Anisotropic thermal conductivity and permeability of compacted expanded natural graphite [PDF]
, 2010 The anisotropic thermal conductivities and permeabilities are investigated for discs and plates of compacted expanded natural graphite. The measuring directions of heat conductivity and permeability are both parallel and perpendicular to the pressing ...

Avant-Garde Polymer and Nano-Graphite-Derived Nanocomposites—Versatility and Implications
C, 2023 Graphite (stacked graphene layers) has been modified in several ways to enhance its potential properties/utilities. One approach is to convert graphite into a unique ‘nano-graphite’ form.

International Journal of Electrochemical Science, 2013 High quality reduced graphene oxide (rGO) nanosheets were prepared from natural graphite through oxidation followed by solvothermal reduction method. The morphology, structure and composition of graphene oxide (GO) and rGO were characterized by scanning ...

The Astrophysical Journal, 2016 ABSTRACT Laboratory measurements are used to constrain the dielectric tensor for graphite, from microwave to X-ray frequencies. The dielectric tensor is strongly anisotropic even at X-ray energies. The discrete dipole approximation is employed for accurate calculations of absorption and scattering by single-crystal graphite spheres and ...

Ultraviolet-visible spectroscopy of graphene oxides
AIP Advances, 2012 Dispersions of few-layer (1-3 layers), multi-layer (4-10 layers) and thick-layer (>10 layers) graphene oxide (GO) were prepared by a modified Hummers method with different mass ratios of KMnO4 to graphite.
