Laminar structure membranes assembled with two-dimensional materials, such as graphene oxide (GO), have attracted wide attention from researchers in waste water treatment. However, it is still a challenge to obtain high-performance membranes by precisely controlling the channel of water permeation. In...

An in situ strategy for fabrication of reduced graphene oxide/fused silica (rGO/FS) composites using 3-aminopropyltriethoxysilane as surfactant is reported. GO nanosheets were bound to FS particles by an electrostatic assembly between ultra thin negatively charged GO sheets and positively charged amino...
simple method. Chemical activation of rice husk ash as a precursor of carbon and SiO2in the composite yielded a facile, efficient, and scalable technique for manufacturing functionalized graphene oxide with silica (FGS) in the current work. As a catalyst for RHA activation, KOH is a strong ...
However, traditionally mechanical mixing of Si and graphene cannot realize uniform distribution of Si particles on the graphene sheets, which would largely weaken the effectiveness of the graphene in the composite. In this work, nano-Si/reduced graphene oxide porous composite (p Si/rGO) has been ...
Preparation and characterization of open-tubular capillary column modified with graphene oxide nanosheets for the separation of small organic molecules A novel coated capillary was prepared by immobilizing graphene oxide (GO) on the fused-silica capillary (75 mu m i.d.) which was derivatized by 3-...
As an attractive solution to screen printed electrodes, we present our results related to fabrication of a well-organized, interleaved, freestanding, large-area composite anode consisting of SiOC particles supported by crumpled reduced graphene oxide matrix. The electrode delivers higher volumetric capacity...
In this study, pure and NH2-functionalized graphene oxide (GO) nanosheets have been added to the cement mortar with different weight percents (0.05, 0.10, 0.15, 0.20 and 0.25 wt%). In addition, the effects of functionalizing GO on the microstructure and mechanical properties (flexural/compressi...
Graphene oxide (GO) is a highly oxidized form of chemically modified graphene that consists of single atom thick layer of graphene sheets with carboxylic acid, epoxide and hydroxyl groups in the plane. From: Journal of Controlled Release, 2014 ...
