BAND-STRUCTURESPECTROSCOPYXPSC KVV Auger electron spectra of highly oriented pyrolytic graphite (HOPG) (at different emission angles) and of quaterphenyl, fullerenes C60, single- and multi-wall carbon nanotubes (MWNT) have been studied. The interpretation of HOPG spectra is based on the angular ...
2.2. Separation of electrode from used ZCB and treatment The carbon electrode rod was taken out from discharged battery and was washed with very dil. HCl (20%). The electrode was then boiled in millipore water for about 5 min to remove any remaining impurities. The graphite electrode so obta...
A cosmic and solar radiation shielding structure that also has structural attributes is comprised of three layers. The first layer is 30-42 percent by volume of ultra-high molecular weight (UHMW) polyethylene fibers, 18-30 percent by volume of graphite fibers, and a remaining percent by volume...

Structure, thermodynamics, and electronic properties are predicted for a new low energy phase of carbon which contains planar sheets equally occupied bysp2andspcarbon atoms. The isolated planar sheets have the same planar symmetry as do the layers in graphite (p6m) and can be formally viewed as...
With some qualitative analogy with graphite-diamond (where of course the density jump is a much larger 55% ) these large barriers and the associated nucleation costs might permit to the layered phases to survive in a metastable state, once recovered at ambient pressure and low temperatures. ...
The electronic structure of the intercalated graphite compounds XC 6 (X = Ca, Sr, Ba, Yb, and La) has been studied using the linearized augmented plane-wave method. It has been found that the electronic structure of the carbon layers in these compounds is qualitatively different from a two...

Graphene is a two-dimensional planar structure of s[Math Processing Error]p2 hybridized carbon atoms1 arranged in a honeycomb crystal lattice2 with an inter-layer spacing of [Math Processing Error]∼ 3.35 Å. Graphite crystals, nanotubes, and fullerenes can be formed from graphene by stacking...
The layers can be very simple, as in the case of graphite and boron nitride, being only one atom thick, or more complicated, such as in clay minerals, where the layers are up to seven atoms thick. Those layers can be neutral, like in graphite and magnesium hydroxide, negatively charged ...
