Summary: Silicate bioglass is essential in bone engineering for its bioactivity and osteogenic effects. The study synthesized hydroxyapatite-like bioactive glass based on the xSiO2-CaO-P2O5 system and investigated its structural evolution, apatite-forming ability, and cytotoxicity. Higher heat treatment temperature and lower SiO2 content increase crystallinity tendency and sample compactness, with 30Si sample showing remarkable mesoporous structures and high specific surface area, demonstrating excellent hydroxyapatite formation and no inhibitory effect on hPDLCs.

Summary: Silica hollow microspheres were prepared as biocompatible cell carriers using emulsified gelatin microspheres as sacrificial templates. SEM observations showed their spherical morphology with a hollow structure and a diameter of 50-200 μm. FT-IR spectrum revealed the presence of Si-O-Si bonds. Gelatin microspheres served as supporting matrix and sacrificial templates for the formation of hollow structure. The silica hollow microspheres were found to be biocompatible and supported cell attachment and proliferation when seeded with osteoblast MC3T3-E1 cells, indicating their potential as biocompatible cell carriers.

Summary: This paper analyzed the effects of polyacrylic acid (PAA) content on SiO2 films prepared by the sol-gel method using TEM, DLS, XRD, IR, SEM, and the transmission spectrum. The sol containing hollow spherical micelles can be prepared from tetraethyl orthosilicate (TEOS) and PAA as water-soluble polymer by improved Stober and template method. With the increase of PAA content, the particle size of hollow spherical silica colloidal particles increases and the quantity decreases. The transmittance of the glass increases with the increase of withdrawal speed, and the sample's transmittance decreases first and then increases with the increase of PAA content from 0.1g to 0.6g.

Summary: Researchers have prepared amine in-situ hybrid SiO2 aerogels with hierarchically porous structure, which overcome the limitations of high cost and low CO2 adsorption capacity in silica aerogels. The micropores constructed by the steric hindrance effect of long organic chain from bis[3-(triethoxysilyl)propyl]amine facilitate faster and more uptake of CO2. The obtained aerogels have high amine content, high specific surface area (up to 579.63 m2/g), and high pore volume, resulting in a fascinating CO2 capture ability of 6.57 mmol/g at 273 K, significantly higher than other silica-based aerogels.

Summary: The laser cladding coatings prepared on a titanium alloy substrate with a new precursor material system exhibit excellent wear resistance due to the presence of micron-size spherical graphitic phases and other reinforcement phases of high hardness. The formation mechanism of the graphitic phases involves in situ superassembly of uncombined C atoms and is closely related to the laser processing parameters and precursor compositions. These heterogeneous phases enable the obtained coatings to have high wear resistance and low friction coefficient, with a remarkable enhancement in wear resistance compared to the titanium alloy.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
