Graphene is one of the most attractive two-dimensional nanomaterials widely used as saturable absorber for pulsing laser, owing to its unique non-linear optical responses. However, fabrication and integration graphene into a laser cavity involves complex processes procedures. Mass production graphene-based absorbers requires simplification process with minimum material wastage. Reduced oxide, f...

To construct rapid C3H8 transport pathways in polymer matrix, alkyl chain-functionalized graphene oxide (GO) was prepared via grafting octadecylamine (ODA) molecules and then embedded into polydimethylsiloxane (PDMS) matrix to obtain high-efficiency mixed matrix membranes (MMMs). The incorporation of alkyl chains contributes to lowering the surface energy of GO nanosheets and providing higher a...

An iron oxide/reduced graphene oxide (ION-RGO) nanocomposite has been fabricated to functionalize a low-cost electrochemical nitrite sensor realized by light-scribed reduced (LRGO) electrodes on PET substrate. To enhance the stability and adhesion of electrode, substrate was modified RF oxygen plasma, thin layer cationic poly (diallyl dimethyl ammonium chloride) deposited. Raman spectroscopy sc...

We report an electrochemical oxidation route to tunable C/O ratios in the graphene framework, creating enhanced pseudocapacitance with increasing oxygen content. Controlled surface functionalities on graphene enable a high specific capacitance and negligible electric conductivity loss. A specific capacitance of up to 279 F g(-1) was achieved for the functionalized graphene at a discharge curren...

This article presents the suitable chemical method for preparation of graphene oxide nanosheets. In order to examine the effects of HNO3/H2SO4 ratio on interlayer spacing and its comparison, the oxidation of graphite with HNO3 and H2SO4 in 1:2 and 1:3 volume ratios was done. Based on the reaction time and interlayer spacing, it was found that the optimum results were obtained when reaction was ...
