Cost-effective storage remains one of the greatest challenges facing adoption renewable energy generation. Herein we present a cost-effective aqueous rechargeable battery based on MoS2. Increased discharge capacities are achieved by liquid-phase exfoliation, resulting in 105% increase capacity and prolonged lithiation plateau. Contributing evidence is provided High Resolution TEM investigation ...

We demonstrated the effect of superparamagnetic Fe3O4 nanoparticles on Schottky barriers of graphene, in which the Fe3O4 nanoparticles were fabricated by a hydrothermal method and the single-layer graphene sheets were mechanically exfoliated from Kish graphite. The Fe3O4 nanoparticles were superparamagnetic with the saturation magnetic moment of about 32 emu/g at room temperature. We have found...

An exfoliated graphite-polystyrene composite electrode was evaluated as an alternative electrode in the oxidation and the determination of oxalic acid in 0.1 M Na2SO4 supporting electrolyte. Using CV, LSV, CA procedures, linear dependences I vs. C were obtained in the concentrations range of oxalic acid between 0.5 to 3 mM, with LOD =0.05 mM, and recovery degree of 98%, without need of surface ...

Polymer nanocomposites with engineered electrical properties can be made by tuning the fabrication method, processing conditions and filler’s geometric and physical properties. This work focuses on investigating the effect of filler’s geometry (aspect ratio and shape), intrinsic electrical conductivity, alignment and dispersion within the polymer, and polymer crystallinity, on the percolation t...

This study compares the effect of addition two types lubricants on dry sliding behavior a simplified Cu-free phenolic resin-based composite material. The were commercial graphite and exfoliated graphitic carbon nitride (codenamed: TEX6). particles rounded ‘flaky’ character. TEX6 not only flaky, but also irregular in shape, ‘fluffy’. Both added individually basic formulation subjected to tests p...
