This study reports on a facile and economical method for the scalable synthesis of few-layered graphene sheets by the microwave-assisted functionalization. Herein, single-layered and few-layered graphene sheets were produced by dispersion and exfoliation of functionalized graphite in ethylene glycol.
ABSTRACT. Few-layered graphene oxide (GO) was prepared using a fast and energy-saving method by microwave-assisted acid technique. The oxygenated groups existing on the GO surface were determined using UV-Vis, X-ray photoelectron and Fourier-transform infrared spectroscopies.

The development history of tantalum equipment. As early as the 1940s, developed countries already used tantalum to make waste acid treatment equipment. Tantalum is the material of choice for equipment that can handle acids other than hydrofluoric acid, so tantalum plays a significant role in industries that generate large amounts of waste acid.
Using expandable graphite as a starting material A small amount of expandable graphite (grade 1721, Asbury and applying microwave-assisted thermal expansion prior Carbon) was charged into a 1-L beaker and heated for 10 s in a microwave oven. The expansion of graphite was about 150 times its original volume.

Experimental Materials The unmodified isostatic graphite GSI70 (RMC Remacon GmbH, Germany) was used as feed material for the delamination experiments. It has a purity > 99.5% and a median particle size x 50,3 of 15-20 µm (measured by the supplier using a Cilas particle sizer 920). In addition the unmodified natural graphite "GNP6" (RMC
Graphene (/ˈɡræfiːn/) is an allotrope of carbon in the form of a single layer of atoms in a two-dimensional hexagonal lattice in which one atom forms each vertex.It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes.
Microwave heating of solid state carbon-based materials has distinct merits, but they have scarcely been reported, while over 800 papers were published about MAOS in 2007 alone . The purpose of this review is to introduce the microwave heating of carbon-based solid materials, including carbon nanotubes (CNTs), graphite, and others.

In a few works, green compacts, generally prepared using a press or a testing machine, were sintered in a conventional [38, 52, 57, 63, 65, 73, 104] or microwave furnace . The major advantage of the microwave sintering over conventional sintering is that it provides rapid heating, resulting in much finer grain sizes.

2012643.3 Graphite Oxide Reduction:An alternative method for creating single sheets starting from graphite oxide (GO) has beensuggested. Graphite can be oxidized to produced GO and then exfoliated to create stable aqueousdispersions of individual sheets. After deposition, GO may be reduced to graphene eitherchemically or by means of thermal annealing.
Graphene (/ˈɡræf.iːn/) is an allotrope of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes.
We here propose a novel, scalable liquidphase exfoliation method in which the intercalation, expansion, and exfoliation of graphite are achieved all under ambient conditions, not involving any heating or high-temp. treatment. We demonstrate that such room-temp. liq.-phase intercalation and expansion allow graphite flakes to expand up to 1000 times.
