Research on hydroxyapatite (HAP) coatings for bone tissue applications has been investigated for decades due to their significant osteoconductive and bioactivity properties. HAP closely resembles the mineral component of human bone, making it ideal for biomedical applications such as implants. This study investigates the synthesis of hydroxyapatite nanoparticles (HAP-NPs) via the microemulsion method, which is essential for creating HAP coatings on the Ti-6Al-4V substrate.

The rational design of multicomponent heterostructure is an effective strategy to enhance the catalytic activity of electrocatalysts for water and seawater electrolysis in alkaline conditions. Herein, MOF-derived nitrogen-doped carbon/nickel-cobalt sulfides coupled vertically aligned Rhenium disulfide (ReS) on carbon cloth (NC-CoNiS@ReS/CC) are constructed via hydrothermal and activation approaches. Experimental and theoretical analysis demonstrates that the strong interactions between multiple interfaces promote electron redistribution and facilitate water dissociation, thereby optimizing *H adsorption energy for the hydrogen evolution reaction (HER).

Magnesium (Mg)-based alloys have been recognized as desirable biodegradable materials for orthopedic implants. However, their clinical application has been limited by rapid degradation rates, insufficient antibacterial and osteogenic-promotion properties. Herein, a MgF priming layer was first constructed on AZ31 surface.

Magnetic liquid metal droplets, featured by unique fluidity, metallic conductivity, and magnetic reactivity, are of growing significance for next-generation flexible electronics. Conventional fabrication routes, which typically incorporate magnetic nanoparticles into liquid metals, otherwise encounter the pitfall pertaining to surface adhesivity and corrosivity over device modules. Here, an innovative approach of synergizing liquid metals with 2D magnetic materials is presented, accordingly creating chromium(III)-telluride-coated liquid metal (CT-LM) droplets via a simple self-assembly process.
