Most notably, the chemical structure of GO predicts that GO should exhibit many soft material properties. GO can be viewed as a 2D polymer consisting of covalently tethered oxygen-derivatized carbon atoms (Figure 14.1(c), right). GO and graphite oxide have long been viewed to be hydrophilic ...
The structure of graphene oxide is still unclear due to its complicated non-stoichiometric nature. There are different kinds of oxygen species and bondings to carbon in graphene layer, such as epoxy, hydroxyl, carbonyl, carboxylic groups (Fig. 3.149). Sign in to download full-size image Figure...
Graphene oxide is a promising material for molecular separation technologies. Here, the authors propose a realistic staggered stacking structure that plays a crucial role in H/D recognition in water adsorption, as well as high mobilities of water. ...
Graphene oxide is highly desired for printing electronics, catalysis, energy storage, separation membranes, biomedicine, and composites. However, the present synthesis methods depend on the reactions of graphite with mixed strong oxidants, which suffer from explosion risk, serious environmental pollution, ...
The key functionalities of the oxide layer are two-fold: First, it electrically insulates graphene from Si so that only the graphene channel is examined. Second, it creates an energy barrier between graphene and Si, which prevents charge transfers that occur in the traditional hybrid structure [...
A 3D-printed concrete structure created by RMIT Engineering students. Credit: Jonathan Tran Engineers have added graphene oxide to cement mixture to make stronger 3D-printed concrete that is easier to print, paving the way to create potential "smart" walls that can monitor cracks. ...
Graphene oxide (GO) and carboxyl graphene (CXYG) nanoplatelet suspensions were obtained in water and culture medium. Size frequency distribution of the suspensions was determined by means of dynamic light scattering. Height, lateral dimension and shape of the nanoplatelets were determined using atomic ...

Tselykovskiy Department of Micro- and Nanoelectronics, National Research Nuclear University MEPHI, 115409, Kashirskoe sh., 31, Moscow, Russia, gizebrev@mephi.ru Abstract We study impact of the near-interfacial oxide traps on the C-V and I-V characteristics of graphene gated structures. Methods...
During the hydrothermal reaction, PF was induced to form on the surface of graphene oxide. Thus, the as-prepared sample presented a thin layered structure with some micropores and defects after thermal treatment. Benefiting from unique nanostructure, the obtained PF-derived carbon demonstrated a ...
