TiO2/ZnS/CdS Nanocomposite for Hydrogen Evolution and Orange II Dye Degradation by Václav Štengl, Daniela Králová

“…The method of UV-VIS diffuse reflectance spectroscopy was employed to estimate band-gap energies of prepared TiO2/ZnS/CdS nano-composites. The photocatalytic activity of the prepared samples were assessed by photocatalytic decomposition of Orange II dye in an aqueous slurry under UV irradiation at 365 nm wavelength and visible light up to 400 nm wavelength. …”

Research of Kinematic Parameter Calibration Method of 3-R2U2S Parallel Robot by Yuandong Wang, Jie Gao

“…Abstract The general methods of parameter calibration of parallel robot mechanism are analyzed， and a new parameter calibration method based on automatic cooperation principle for 3-R2U2S parallel robot is proposed. The principle is that all the influencing factors of positioning error are attributed to the change of robot mechanism parameters， and the comprehensive correction rod length influence factor including various error sources is obtained， then the more accurate kinematics inverse equation is finally obtained. …”
