Carbon compounds form the basis of all life on Earth and the carbon-nitrogen cycle provides some of the energy produced by the Sun and other stars.
Moreover, carbon has the highest melting/sublimation point of all elements.
The journal is published six times a year, and we also publish conference proceedings and monographs on topics related to our fields of interest.
Atomic weight 12.01, Atomic Number 6, Melting Point 3550 C, Boiling Point 4,827 C.Typically, this will involve examining spores and pollen to examine when land was cleared of scrub and trees in the Neolithic Revolution to make way for crops.This is like trying to dispute telescopic observations of the moon, by pointing a microscope at it.At atmospheric pressure it has no actual melting point as its triple point is at 10 MPa (100 bar) so it sublimates above 4000 K.Thus it remains solid at higher temperatures than the highest melting point metals like tungsten or rhenium, regardless of its allotropic form.
