Summary: The 58S Na2O-CaO-SiO2-P2O5 bioactive glass was successfully prepared through a high-temperature melting process, and its nucleation, crystallization behavior, and hydroxyapatite precipitation were investigated. Optimal nucleation and crystallization conditions can produce 58S bioactive glass-ceramics with spherical nano-scale hydroxyapatite crystals. Compared to 45S bioactive glass, the resulting 58S bioactive glass exhibits higher HA precipitation ability after treatment with artificial saliva, with brushite and HA phases precipitating simultaneously, showing higher bioactivity. The prepared 58S bioactive glass and glass-ceramic hold promise for use as bioactive materials in biomedicine and biotechnology.

Summary: This study investigates the properties of bioactive glass-ceramics obtained through controlled crystallization with different heat treatment times. The results show that the crystallinity and crystallite size increase with longer heat treatment, leading to enhanced bioactivity and higher ion exchange rate. The glass-ceramics also exhibit antibacterial activity against E. coli. These findings suggest that bioactive glass-ceramics have potential applications as biomaterials for treating bone fractures.

Summary: Glass has excellent friction, lubricating properties, and thermal stability, making it widely used in mechanical processing and other applications. This study analyzed the nucleation and crystal growth kinetics of SBBC system glasses and determined their crystallization kinetic parameters. The effects of time, temperature, and crystal phase on the crystallization rate curves were established. The crystal precipitation process of SBBC system glasses was verified through SEM images, and the negative effect of early crystallization on lubricating properties was observed.

Summary: Bioactive glasses (BGs) and glass-ceramics (BGCs) are versatile biomaterials used for various medical applications including bone bonding, soft tissue repair, and drug delivery. This study aims to redefine BGs and BGCs by comparing their structure, processing, and properties with other biomaterials, enabling consideration of all current and future applications. The proposed definitions emphasize the non-equilibrium, non-crystalline nature of bioactive glasses and the presence of at least one crystalline phase in glass-ceramics, both designed to induce specific biological activity. These materials have the potential to bond with bone and soft tissues, promote regeneration, and deliver therapeutic ions or other treatments for orthopedic, dental, and wound healing purposes.

Summary: The specific features of crystal nucleation have a significant impact on the morphology of the crystalline material. Due to their small size and stochastic nature, it is usually difficult to observe the development of nuclei directly. However, an experimental approach using fast scanning calorimetry has been developed to determine the specific features of the cluster size distribution. This approach allows for estimating the time evolution of the largest detectable clusters in the distribution and determining their radial growth rate.

Summary: The introduction of nanotechnology is promising for the fabrication of photoelectrodes, especially those based on two-dimensional materials. In this study, vertically aligned Bi2O3 nanosheet arrays were prepared using the Chemical Bath Deposition method. The physical and photoelectrochemical properties of the Bi2O3 nanosheet coatings were studied by varying the bath temperature and complexing agent concentration. The results showed that the bath temperature had a significant impact on the physical properties of the coatings, and the photoelectrode prepared at 60 degrees C exhibited the highest photocurrent density due to its lowest charge transfer resistance and narrowest bandgap.

Summary: This paper evaluated the microstructural features, physical properties, drug entrapment efficiency, and curcumin release kinetics of chemically-crosslinked gelatin/chitosan hydrogels loaded with zinc oxide nanoparticles and curcumin. The results showed that the addition of ZNPs and CUR led to a reduction in the average pore size of the hydrogels and an improvement in drug loading efficiency. The drug release kinetics were best described by the Hixon-Crowell, Higuchi, and Korsmeyer-Peppas models, indicating that curcumin release was controlled by diffusion and the degradation and swelling of the drug carrier.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
