Pickering emulsions are a very promising system for encapsulating and photoprotecting active ingredients. The highest photoprotection efficiency can be achieved when bare TiO nanoparticles are used as stabilizers. However, the main problem when using highly hydrophilic TiO nanoparticles is their inability to adsorb at the oil-water interface.

This study explores the influence of ZrN reinforcement on the microstructure and mechanical properties of AlSi10Mg metal-matrix composites. Utilizing high-energy ball milling (HEBM) and spark-plasma sintering (SPS), ZrN/AlSi10Mg composites were synthesized, achieving nearly full density with uniform ZrN distribution, while phase and chemical transformations were not observed in the bulk composites.

A promising drug delivery scaffold material for bone treatment applications is diopside (CaMgSiO) which is bioactive, degradable, and possesses drug-release ability. Currently, in vitro assessment of drug release from biomaterials is performed mostly on a 2D cell monolayer.

The -BN support significantly enhances the ultraviolet (UV) emission of ZnO nanoparticles (NPs), which is explained by the ZnO/-BN interaction and the change in the electronic structure of the ZnO surface. When -BN NPs are replaced with -BN microparticles, the PL in the UV region increases, which is accompanied by a decrease in visible light emission.
