Crossover from gas-like to liquid-like molecular diffusion in a simple supercritical fluid [PDF]

Nature Communications
According to textbooks, no physical observable can be discerned allowing to distinguish a liquid from a gas beyond the critical point. Yet, several proposals have been put forward challenging this view and various transition boundaries between a gas-like

Highly crystalline graphite-like carbon from wood via low-temperature catalytic graphitization

Carbon Trends, 2022
In this study, we investigated the synthesis of wood-sawdust-derived high-crystalline graphite-like carbon. The sawdust was first impregnated with Fe and semi-carbonized by a hydrothermal treatment (HT) at 250°C, followed by the second carbonization ...
