From graphene to graphene oxide: the importance of extended topological defects

Abstract

Graphene oxide (GO) represents a complex family of materials related to graphene: easy to produce in large quantities, easy to process, and convenient to use as a basis for further...

One-Stage Process of Reduction, Fluorination, and Doping with Nitrogen of Graphene Oxide Films

“…Graphene oxide (GO), the interest in which has increased significantly after the experimental demonstration of the possibility of obtaining a two-dimensional graphene crystal, has unique chemical and physical properties, − which are attractive for creating new energy-efficient electronic and optoelectronic devices, such as memristors, , photomemristors, − wide-gap optical sensors, etc. The electronic properties of GO can be controlled by its reduction or impurity doping .…”

Percolation onset and conductivity of nanocomposites assuming an incomplete dispersion of graphene nanosheets in a polymer matrix

“…Graphene has attracted much interest in recent years because it exhibits outstanding levels of stiffness and conductivity. 1–13 The large diameter and small thickness of graphene introduce an early percolation onset in the samples, which can cause high conductivity due to the low filler content. 14,15 However, some obstacles, such as obtaining perfect graphene in high quantity and the identical dispersal of graphene in polymer mediums, limit the observation of its exceptional properties.…”

Exploring adsorption behavior of sulfur and nitrogen compounds on transition metal-doped Cu(100) surfaces: insights from DFT and MD simulations

“…The combination of DFT and ReaxFF provides insights into reactivity and adsorption mechanisms. [45][46][47][48][49][50][51][52][53] We analyze total interaction energies, partial radial distribution functions (RDF), statistical investigations, charge transfer, charge density differences, and changes in work function to elucidate the adsorption mechanisms on the studied surfaces.…”
