structural evolution during the thermal relaxation. A similar glass structure between the non-densified silica and the recovered densified silica after the temperature annealing demonstrates a perfect recovery of the non-densified silica glass structure. While the density decreases monotonically, the structural relaxation takes place through a more complex mechanism, which shows that density is not a sufficient parameter to fully characterize the structure of densified silica glass. The relaxation takes place through a transitory state, consisting in an increase of the network inhomogeneity, shown by an increase in the intensity of the D2 band which is associated with 3 membered rings. The activation energy of these processes is 255 +/- 45 kJ/mol for the hot compressed samples. The kinetic is overall faster for the cold compressed samples. In that last case, the relaxation is partially activated by internal stresses release. Published by AIP Publishin},

abstract = {Layered multi-material ceramics are natural candidates for modern engineering applications due to their attractive mechanical properties. Residual stresses caused, for example, by a thermal mismatch during the processing of these materials can significantly affect their mechanical properties. In this work, Raman investigations were performed to estimate these residual stresses in layered reaction-bonded silicon carbide (RBSC) and reaction-bonded boron carbide (RBBC) composites fabricated by robocasting. The Raman measurements show that the residual stress in the silicon phase of RBSC and RBBC composites has a different sign, which can explain the crack formation that occurred after Si infiltration. To adjust the stresses and prevent this cracking, a new paste composition was investigated. SEM micrographs and Raman measurements showed that almost crack-free layered composites with similar stresses in the different layers could be realized. In addition, well-known analytical approaches were used to calculate these residual stresses.},

Despite this, a number of challenges remain, such as an enhanced electrical conductivity and internal residual stresses in as-deposited films. In this work, a novel technique that integrates a sacrificial water-soluble buffer layer was used to fabricate freestanding ceramic thick films, which allows for direct observation of the film without influence of the substrate or prior thermal treatment. Here, the temperature-dependent chemical and structural relaxation phenomena in freestanding BaTiO3 films were directly investigated by characterizing the thermal expansion properties and temperature-dependent crystal structure as a function of oxygen partial pressure, where a clear nonlinear, hysteretic contraction was observed during heating, which is understood to be influenced by lattice defects. As such, aliovalent doping and atmosphere-dependent annealing experiments were used to demonstrate the influence of local chemical redistribution and oxygen vacancies on the thermal expansion, leading to insight into the origin of the high room temperature conductivity of as-deposited films as well as greater insight into the influence of the induced chemical, structural, and microstructural changes in room temperature deposited functional ceramic thick films.},

well-controlled conditions yields flake-like particles with high aspect

Electrochemical characterization by cyclic voltammetry, electrochemical
impedance spectroscopy, galvanostatic charge/discharge cycles and rate
capability measurements indicates that the flakes show superior
electrochemical properties compared to the bulk glass counterparts with a
stable specific capacity of 620 mAh g−1 after 100 cycles. The majority of charge is stored by Li+
ion diffusion inside the material and impedance spectroscopy shows
enhanced lithium ion diffusion capabilities of the flakes. The proposed

abstract = {Small-molecular-weight (MW) additives can strongly impact amorphous calcium carbonate (ACC), playing an elusive role in biogenic, geologic, and industrial calcification. Here, we present molecular mechanisms by which these additives regulate stability and composition of both CaCO3 solutions and solid ACC. Potent antiscalants inhibit ACC precipitation by interacting with prenucleation clusters (PNCs); they specifically trigger and integrate into PNCs or feed PNC growth actively. Only PNC-interacting additives are traceable in ACC, considerably stabilizing it against crystallization. The selective incorporation of potent additives in PNCs is a reliable chemical label that provides conclusive chemical evidence that ACC is a molecular PNC-derived precipitate. Our results reveal additive-cluster interactions beyond established mechanistic conceptions. They reassess the role of small-MW molecules in crystallization and biomineralization while breaking grounds for new sustainable antiscalants.},

Thermal and optical properties, including the optical basicity, were correlated with structural variations. IR and Raman spectra showed the highest N4 fraction for the high basicity glasses, decreasing for higher field strength ions (Ba>Sr>Ca>Mg). As determined from far IR bands the mixing of dissimilar cations affects M-O interactions. The glass transition temperature Tg correlates well to the average bond strength of the compared alkaline earth ions. The redox ratio of Mn2+/Mn3+ or Cu2+/Cu+ shifted to lower valences in low basicity glasses. The optical basicity probe ion Mn2+ gives consistently higher values compared to the average optical basicity, suggesting that Mn2+ ions seek out high basicity ligands.},

abstract = {Light-induced halide segregation limits the bandgap tunability of mixed-halide perovskites for tandem photovoltaics. Here we report that light-induced halide segregation is strain-activated in MAPb(I1−xBrx)3 with Br concentration below approximately 50%, while it is intrinsic for Br concentration over approximately 50%. Free-standing single crystals of CH3NH3Pb(I0.65Br0.35)3 (35%Br) do not show halide segregation until uniaxial pressure is applied. Besides, 35%Br single crystals grown on lattice-mismatched substrates (e.g. single-crystal CaF2) show inhomogeneous segregation due to heterogenous strain distribution. Through scanning probe microscopy, the above findings are successfully translated to polycrystalline thin films. For 35%Br thin films, halide segregation selectively occurs at grain boundaries due to localized strain at the boundaries; yet for 65%Br films, halide segregation occurs in the whole layer. We close by demonstrating that only the strain-activated halide segregation (35%Br/45%Br thin films) could be suppressed if the strain is properly released via additives (e.g. KI) or ideal substrates (e.g. SiO2).
2Si2O8 (anorthite) glass in situ up to 20 GPa, based on Brillouin and Raman spectroscopy results. In situ high-pressure Brillouin spectra of CaAl2Si2O8 glass were taken during two compression-decompression cycles. The second compression-decompression cycle up to 12 GPa displayed a perfectly elastic behavior indicating that 8% faster sound velocity arose from permanent densification during the first cycle. The longitudinal sound velocity was calculated from previously reported refractive index data and displayed distinct changes in behavior at 2 and 5 GPa. Anorthite (CaAl2Si2O8) glass displays an anomalous decrease in the longitudinal sound velocity up to ∼2 GPa. Above this pressure its longitudinal sound velocity is insensitive to pressure until 5 GPa and thereafter it displays a positive pressure dependence. The longitudinal sound velocity of CaAl2Si2O8 glass is quite distinct from both polymerized (e.g. silica, albite) and depolymerized (e.g. diopside) silicate glasses. Raman spectroscopy reveals that below 2 GPa there is a rapid decrease in the inter-tetrahedral angle within the aluminosilicate network. In fact, the sigma parameter, indicative of the overall intertetrahedral angle, displays three distinct pressure regimes comparable to the longitudinal sound velocity. The lowest pressure regime, <2 GPa, involves a wrinkling of four-membered tetrahedral rings as well as the formation of fivefold coordinated aluminum. Between 2 and 5 GPa, the closure in the inter-tetrahedral angle becomes weak and the Raman bands associated with the three- and four-membered tetrahedral rings are lost. Above 5 GPa, new contributions to the spectra indicate the presence of either fivefold silicon or sixfold aluminum. Comparison with silica and sodium aluminosilicate glasses leads to the suggestion that the sharp changes at 5 GPa may be attributed to the formation of highly coordinated silicon because aluminum coordination changes are thought to be continuous. The loss of the tetrahedral rings and the formation of highly coordination tetrahedral cations, such as Si or Al, could be accomplished if the tetrahedral cations form edge-sharing geometries. In contrast to known polymerized (e.g. silica, albite) and depolymerized (e.g. diopside, enstatite) silicate glasses, CaAl2Si2O8 glass displays a weak negative pressure dependence, as found in polymerized compositions, but a high overall longitudinal sound velocity, as found in depolymerized systems. These structure-property relationships suggest that fragility is a better measure of the high-pressure behavior of silicate glasses.},

abstract = {The process of laser filament cutting produces a practical nongap cut which ensures high precision in lateral dimensions at the micrometer scale. Commercially available OptiWhite soda lime silicate glass is filamented using a 1064 nm picosecond pulsed Nd:YAG laser with varying burst energies and focus positions. The filaments are characterized perpendicular to the incident laser beam using scanning electron microscopy (SEM). Maximum roughness Rz evaluated with laser scanning microscopy is measured on the cut sides. The characteristic mechanical strength σ of glass cleavage is decreased by a factor of 6 with the presence of the filaments. This σ obtained in the four-point-bending setup decreases with the increase in energy deposited in the material by the laser. It is found that the cleaving cracks are guided by the filament only if the network of microcracks is sufficiently developed. A threshold of the cleaving guidance is linked to a critical surface modification width of 2.5 μm which corresponds to half the distance between filaments. The influences of the laser parameters, sample thickness, and sample position in respect of the focal plane on the cut quality are studied. Guidelines are given to define a suitable parameter set.},

The results showed that crystalline phases in glass-ceramic belong to the family of melilite Ca2Mg0.25Al1.5Si1.25O7 as the major phase and anorthite CaAl2Si2O8 as the minor phase. Luminescent properties were investigated by emission; lifetime and the color points were calculated. Emission spectra showed that Eu2+ entered into the crystalline phase in a two steps mechanism: first as Eu2+ which is then reduced to Eu2+. This incorporation in the crystal enhanced Eu2+ emission with increasing time of heat-treatment and therefore crystallization. (C) 2014 Elsevier B.V. All rights reserved.},

abstract = {The characterization of aluminosilicate glasses is highly relevant in geosciences and for engineering applications such as reinforcement fibers or touchscreen covers. The incorporation of phosphate as a third network-forming species into these glasses offers unique opportunities for fine-tuning glass properties via changes in glass structure and polymerization. In this work, we studied melt-quenched aluminosilicate glasses within the system SiO2-Al2O3-Na2O-P2O5 with 50-70 mol% SiO2 and up to 7.5 mol% P2O5. All glasses were metaluminous (Al:Na = 1) in order to maximize the degree of polymerization. Increasing the phosphate content at the expense of NaAlO2 led to reduced glass polymerization and density, resulting in a decrease in elastic moduli and hardness and an increase in strain-rate sensitivity. When increasing the silica content by substituting SiO4 for AlO4 tetrahedra, network polymerization remained mostly unchanged, as confirmed by nearly constant hardness. Densification upon indentation was analyzed by Raman spectroscopy and finite element analysis. We find that the elastic properties and hardness of metaluminous phospho-aluminosilicate glasses are governed by changes in density and network polymerization. Other mechanical properties underlie more complex changes in glass structure.},

abstract = {Rare Earth Elements-doped glasses have applications in many fields, and for example, Al and Ce codoping in silica optical fibers is usually done to attenuate the optical degradation (photodarkening) of, e.g. Yb and Tm doped silica optical fibers. To shed some light on the effect of codoping on the optical properties and the glass structure of SiO2 fibers, we investigated a SiO2 fiber preform having a gradual increase of the CeO2 + Al2O3 content from 1.5 to 6.3 mol% and a CeO2/Al2O3 molar ratio varying from 0.04 to 1.4. Raman and photoluminescence spectroscopies have been used to evaluate changes in the short- and medium-range order both in the cladding and in the core portions, and the evolution of the glass optical properties, respectively. The variations of the excitation and emission have been linked to modifications in the vibration bands of the Raman spectra, and in turn, the relationship between optical properties and glass connectivity has been carefully considered. Our results show that there is a strong positive linear relationship between the increase of the Raman bands in the high-frequency range and the red-shift of the excitation maxima. Therefore, the change of distances and bond covalency character influences, in the same way, both the photoluminescence behavior of the core and the connectivity of the amorphous network.},

The aim is to gain insight into the complex phase boundary region responsible for the excellent electromechanical properties. The results demonstrate the correlation between local site substitutions based on the stoichiometric variations to the microstructure and dielectric properties. The dielectric response has been correlated with the BCT/BZT content displaying a maximum depending on the phase content. Additionally, in situ temperature-dependent Raman, permittivity, and pair distribution function (PDF) studies were performed from −60 °C to 130 °C to highlight the structure and phase evolution. In particular, the in situ temperature-dependent Raman measurements reveal sudden discontinuities in the vibrational modes that correspond to the structural changes in the perovskite structure. Therefore, the results of the permittivity response, based on the average of a large volume, are consistent with the local structural changes obtained by other techniques. Indeed, correlations of Raman, X-ray diffraction, and PDFs obtained from synchrotron X-ray total scattering data, along with permittivity measurements allowed the identification of the discrete ferro- to paraelectric phase transitions and a more robust characterization. The rotation and distortion of the octahedral caused by oxygen displacement are driving forces behind symmetry changes and phase transitions, explaining the mechanism of polymorphic phase transition based on A- and B-site substitution. Therefore, this work provides a comprehensive understanding of temperature and composition-dependent phase transitions in BCZ},

abstract = {X-ray absorption near-edge structure (XANES) spectroscopy has been used to investigate the local structural environments around each of the elements within the haplobasaltic system. The XANES results reveal both, linear changes in Ca, O and Si whereas non-linear changes are also observed for Si as well as Al and Mg. Unexpectedly, both Si and Al spectra show complex edge structure that varies non-linearly across the join. The Si L-2,L-3-edge results suggest that the Si environment in An100 is very similar to that in crystalline anorthite whereas the Di100 and diopside spectra show large offsets. The L-3 and L-2 peaks display a linear behavior where as peak B of the Si L-2,L-3 spectra displays a non-linear behavior displaying a maximum position at the Di40 and Di100 compositions and decreasing in between. We estimate the Si-O bond length from shift in the peak B position which suggests a change in bond length between 1.58 and 1.66 angstrom across the join. The Al K-edge spectra suggests that there is a constant decrease in the inter-tetrahedral angle as Al is added. The local Mg environment displays non-linear changes in intensity and for compositions with An content greater than Di40 it appears that Mg-[4] plays an important role whereas Mg-[5] is dominant in diopside-rich melts, though octahedral coordinated Mg cannot be ruled out. The oxygen environment appears similar to crystalline anorthite in the haplobasaltic system. Calcium is present in highly distorted sites that are dominantly Ca-[7] in anorthite-rich glasses where as Ca-[8] is more important in diopside-rich glasses. These results provide additional independent constraints on the atomic structure of haplobasaltic silicate melts and highlight the need for further investigation into the relationships between network formers, modifiers and the oxygen to which they are bound.

The effects of different Sr/Ca ratios, types of monovalent metal ions (M+ = Na+, K+, and Li+), and doping concentrations were systematically investigated. The crystalline phase, photoluminescence (PL) properties, lattice site occupied by the Eu3+ ion, Eu3+ site distribution, and site-selective PL properties were evaluated by x-ray diffraction, PL/photoluminescence excitation (PLE) spectroscopy with a monochromatic light source, PL quantum efficiency (QE) measurements, and high-resolution PL/PLE spectroscopy with a wavelength-tunable laser. A dependence of the PL asymmetry ratio for the 5D0–7F1,2 transitions on the Sr/Ca ratio was identified and quantified for the first time. Based on the site-selective PL measurements, this behavior was ascribed to the enhancement of Eu3+ local distortion by Sr2+ substitution at the A site at lower Sr/Ca ratios (<2) and to the high symmetry of the ligand structure of EuO6 octahedra owing to Ca2+ substitution at the B site at higher Sr/Ca ratios (>2). The PLE results provided insight into the Eu3+ site distribution, which explained the orange-red PL and PL QEs of the synthesized phosphors.
