This paper is part of a wider study on the effect of the crystallinity of the parent graphite on the structure and properties of the graphene oxides (GOs) and partially reduced graphene oxides (RGOs). Specifically, graphene oxides obtained from two graphites of different crystallinity by using ...
(1) Graphitization degree: As the graphitization degree of carbon material increases, its activity to gas decreases. The higher the final heat treatment temperature of the carbon material, the higher the temperature at which it starts to oxidize, so the initial oxidation temperature of graphite prod...
Graphene is a single-atom-thick sheet of sp(2) hybridized carbon atoms that are packed in a hexagonal honeycomb crystalline structure. Graphene is the fundamental building block of all sp(2) carbon materials including single-walled carbon nanotubes, mutliwalled carbon nanotubes, and graphite and ...

The second band is located toroidally upstream of the first along the graphite sample slot and has globular structure. The coating thickness in this band varies from 18 μm on the first band boundary to 10 μm on the silicon collector edge. The third band of background deposition is located...
Of greatest concern for long-term disposal of irradiated graphite is carbon-14 (C-14), with a half-life of 5730 years. Study of irradiated graphite from nuclear reactors indicates C-14 is concentrated on the outer 5 mm of the graphite structure. The aim of the research described here is ...

Optimization of the facet structure of transition-metal catalysts applied to the oxygen reduction reaction While much effort has been devoted to understanding how nanoparticle morphology can be leveraged to improve catalytic activity, engineering their microstructure from first principles to this end has re...
Adhesive and dense rhenium coatings were fabricated on graphite substrates by thermal decomposition of Re 2(CO) 10. The rhenium coatings possessed columnar grains at deposition temperatures above 600 °C and fine fibrous grains below 500 °C. The degree of crystallinity increased as the deposition ...
The authors noted that the extraction efficiency of these phenols depended on factors such as pH levels, the ratio of phases, salt contents, and the structure of the IL used. For instance, around 82% extraction efficiency was achieved at pH 9 using 1-butyl-3-(8-hydroxyoctyl) imidazolium ...
