Graphene oxide (GO) has enormous potential to improve properties of cementitious materials. Well dispersed GO in hardened cement matrix could be more effective in strengthening concrete compared to aggregated GO. While GO agglomeration is somewhat inevitable due to its fine nature, the degree of ...
Functionalized graphene oxide (GO)/SiO2nanocomposites (FGS) was successfully fabricated by two steps; the first one was the combustion of RHP in covered crucible inside stainless steel autoclave at three different temperature, 400, 500, and 600 °C at 1 h for obtaining ash RHA1, RHA2, and ...
EXFOLIATION OF GRAPHENE OXIDE NANOSHEETS FROM PENCIL LEAD AND IN SITU PREPARATION OF GOLD NANOPARTICLES ON GRAPHENE OXIDE NANOSHEETS. This work reports the low-cost exfoliation of graphene oxide (GO) from pencil lead using modified Hummer's method. The gold nanoparticles (AuNPs) supported... BORUAH...

To synthesize monodisperse palladium nanoparticles dispersed on reduced graphene oxide (RGO) sheets, we have developed an easy and scalable solvothermal reduction method from an organic solution system. The RGO-supported palladium nanoparticles with a diameter of 3.8 nm are synthesized in N-methyl-2...
We have developed a facile and scalable chemical reduction method assisted by microwave irradiation for the synthesis of chemically converted graphene sheets and metal nanoparticles dispersed on the graphene sheets. The method allows rap... HMA Hassan,V Abdelsayed,AERS Khder,... - 《Journal of Mate...
The PDDA-rGO nanosheets could be modified with Ag nanoparticles (AgNPs) by direct adsorption of preformed, negatively charged AgNPs. It was found that the AgNPs were distributed uniformly on the PDDA-rGO nanosheets and the obtained PDDA-rGO/AgNPs nanocomposites exhibited prominent electrocatalytic ...
First isolated in the form of graphene oxide (GO) by chemist Benjamin C. Brodie, the material was produced by the addition of potassium chlorate to a slurry of graphite in fuming nitric acid [2]. However, methods to effectively derive graphene in monolayers did not prove successful until the...
This review focuses on the recent advances in the synthesis of graphene quantum dots (GQDs) and their applications in drug delivery. To give a brief understanding about the preparation of GQDs, recent advances in methods of GQDs synthesis are first prese
We report a simple new approach for green preparation of gallic acid supported reduced graphene oxide encapsulated gold nanoparticles (GA-RGO/AuNPs) via one-pot hydrothermal method. The as-prepared composites were successfully characterized by using Fourier transform infrared spectroscopy (FTIR), Raman ...
