Abstract:

Graphene derivatives have demonstrated high potential for various applications, including environmental ones. In this work, graphene oxide nano-sheets were obtained by utilizing a simple chemical method and were tested for water treatment applications. The pollutant adsorption ability of the produced GO was adjusted through a proper oxidation treatment of the graphene nano-sheets. The GO treatment time was systematically varied to control the oxidation level of the graphene nano-sheets and was found to considerably affect the GO’s properties and performance in removing methylene blue.

Abstract In this study, we present a one-pot approach for the large-scale synthesis of multilayer to few-layer graphene nanosheets in an aqueous medium that is cost-effective, environmentally friendly, high-yielding, and simple. This electrochemical exfoliation method produces low defect and high yield graphene nanosheet products and is more efficient than chemical exfoliation methods. Two highly oriented pyrolytic graphite plates (HOPG) are utilized as the anode and cathode in this method, which also incorporates two electrode geometry configurations.

Abstract:

The use of a nanostructured graphene-zirconia composite will allow the development of new materials with improved performance properties and a high functionality. This work covers a stepwise study related to the creation of a nanostructured composite based on ZrO2 and graphene. A composite was prepared using two suspensions: nano-zirconia obtained by sol-gel synthesis and oxygen-free graphene obtained sonochemically. The morphology of oxygen-free graphene sheets, phase composition and the morphology of a zirconia powder, and the morphology of the synthesized composite were studied. The effect

A technologically promising method for obtaining nanostructured graphene/ZrO2 has been proposed. Its main idea is to use suspensions of graphene and nano-ZrO2 and create conditions for the interaction of graphene sheets and ZrO2 crystallites to form a hybrid nanostructured powder without the formation of new chemical bonds. The oxygen-free graphene sheets with thickness of several nanometers were obtained by sonochemical method in N,N-dimethyloctylamine-aqua emulsion.

In the present research, imperfect graphene sheets were generated and their vibrational property was studied via finite element analysis. The effect of vacant sites in the arrangement of these nano-structures was examined.

Abstract:

Heat conducting gel sheets were fabricated with graphene nano-particles (GNPs) filler which was prepared by ball-milling method. The thermal conductivity of GNPs gel sheets (GNPs-GS) with 10 wt.% reaching 0.38 W/(m⋅K) at [Formula: see text] increased by 90% compared with the pure gel sheets (Pure-GS). The conduction of heat-sink device which was made of GNPs-GS with 10 wt.% is much faster than the one which was made of Pure-GS. FE-SEM images show that the GNPs are layered and uniformly distributed in the matrix, which demonstrated the actual exfoliation of GNPs in the process of ball-milling.

Abstract:

Nano-Al2O3 particles and graphene oxide (GO) nanosheets were modified by 3-aminopropyltriethoxysilane (KH550), and then dispersed in epoxy resin, and finally modified-Al2O3/epoxy, modified-GO/epoxy and modified-Al2O3@GO/epoxy composite coatings were prepared on steel sheets by the scraping stick method.

Abstract:

Copper-graphene nano composite is prepared with 0.25,0.50,0.75,1.00,1.25 and 1.50 wt.% graphene nano sheets. Powder metallurgy technique is used for the preparation process. In which copper powder is mechanically milled with nano graphene sheet by 10: 1 ball to powder ratio, and 400 rpm for 12 hr. milling time. The mixtures are compacted by a uniaxial press under 700 Mpa pressure. The compacted samples are sintered under controlled atmosphere at 950 oC for 1.5 hrs. A comparison between methanol & hexane as a process controlling agent is established. In which Cu-GNSs are mixed with methanol

Abstract:

Graphite is a based on three-domination functionalized carbon content made up of millions of graphene layers. In this study, graphene oxide (GO) and graphene oxide\Ag nanocomposites (GO-Ag) have been synthesized in a single layer using a modified Hummer method. The morphology and structural characteristics of GO and GO-Ag nanocomposites were investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmitted electron microscopy (TEM), and Raman spectroscopy. The results of TEM indicated the single and double layer structure with thickness of 4-6 nm for GO

Abstract:

Since the discovery of graphene in 2004 [1], it has been considered a “Wonder” material with lots of potential due to its attractive properties. Owing to such properties, graphene is theoretically expected to have an electrochemical double layer capacitance of 550 F/g [2]. However, due to the high cost and difficulty of producing and handling single sheets of graphene, the presence of graphene in the market was hindered. Luckily, many methods were devised to synthesize graphene-like materials that would be easier and cheaper to produce. Unfortunately such methods end up producing reduced Graph

Abstract:

<em>Graphene, a material with remarkable properties due to its two-dimensional structure, electronic structure, and lattice symmetry, has numerous applications in nano-electronics, photovoltaics, and environmental or catalysis. Its mechanical strength, elasticity, and out-of-plane flexibility make it ideal for producing pseudo magnetism and other precise electronic structure modifications. However, the 2D to 3D transition has made it challenging to maintain and improve its 2D qualities. Two primary approaches have been explored: synthesizing precursors in graphene flakes and constructing struc
