TL;DR: In this article, a modified Hummers' method was used to prep graphene oxide (GO) sheets with the negative charge and Al powders were coated by hexadecyl trimethyl ammonium bromide (CTAB) to obtain the surface positive charge.

TL;DR: In this paper, the effects of the GNSs content on the microstructures, mechanical properties and fracture mechanisms of the composites were investigated, and it was indicated that the aggregation of GNS contents in the composite is apparent, which seriously separates the matrix and results in low mechanical properties.

TL;DR: In this article, a modified Hummers' method was used to prep graphene oxide with the negative charge and hexadecyl trimethyl ammonium bromide (CTAB) was applied to obtain the surface positive charge.

TL;DR: The proposed electrode is succsefully used to determine LD in human plasma samples and it is potential for use in clinical research and shows good selectivity, reproducibility and stability.

TL;DR: Graphene reinforced copper matrix composites (Gr/Cu) were fabricated by electrostatic self-assembly and powder metallurgy, and the morphology and structure of graphene oxide, graphene oxide-Cu powders and Gr/Cu composites were characterized by scanning electron microscopy, transmission electronic microscopy and X-ray diffraction and Raman spectroscopy, respectively as mentioned in this paper.
