Highly Hydrophilic TiO Nanoparticles as Stabilizers of Pickering Emulsions with Photosensitive Lipophilic Compounds: Synthesis and Application.

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.

Effect of -BN Support on Photoluminescence of ZnO Nanoparticles: Experimental and Theoretical Insight.

Herein we report a simple and easily scalable method for fabricating ZnO/-BN composites with tunable photoluminescence (PL) characteristics. 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.
