We investigated the genotoxic responses to two types of TiO2 nanoparticles (<25 nm anatase: TiO(2)-An, and <100 nm rutile: TiO2-Ru) in human hepatoma HepG2 cells. Under the applied exposure conditions the particles were agglomerated or aggregated with the size of agglomerates and aggregates in the micrometer range, and were not cytotoxic. TiO2-An, but not TiO2-Ru, caused a persistent increase i...

Hetero-element doping (e.g., N, F, C) of TiO2 is inevitably accompanied by significantly increased structural defects due to the dopants' nature being foreign impurities. Very recently, in situ self-doping with homo-species (e.g., Ti(3+)) has been emerging as a rational solution to enhance TiO2 photoactivity within both UV and visible light regions. Herein we demonstrate that conventional elect...

Here, we report that the postsynthesis nitridation of tungsten oxide nanowires can result in single crystal nitride nanowires when the initial diameters of the nanowires are less than 10 nm. For nanowires with diameters greater than 10 nm, the nitridation of nanowires resulted in polycrystalline but highly oriented tungsten nitride domains in nanowires. Partially nitrided nanowires show an epit...

The perpendicular orientation of nanowires to electric fields would greatly improve the breakdown strengths (Eb) polymer-based nanocomposites; however, relatively small polarization at filler fraction, and thus unsatisfactory discharged energy density (Ud), restrict their further application. In this study, x vol.% TO@TO/PVDF nanocomposites with superior storage performances have been fabricate...

Iridium Oxide (IrO2) is a metal oxide with rutile crystalline structure, analogous to the TiO2 polymorph. Unlike other oxides of transition metals, IrO2 shows metallic type conductivity and displays low surface work function. also characterized by high chemical stability. These highly desirable properties make rightful candidate for specific applications. Furthermore, can be synthesized in form...
