Organic ruthenium complexes and polymers with electrochromic activity in the near infrared region were prepared and their electrochemical and optical properties were investigated. The intrinsic attenuating property of these materials depends mainly on the concentration of the pair of ruthenium units in the complexes or polymers. One cured film had the attenuating power of 6.9 dB per micron thic...

Hemoglobin can exhibit not only a direct electron transfer reacting after being entrapped in a DNA membrane, but also a greatly enhanced peroxidase activity toward the reduction of hydrogen peroxide. Based on the direct electrochemical property and nice enzymatic activity of the protein in a DNA membrane, a reagentless hydrogen peroxide biosensor was prepared. The peak current related to hydrog...

Performance criteria namely Material Removal Rate (MRR), Surface Roughness (SR) and Radial Over Cut (ROC) in electrochemical machining process greatly affected by the machining parameters like electrical parameters, electrode parameters, electrolyte parameters and workpiece properties. In the present work applied voltage (electrical parameter), tool feed rate (electrode parameter), electrolyte ...

Large-scale vertically aligned ZnO nanowires with high crystal qualities were fabricated on thin graphene oxide films via a low temperature hydrothermal method. Room temperature photoluminescence results show that the ultraviolet emission of nanowires grown on graphene oxide films was greatly enhanced and the defect-related visible emission was suppressed, which can be attributed to the improve...

Four oxide clusterfullerenes Ho 2 O@C 90 (I–IV) were prepared by a modified arc discharge method and isolated multistage high performance liquid chromatography procedure. Based on their vis-NIR spectra, the carbon cage symmetries in (I, III, IV) are confirmed to be C (43)-C , (40)-C (41)-C respectively. Electrochemical studies display that first second reduction potentials of isomers close thos...
