The first phase of this work aims to use the right additive nano-fillers choices, such as exfoliated Graphite (ExG), increasing mechanical, electrical, and thermal performances. In work, we are interested in quantifying effect particles' size on a polymer matrix's performance. For this, three sets polymers filled with Graphite, characterized by particle sizes, called meshes 50, 100, 150, were i...

A simple and efficient method was introduced for the high-conversion preparation of graphene oxide (GO) from large graphite flakes (average flake size1⁄4100 μm) using a simplified Hummer's method. Natural reducing agents such as lemon juice and vinegar were compared with hydrazine (N2H4) as potential reducing agents. Graphene was prepared by chemical reduction of GO because this method was low ...

One of the enduring challenges in graphene research and applications is the extreme sensitivity of its charge carriers to external perturbations, especially those introduced by the substrate. The best available substrates to date, graphite and hexagonal boron nitride (h-BN), still pose limitations: graphite being metallic does not allow gating, while both h-BN and graphite, having lattice struc...

This paper presents an investigation on energy absorption characteristics of nano-reinforced panels, laminated face sheets and sandwich composites in high velocity ballistic and low velocity punch-shear experiments. The vinyl ester panels were reinforced with 1.25 and 2.5 wt. percent nanoclay and exfoliated graphite platelets. Three different face sheets were manufactured with E-glass, Owens Co...

Graphene, a flat monolayer of carbon atoms tightly packed into a two-dimensional honeycomb lattice, has attracted a great deal of attention in recent years for potential applications in many technological fields, such as nanoelectronics, nanocomposites, and hydrogen supercapacitors. One possible route to harnessing these properties would be to incorporate graphene sheets into composite material...

The preparation of graphene/apatite and graphene oxide/apatite hybrid nanocomposites has recently attracted great attention in the biomaterial community. sitting drop vapor diffusion technique been assessed as a preparative method for such this work. employed to induce heterogeneous nucleation growth calcium phosphate presence exfoliated commercial oxide flakes, both labeled with L-Alanine.
