We report the development of a highly efficient photocatalytic system by immobilizing high-quality CdS quantum dots and dendritic Pt nanocrystals on thiol-functionalized graphene substrates. We have demonstrated that the use of QDs with compact sizes leads to a dramatically enhanced performance in comparison with their bulk counterparts. Our design allows for systematic examination of the impac...

With the thickness of only a single atomic layer, graphene displays many interesting surface properties. A general observation is that wrinkles are formed on graphene oxide (GO) when it is dried in the presence of adsorbed inorganic nanoparticles. In this case, evaporation induced wrinkling is not an elastic deformation but is permanent. Understanding the nanoscale force of wrinkle formation is...

a organic-solution-processable functionalized-graphene (spfgraphene) material has been studied on pre-concentration and determination of trace mo(ii)ions. in this process, the effects of ph solution, elution conditions on pre-concentration of trace mo(ii) were studied and the effect of interfering ions was also investigated. a selective method for the fast determination of trace amounts of mo (...

Abstract Graphene-oxide (GO) has been recognized as an excellent lubrication material owing to its two-dimensional structure and weak interlayer interactions. However, the functional groups of GO that can contribute anti-friction, anti-wear, superlubricity are yet be elucidated. Hence, further improvement in GO-family materials tribology fields is impeded. In this study, macroscale with a coeff...

Nowadays, the excessive and uncontrolled discharge of chemicals are imposing major health threats. The demands for clean safe water amplifies need to develop improved technologies environmental contaminant removal. Considering limitations conventional methods contaminants removal, we have prepared magnetic iron oxide nanoparticles functionalised with reduced graphene as a potential material pol...
