Summary: Soda lime silicate glasses doped with metal oxides were synthesized and their optical and physical properties as well as the effect of gamma irradiation were investigated. The FTIR analysis showed characteristic bands for silicate units, while UV-Vis spectra revealed absorption bands of different metal oxides. After gamma irradiation, changes in the glass network stability and the appearance of new defects were observed. ESR spectroscopy elucidated the defect centers induced by ionizing gamma irradiation.

Summary: In this study, the in situ dynamic crystallization properties of industrial soda-lime-silica glasses at realistic processing temperatures were investigated. Unique crystalline phases were observed at lower temperatures, and high-temperature stable SiO2 polymorphs were also observed. The main predictor variables in the previously developed liquidus temperature models were found to be questionable, and a large difference between glass processing and liquidus temperatures was identified.

Summary: The glass formation region has been determined for the soda lime germanate system, which includes both homogeneous and phase separated glasses. The homogeneous glasses exhibit behavior typical of the germanate anomaly, while the phase separated glasses' properties can be explained by considering the effect of morphology.

Summary: The addition of alumina to conventional soda lime silicate glass composition improves properties but also increases melting temperature. An anomaly in linearly increasing viscosity was found when the CaO/Al2O3 ratio is <1, explained by Ca2+ acting as an inhibitor for viscous flow. Thermodynamic data generally increases linearly with Al2O3 content, but there is a deviation in linearity for the Doremus fragility index.

Summary: Elastic moduli of SiO2-Na2O-CaO glasses doped with Sb2O3 were theoretically calculated, showing an increase with higher Sb2O3 contents. The addition of Sb2O3 was found to enhance the glasses' shielding parameters, with the highest linear attenuation coefficient achieved for SCNSb10 glass. The study also computed the fast neutron effective removal cross-section, revealing differences between samples with varying Sb2O3 contents.

Summary: The study revealed that the ZrO2 doping content has a significant influence on the electrical and dielectric properties of soda lime silicate glass, leading to a decrease in electrical parameters and an increase in resistivity. The addition of ZrO2 makes the internal structure of the glass more polymerized, electrically rigid, and resistant to the flow of free charge carriers.

Summary: Vickers indentation methods are popular for determining hardness, fracture toughness, and crack initiation resistance in silicate glasses due to their simplicity and efficiency. However, obtaining consistent and repeatable results from these measurements is challenging. In this study, we investigated the effects of applied load, dwell time, and post-indentation observation time on the precision of hardness and fracture toughness values for soda-lime silicate glass measured via Vickers microindentation. The results show that low applied loads and short dwell times result in low precision, while longer dwell times lead to higher precision and load-independent fracture toughness. These findings suggest that Vickers microindentation could be a reliable technique for measuring mechanical properties of silicate glass.

Summary: Shock experiments provide important insights into the behavior of matter under extreme conditions. In this study, laser-driven dynamic compression experiments were performed on soda-lime glass to understand the role of composition in the shock compression behavior of silicate glasses. It was found that the glass composition strongly influences the shock compression behavior and no transformation to the crystalline phase was observed up to 70 GPa.

Summary: The atomic structure of a soda-lime-aluminosilicate network glass that underwent two different thermal treatments has been investigated using in-situ Synchrotron Powder Diffraction experiments. The study revealed the volume variations, relaxation level, short range order characteristics, and structural features of the samples under different thermal treatments. The results describe the multiple over temperature phenomenology of the composition and show how the local range behaves independently from the sample's thermal history.

Summary: This study proposes two distinct approaches to predict the formation of the mirror-mist boundary in soda-lime glass. The crack-front's speed reaching a critical threshold is found to be the key factor in the formation of the "mist". Additionally, the thickness of the damaged zone predicted by phase-field can also be correlated to the formation of the fractographic features. The results obtained from these two methods are in good agreement with experimental observations.

Summary: This study investigates the phase stability, elastic modulus, and hardness of ternary nitride Ti1-xAlxN. It is found that the hardness increases with the Al content x. The cubic B1 structure is more stable for x < about 0.75, while the hexagonal structure (B4) is more stable for x > about 0.75. The composition dependent hardness and phase decomposition contribute to the convex shaped hardness curve of Ti1-xAlxN.

Summary: This report uses rigorous calculations based on density functional theory to study the piezoelectric and elastic properties of wurtzite aluminum nitride (w-AlN) with single- and co-alloying by Hf (or Zr) and Sc. The research finds that the (HfSc)0.375Al0.625N and (ZrSc)0.375Al0.625N with stable wurtzite phase have a large piezoelectric coefficient d33 of 49.18 pC/N and 47.00 pC/N, respectively. However, the piezoelectric voltage constant g33 and electromechanical coupling constant k233 of HfAlN, ZrAlN, HfScAlN, and ZrScAlN are smaller than that of ScAlN, which is attributed to the large dielectric constant epsilon 33 of Hf (or Zr) alloying samples. Furthermore, the calculations of internal parameter u and bond angle alpha elucidate the brittle-to-ductile transformation in alloying w-AlN crystal structure. Electronic structure calculations show that the bandgap decreases almost linearly with the increase of alloying concentration, and the Hf (or Zr) alloying compounds become n-type semiconductors due to the existing high-charge states.

Summary: This work presents a multilayer film structure that uses optical resonance to prepare highly efficient and saturated red, green, and blue transmittance colors. Numerical simulations and analysis show that the structure can produce R, G, and B colors with a purity comparable to standard RGB colors, while maintaining efficient transmission efficiency and obtaining a rich variety of structural colors. Additionally, a metallic interlayer is introduced to selectively suppress resonances in the short-wavelength region, improving the purity of the red color. The study also investigates the effect of the incidence angle on color purity and transmission efficiency.

Summary: Solubility property is of great interest in chemical, physical, pharmaceutical, material, and environmental sciences. Understanding the intrinsic reason behind solubility behavior is a fascinating task. The theoretical relation between binary mutual solubility and liquid-liquid interfacial tension has been derived, where the partitioning of solute molecules between two coexisting liquid phases is determined by the transfer free energy per unit segment for a chain-like solute molecule expressed in terms of solute-solvent interfacial tension. This general theory of solubility is in good agreement with experimental results for binary mutual solubility and molar transfer free energy of solute molecules.

Summary: The influence of ZrOn matrix stoichiometry on the electrical and magnetoresistive properties of Fe-Zr-O nanocomposites has been studied. It was found that the magnetoresistive effect is not observed in composites with oxygen lack, while composites with oxygen excess show magnetoresistive effect and increased resistivity. Magnetoresistivity in composites with oxygen lack only appears after heat treatment. These results can be explained by the difference in the density of localized states in the oxide matrix of the composites and the ratio between two types of conductivity.
