We used a multi-anvil apparatus for high-pressure synthesis 1. A pure polycrystalline graphite (99.9995%) rod was found to transform into a transparent, colourless phase in only a few minutes at ...

A diamond is the result of pressing refined, pure graphite under high heat and pressure to mimic natural forces as closely as possible—typically the graphite is transformed inside a “growth ...

Mercury could have a thick underground layer of diamonds, scientists say. Some of the stones may have found their way to the surface, according to a recent study.

Chinese scientists have synthesized a "super diamond" that is 40 percent harder than natural diamonds and exhibits high thermal stability, a breakthrough that could enhance the performance of ...

The next step, Wendy Mao says, is to scale up the method to make larger diamond capsules and to make high-pressure phases of materials that could have practical use. Chemical & Engineering News ...

It used to take the Earth 3 billion years, 2,000-degree temperatures, a little carbon and a lot of pressure to grow a diamond. Now, a new machine can do it in five days.

Diamond is a carbon allotrope, meaning it’s a type of carbon that exists in another form due to its environment (in this case, a lot of time and pressure). Charcoal and graphite are also ...

The diamond layer's high thermal conductivity impacts Mercury's thermal dynamics and magnetic field generation. The diamond layer helps transfer heat from the core to the mantle, affecting ...

Diamond sensors probe matter at high pressures. Now Yao and colleagues have found a solution to this pressure problem that is simple in principle but challenging to engineer. If the upper face of the ...
