Graphite is a well-known solid lubricant that is well suitable for use in extreme applications in the presence of moisture ≤ 650°C. Previous study found that subjecting graphite to high pressures at ambient temperatures produces a carbon allotrope that has unique properties, which is known as superhard graphite. Artem Oganov, professor at the State University of New York at Stony Brook and his fellow researchers used a novel technique known as Transition Path Sampling to predict that the structure of the carbon allotrope formed at room temperature under pressure is M-carbon. Transition Path Sampling enabled the researchers to evaluate all of the potential transition paths and find the one exhibiting the lowest activation energy. Simulations unequivocally pointed at M-carbon as the kinetically easiest transformation product. The study confirmed that the material has the M-carbon structure.
