Summary: The addition of SiO2 in the TiO2/SiO2 nanocomposite significantly enhances the photocatalytic and antibacterial abilities of the silicate coating, with the best performance observed at a SiO2 content of 15%. This is attributed to the larger surface area provided by TiO2/SiO2 Nc (15%) in the W silicate coating, which increases centers for absorption, photocatalytic reactions, and contact between the sample and bacteria.

Summary: NiTi shape memory alloy has broad applications in orthopedics and dentistry due to its superelasticity, shape memory effect, high corrosion performance, and biocompatibility. New horizons for biomedical applications of NiTi can be opened by improving its corrosion resistance and surface characteristics through appropriate pre-treatments. The type of pre-treatment influences the final properties of coated NiTi, with different treatments showing different advantages such as superior corrosion behavior, in-vitro bioactivity, or hydrophilicity. The deposition of a highly crystalline nano-HAp coating enhances the final characteristics of pre-treated NiTi, leading to superior corrosion resistance compared to mechanically polished NiTi.

Summary: Recently, there is increasing interest in superhydrophobic magnesium-based implants due to their superior corrosion resistance and specific anti-bacterial adhesion properties. However, the superhydrophobic surface hinders cell adhesion and proliferation, limiting the application of these implants. In this study, a superhydrophobic composite coating composed of hydroxyapatite, bismuth sulfide, and lauric acid was prepared on AZ31B Mg alloys. The composite coating exhibited a water contact angle of 156 degrees, providing excellent corrosion resistance and antibacterial properties. Additionally, the surface of the coating could be transformed from superhydrophobic to hydrophilic upon near-infrared light irradiation, offering effective protection for the Mg alloy substrate. The coated Mg alloy demonstrated high antibacterial efficiency against Staphylococcus aureus and Escherichia coli, and good biocompatibility with favorable cell viability and early cell growth and adhesion.

Summary: Low-temperature binder jetting is a promising method for printing hydroxyapatite composites. Optimal mechanical properties can be achieved by optimizing design parameters such as binder and powder properties. A water-based solvent and water-soluble polymeric adhesives were used for binder jetting of 3D printable hydroxyapatite powder. By blending different combinations and routes of hydroxyapatite, carboxymethyl chitosan, polyvinylpyrrolidone, and dextrin, a 3D printable powder with optimized flowability and packing density was prepared. Post-treatment in chitosan solution increased the compressive strength and Young's modulus.

Summary: Despite the hydrophobic surface of PDMS-based substrates limiting cell attachment and growth, this study found that a PDMS substrate coated with a combination of PDA and LME8 fragments can support the attachment and growth of hiPSCs, as well as their differentiation into iCMs. Compared to previous studies, the density of hiPSCs and their adhesion time on the PDMS surface were increased during iCM production. Additionally, this coated substrate required less manipulation and could be used under animal-free conditions. The results suggest that the PDA + LME8-coated PDMS substrate is a promising tool for cardiomyocyte production, tissue engineering, microfluidics, and organ-on-chip platforms.

Summary: Titanium silicon carbide (Ti3SiC2) MAX phase powder was synthesized using the molten salt synthesis (MSS) method. The purity and synthesis pathway of Ti3SiC2 were investigated, and Ti3SiC2 was successfully synthesized in high purity (93%) using graphite as the carbon source. The presence of Ti5Si3 silicide phase and the application of pressure and a different eutectic mixture also promoted the formation of Ti3SiC2 MAX phase. The formation mechanism involved reactions among Ti5Si3, TiC, and residual carbon.

Summary: The thermal stability and surface area of γ-alumina can be improved by incorporating various transition and rare earth metals. In this study, Zr and Zr-La doped alumina granules were synthesized, and the results showed enhanced thermal stability and surface area. The co-doping process with Zr and La dopants occupied vacancies in the alumina structure, preserving the mesoporous structure and suppressing α-alumina formation up to 1200 °C. These Zr-Al co-doped alumina granules can be suitable for industrial catalyst supports.
