[ 1 ] - Dependence of Photocatalytic Activity of TiO2-SiO2 Nanopowders

Structural properties and chemical composition change the photocatalytic activity in TiO2-SiO2 nanopowder composite. The SiO2-TiO2 nanostructure is synthesized based on sol–gel method. The nanoparticles are characterized by x-ray fluorescents (XRF), x- ray diffraction (XRD), tunneling electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), UV-vis. Spectrophotometer and ...

[ 2 ] - Fabrication, and Effect of Reflux time on Structural Properties of Pure and Al-Doped TiO2 Nano-rod

TiO2 nanorods can be used as dye-sensitized solar cells and as various sensors and photocatalysts. These nanorods are synthesized by a using thermal corrosion process in a NaOH solution at 200 oC with TiO2 powder as a source material. In the present work, the synthesis of TiO2 nanorods in anatase, rutile and Ti8O15 phases and the...

[ 9 ] - Scale-Dependent Dynamic Behavior of Nanowire-Based Sensor in Accelerating Field

The accelerating fields (e. g. centrifugal acceleration and constant acceleration) can change the physical performance of nano-sensors significantly. Herein, a new size-dependent model is developed to investigate the scale-dependent dynamic behavior of nanowire-fabricated sensor operated in an accelerating field. The scale-dependent equation of motion is developed by employing a consolidation o...
