In this article, nanocomposites based on Chitosan (CS)/ poly vinyl alcohol (PVA) and graphene oxide (GO) nanoparticles were prepared by casting the stable aqueous mixture of the components in a mold. The prepared nanocomposites were characterized using Fourier-transform infrared spectroscopy...

YBa2Cu3O7-d/graphene oxide (YBCO/GO) composite materials were fabricated by using powder metallurgy process combined with cold isostatic pressing (CIP) technique. The coefficient of friction (COF) of YBCO matrix composites with addition of 0, 0.5, 1.0 and 2.0 wt% GO were reported for the first...

Effects of the reduction temperature and the pH value of Pt precursor solutions of the polyol reduction process on the resulted Pt electrocatalysts supported on the reduced graphene oxide (Pt/r-GO) nanosheets for the ORR (oxygen reduction reaction) are investigated. The Pt/r-GO catalyst...
