Reduced graphene oxide film was synthesized on a glassy carbon electrode by electro reduction of graphene oxide powders in aqueous solution. Then platinum nano particles were deposited on reduced graphene oxide film that was deposited on the glassy carbon electrode via electro reduction of platinum salt. The Physical morphology of the platinum on reduced graphene oxide film was evaluated by sca...

This paper proposed analytical solutions for the buckling analysis of rectangular single-layered graphene sheets under in-plane loading on all edges simply is supported. The characteristic equations of the graphene sheets are derived and the analysis formula is based on the nonlocal Mindlin plate. This theory is considering both the small length scale effects and transverse shear deformation ef...

Abstract As nanoscale reinforcements, the graphene and oxide nanoplates exhibit distinct mechanical physical properties. The determination of effective elasto-plastic behavior nanoplate/ceramic nanocomposites different filling effects nanoplate deserve systematic investigation. In this work, we intend to uncover how affect macroscopic characteristics ceramic matrix what differences in both enha...

A series of novel nanocomposites containing graphene oxide (GO) suitable for stereolithography is presented. Different loads GO are tested, identifying that these materials can be printed with concentrations up to 2.5 wt% GO, presenting improved mechanical properties below 1.0 GO. In this range, the exhibit higher strength and toughness when compared pristine resin. Microscopic analyses materia...

Large scale preparation of single-layer graphene and graphene oxide is of great importance due to their potential applications. We report a simple room temperature method for the exfoliation of graphene oxide using covalent modification of graphene oxide with ferrocene to obtain single-layer graphene oxide sheets. The samples were characterized by FESEM, HRTEM, AFM, EDAX, FT-IR, Raman and Mössb...
