Summary: The dielectric, physical, and optical properties of 5GeO2-30Li2O-55P2O5-(10-x)MgO-xCr2O3 (x varies from 0 to 0.9 mol%) glasses were investigated. The non-crystalline behavior of these glasses was analyzed using X-ray diffraction. The compact nature of the glasses was indicated by their physical parameters. The optical absorption spectra showed the presence of Cr3+ ions and the optical band gap and Urbach energy of the glasses were evaluated. Fourier-transform infrared and Raman spectra supported the structural changes in the glasses, while the emission and ESR spectra confirmed the presence of chromium ions.

Summary: Li2O-MgO-TiO2 ceramics with different magnesium contents were prepared, and the phase evolution, crystal structure, and microwave dielectric characteristics were investigated. It was found that Li2MgTi3O8, Li2Mg3TiO6, and (Li2TiO3)(10.667) coexisted at x = 1 and 2, while the pure Li2Mg3TiO6-like phase was obtained when x was increased to 3. The ceramics displayed porous structure and clear grain boundaries. The microwave dielectric characteristics were highly dependent on the chemical composition and densification. The Li2O-4MgO-TiO2 ceramics sintered at 1350 degrees C exhibited excellent comprehensive performance with ε(r) = 13.95, Q x f = 119,072 GHz, and τ(f) = - 40.9 ppm/°C.

Summary: The improvement of mechanical performance in glass and glass ceramics is crucial for various applications. In this study, alkaline earth oxides (MgO and CaO) were added to Li2O-Al2O3-SiO2 glass to enhance its mechanical properties. The ratio of CaO/MgO was found to affect the glass structures, with higher ratios leading to decreased bridging oxygen and connectivity. The density and molar volume of the glass increased linearly with the addition of CaO. Heat treatment resulted in the precipitation of different crystal phases, leading to changes in the mechanical properties of the glass ceramics.

Summary: The influence of adding [SiO2]/([P2O5] + [Al2O3]) on the radiation and elastic-mechanic characteristics of LMAS (Li2O-MgO-Al2O3-SiO2) glass systems was investigated. The density and LAC of the glass increased when P2O5 was substituted with Al2O3 at the expense of SiO2. The MAC values were found to be dependent on energy. The radiation shielding properties of the LMAS glass blocks were improved with the increase of [SiO2]/([P2O5] + [Al2O3]).

Summary: This study investigates the structure, microstructure, thermal and mechanical properties of glasses and glass ceramics in the LMAS system, as well as the effect of P2O5 and Al2O3 additives. The results show that the addition of P2O5 and Al2O3 increases the transition temperatures of glasses and glass ceramics, but decreases the melt viscosity at high temperatures. The main crystalline phases formed are lithium aluminium silicate, enstatite and 13-spodumene, and the shape and aspect ratio of crystallites depend on the concentration of Al2O3.

Summary: This study investigates the evaporation of fluoride from CaF2-CaO-Al2O3-MgO-Li2O-(TiO2) slag with different TiO2 contents. The evaporation ratio is promoted by increasing temperature and adding TiO2 content, but has a slight effect when TiO2 content exceeds a certain level. Major constituents of the evaporation substances are CaF2 and AlF3, with evaporation affected by the vapour pressure of AlF3 and the viscosity of the slag.

Summary: In this study, bioactive glass-ceramic (BGC) particles were synthesized using an acid catalyzed sol-gel derived route (Acid-BGC) and a modified Stober process under basic conditions (Basic-BGC). Acid-BGC showed complete conversion to a glass-ceramic form, while Basic-BGC exhibited reduced crystalline conversion. CTAB concentration was found to affect particle size and mesoporous structure of Basic-BGC, with 6 mM CTAB being the optimal concentration. Functionalization of Basic-BGC with glutamic acid enhanced its antibacterial, antioxidant, and bioactive properties without compromising dispersion stability. These findings suggest potential applications of functionalized Basic-BGC in bioprinting and electrospinning.

Summary: The effect of replacing P2O5 with different amounts of TiO2 on the crystallization, structure, and mechanical properties of an MgO-Al2O3-SiO2 system was investigated. The results showed that adding TiO2 favored the precipitation of fine grains and significantly increased the Vickers hardness, Young's modulus, and fracture toughness of the glasses. Introducing an appropriate amount of TiO2 can make a glass structure more compact, promote crystallization, and improve the mechanical properties of MgO-Al2O3-SiO2 glass-ceramics.

Summary: Through molecular dynamic simulations, the pressure-induced structural changes of ZIF-8 and SOD were studied. It was found that both materials undergo two transformations: amorphization process characterized by breakdown of mid-range structure without significant change in elastic modulus, and densification process involving changes in short-range structure and improvement in mechanical properties with increased short-range disorder.

Summary: Mineral wool, particularly stone wool, is an essential thermal insulation material for saving energy and preventing fire spread in buildings. This study developed a universal method to accurately quantify its high-temperature stability on a small scale, by measuring the silhouette area variation of a cylindrical wool fiber pellet during heating. Two main stages of shrinking were detected, and the key to ensuring the fire barrier role of stone wool lies in minimizing the first stage shrinking.

Summary: In this study, two series of bimetallic ZIF-62 were synthesized under different solvothermal conditions. The structure of the derived ZIF crystals was found to be highly sensitive to synthesis conditions. The substitution of Co for Zn led to a negative deviation from linearity in terms of melting temperature (T-m) and glass transition temperature (T-g). The new series showed a stronger negative deviation due to the mixed metal node effect. Both series exhibited different phases, with the new series having cobalt-rich and zinc-rich phases while the standard one only had a homogeneous phase. The study also demonstrated that the structure, melting behavior, and mechanical properties of ZIFs can be tuned by metal node substitution and synthetic conditions.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
