Scientists have used a new method to precisely simulate the phase transition from graphite to diamond for the first time. Instead of happening concerted, all at once, the conversion evidently takes ...

Watch this video to understand the different properties of diamond and graphite. The rigid network of carbon atoms, held together by strong covalent bonds, makes diamond very hard. This makes it ...

(Phys.org)—Researchers have finally answered a question that has eluded scientists for years: when exposed to moderately high pressures, why does graphite turn into hexagonal diamond (also called ...

The phase transition from graphite to diamond is an appealing object of study because of many fundamental and also, practical reasons. The out-of-plane distortions required for the transition are a ...

Converting graphite into diamond has been a long held dream of alchemists the world over. In the modern era, materials scientists have puzzled over this process because it’s hard to work out why the ...

This illustration depicts a new technique that uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips.

Molten carbon can crystallize into diamond or graphite, but it has been difficult to study this process. New simulations show that graphite can sometimes "hijack" the pathway that would lead to ...

Since graphite—the dark material used in regular old pencils—and diamonds are both made from carbon, it’s technically feasible to turn the former into the latter. You just need to apply a little ...

A team of researchers has for the first time observed and recorded the creation of hexagonal diamond under shock compression, revealing crucial details about how it is formed. The discovery could help ...

A team of scientists from two universities in China have synthesized a material harder than diamond in the laboratory. When carbon is subjected to extreme heat and pressure within the Earth, it can ...
