Graphite has a stacked planar sp 2-hybridized C 6 ring structure, displaying a polymorphism
with rhombohedral, hexagonal, and turbostratic. Based on its structure-property relationship …

The transition to a low-carbon economy will be material-intensive. Production of these
materials (from mining to manufacturing) incurs environmental costs that vary widely …

The structure of onset phase of coal derived natural graphite (CDNG for short), semi-
graphite, and CDNG subjected to different metamorphic grade were investigated using XRD …

Estimates of the time at which life arose on Earth make use of two types of evidence. First,
astrophysical and geophysical studies provide a timescale for the formation of Earth and the …

Three types of thermosetting heterocyclic phenolic resins (either oxygen-, nitrogen-or sulfur-
doped) impregnated with FeCl 3 were pyrolyzed in the temperature range of 750–1150° C to …

Graphite samples from several mines (Austria, Brazil, China, Madagascar, Mozambique,
Norway, Russia, Sri Lanka and Ukraine) were investigated by reflectance measurements, X …

The clean energy transition will require a vast increase in metal supply, yet new mineral
deposit discoveries are declining, due in part to challenges associated with exploring under …

Carbon materials are among the most commonly used components of supercapacitor
electrodes. Particularly, active carbons are recognized as cheap, available, and easily …

Current models for the formation of natural diamond involve either oxidation of a methane-
bearing fluid by reaction with oxidized mantle, or reduction of a carbonate-bearing fluid (or …
