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: The effects of atmospheric-pressure air plasma treatment on the surface properties of common float soda-lime glass were studied using four different plasma sources. The purpose of the studied treatment was to remove contamination and activate the surface with hydrophilic functional groups, without affecting the surface morphology, by balancing the involved mechanisms. Comparing four plasma sources with different physical characteristics provided valuable information about their potential use for applications that involve adding materials to glass surfaces in the form of thin films, coatings, and layers.

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: 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: Architectural soda-lime silicate glass (SLS) is becoming more complex in shape, requiring detailed numerical analysis. However, accurate modeling of SLS glass requires precise material parameters that are sensitive to changes in glass composition. This study aims to update the information on key parameters for modeling using current SLS glass. Experimental investigations have been conducted on the coefficient of thermal expansion, glass transition temperature, and Young's modulus of SLS glass used in construction. The updated material parameters will enable more accurate modeling and faster production time for glass with complex geometries.

Summary: The corrosion behavior of soda-lime silicate float glass on fresh active surfaces is investigated. The initial stages of surface corrosion involve ion diffusion and ion exchange. A unique subsurface activity is reported in the glass, achieving equilibrium at approximately 10-30 nm depth, visibly manifested as a broad peak in the elemental depth profile. Prolonged corrosion and heating facilitate surface relaxation, leading to the formation of active nucleation sites for the corrosion process.

Summary: This study focused on the mechanical properties of soda-lime silicate glass under compression, tension, and flexure. Quasi-static and dynamic tests were performed, and the effects of loading rates, specimen sizes, stress waves, and loading modes on the mechanical behavior of the glass were investigated. The results showed that specimen size and strain rate significantly influenced the strengths, and the compressive strength was sensitive to the loading stress waves. The flexural strength was generally higher than the tensile strength, and they could be converted through the non-local failure theory.

Summary: We investigated transparent Ca-Al-Si-O-N glasses with various nitrogen contents. The physical properties and elastic moduli of the glasses showed a rough linear dependence on the nitrogen content. The improved glass-network cross-linking from N rather than the formation of higher-coordination AlO5 and AlO6 groups primarily contributed to these effects.

Summary: We investigate the properties and structure of cerium pyrophosphate glasses and partially substituted cerium silicophosphates. The majority of cerium in these glasses is in the Ce(III) state. A combination of dynamic nuclear magnetic resonance and electrical impedance spectroscopy is utilized to determine the cerium speciation. Optical spectroscopy is limited in quantifying the ratio of Ce(III)/Ce(IV), but the effects of silica-for-cerium substitution on optical extinction and the UV band gap provide supporting evidence from vibrational spectroscopy. The stabilization of Ce(IV) by silica bonding to phosphate units restricts polaron transport, resulting in higher polaron activation energy and lower electronic conductivity. Meanwhile, Ce(III) is stabilized by coordinating to P = O.

Summary: The fabrication of metal-organic framework (MOF) thin films is essential for integrating these materials into electronic and optical devices. However, the limited structural variety of MOF thin films prepared through layer-by-layer deposition has been a challenge. In this study, a fast method for the preparation of MIL SURMOF on Au-surfaces was developed, allowing for the deposition of adjustable thickness thin films within 60 minutes. The resulting MIL-68(In) thin films showed high optical quality and mechanical properties, making them suitable for use as optical read-out sensors.

Summary: Electrothermal poling effectively induces second-order nonlinear effects in heavy-metal oxide antimonite glasses. The study reveals that the poling-induced second-harmonic generation intensity is influenced by the alkali type. X-ray photoelectron spectroscopy and spectroscopy analysis confirm the presence of different molecular units in the glass network. Raman spectroscopy line scans track structural changes on the anode side of poled glasses and show an increase in partially polymerized tungstate units.

Summary: The impact of crystallinity on the structural, thermal, and in vitro dissolution properties of Na2O-CaO-Nb2O5/MgO-P2O5 glasses/glass-ceramics was investigated. Glass-ceramics were synthesized through spontaneous crystallization. The Nb content in the materials increased with melting temperature, and the crystallinity was directly proportional to the Nb content. FTIR analysis confirmed the presence of crystalline niobates and phosphates, which was consistent with XRD results. The phosphate network was found to consist of different proportions of Q2, Q1, and Q0 units, depending on the amount and type of crystalline phase. Most samples exhibited improved thermal stability. The in vitro dissolution test showed that the highest mass loss occurred within the first 6 days of immersion, with smaller phosphate crystals favoring the deposition of hydroxyapatite while larger niobate crystals dissolved more readily.

Summary: In this study, the concept of genes as fictive chemical entities with a characteristic stoichiometry is used to describe the relationships between structure and ionic conductivity in polyionic glasses. Strong linear component analysis (SLCA) is employed to optimize the selection of essential genes from all possible combinations of elements, and family trees and matrix rotation analysis are used for filtering. The structural interpretations are also compared with spectroscopic experiments for validation.

Summary: The controlled nanocrystallization of the sodium-calcium-borophosphate glass was studied to investigate its effect on in vitro dissolution. Different temperatures were selected, and the glass and glass-ceramics were analyzed for their morphology, structure, and dissolution properties. The results show the presence of calcium phosphates nanocrystallites in glass-ceramics, with their content increasing with higher crystallization temperatures. Controlled nanocrystallization slowed down the dissolution, but did not affect the deposition of hydroxyapatite. The presence of calcium phosphate nanocrystallites enhances B3+ release and has potential applications in controlling dissolution rate and enhancing hydroxyapatite deposition.

Summary: This paper presents a method for non-destructive testing of glass strength. Samples of annealed float glass were subjected to controlled Vickers microindentation-induced cracking and compared to un-indented samples. The non-destructive testing using nonlinear acoustic waves resulted in defect values, which were found to correlate linearly to the indentation force. Ring-on-ring testing yielded realistic strength values in the range of 45 to 110 MPa. The study shows that a non-destructive testing method for glass strength is feasible.

Summary: In this study, silicate glass containing crystals were prepared by melting a mixture of YbPO4 xenotime structured crystals and SiO2 nanoparticles. The mixture was used to prepare large volume core preforms for laser active optical fiber. The integrity of the crystals in the preform and fiber were assessed through temperature dependent sintering and fiber drawing experiments. The survival of YbPO4 crystalline particles in silica was investigated using various techniques, showing that the particles withstand the high-temperature steps during the fiber fabrication process. However, partial decomposition of the crystals was observed during the fiber fabrication.
