Comparison of Electrocatalytic Activity of poly(p-aminophenol) Film Supported Au-M (M= Pt, Cu and Ag) Bimetallic Nanoparticles for Oxidation of Sodium Borohydride

, , ,
In this study, a poly (p-aminophenol) film (PPAP) and bimetallic nanoparticles modified polymer film electrodes (GCE), Au-Pt/PPAP/GCE, Au-Ag/PPAP/GCE, Au-Cu/PPAP/GCE were prepared by electrochemical techniques. The modified electrode surfaces were characterized using atomic force spectroscopy, scanning [...]

Femtosecond transient absorption of plasmonic gold nanoparticles embedded in mesoporous TiO2 matrix: electron injection study

, , , , ,
Gold nanoparticles (AuNP) embedded in mesoporous films of wide band gap semiconductors such as TiO2 are used for promising applications in solar cells, visible light-sensitive photocatalysts, and biosensors developed on the basis of the surface [...]

Optimization of the electrical parameters of nematic and discotic liquid crystalline materials due to the dispersion of nano particles, nano tubes and quantum dots for display and photo-voltaic applications

, , , ,
Electrical parameters of the nano particle and carbon nano tube dispersed room temperature liquid crystalline materials 5CB and 6CHBT have been determined. Due to the dispersion, nematic to isotropic transition temperatures are highly affected. Threshold [...]
