Tin oxide (SnO2) hollow spheres modified with titanium dioxide (TiO2) nanowires (NWs) synthesized by sequential hydrothermal reactions were investigated as photoanodes for dye-sensitized solar cells. Not only does the hydrothermal treatment form numerous short TiO2 NWs on the surface of SnO2 spheres, but also passivates the surface of SnO2. Consequently, the specific surface area of the photoan...

NiCu alloy nanowires arrays were embedded into the anodic aluminum oxide (AAO) template by ac-pulse electrodeposition. Different off-time were used in electrolyte with constant concentration of Ni and Cu and acidity of 3. The effect of deposition parameters on alloy contents was investigated by studying the microstructure and magnetic properties of as-deposited NiCu alloy nanowires. Atomic forc...

in this paper, a numerical solution procedure is presented for the forced vibration of a piezoelectric nanowire under thermo-electro-mechanical loads based on the nonlocal elasticity theory within the framework of timoshenko beam theory. using hamilton’s principle, the nonlocal governing differential equations are derived. the governing equations and the related boundary conditions are discreti...

Cu2O is a narrow band gap material serving as an important candidate for photoelectrochemical hydrogen evolution reaction. However, the main challenge that hinders its practical exploitation poor photostability, due to oxidation into CuO by photoexcited holes. Here, we thoroughly minimize photo-oxidation of nanowires growing thin layer TiO2 protective and amorphous VOx cocatalyst using magnetro...

the aim of this research is preparation of sno2 nanowires by means of thermal chemical reaction vapor transport deposition (tcrvtd) method from sno powders. the morphology, chemical composition and microstructure properties of the nanowires are characterized using field emission scanning electron microscope (fe-sem), eds, and xrd. the xrd diffraction patterns reveal that the sno2 nanowires have...
