Not exact matches

To generate an accurate picture of the temperature profile within the Earth's centre, scientists can look at the melting point of iron at different pressures in the laboratory, using a diamond anvil cell to compress speck - sized samples to pressures of several million atmospheres, and powerful laser beams to heat them to 4000 or even 5000 degrees Celsius.

This is an illustration of Ar (H2) 2 in the diamond anvil cell.

But rather than natural diamond, Silvera and Dias used two small pieces of carefully polished synthetic diamond which were then treated to make them even tougher and then mounted opposite each other in a device known as a diamond anvil cell.

In the laboratory, we're using diamond anvils to create high pressures and temperatures, to study the effects of materials in the core.

And the way this researcher, Kei Hirose, who wrote about this — he's at the Tokyo Institute of Technology — found out about this mineral as he tried to replicate the conditions that's far deep below the Earth; and [he] used a diamond anvil cell and learned more about this super dense, heretofore unexpected material around the inner core.

In a lab at Ohio State, the researchers compress different minerals that are common to the mantle and subject them to high pressures and temperatures using a diamond anvil cell — a device that squeezes a tiny sample of material between two diamonds and heats it with a laser — to simulate conditions in the deep Earth.
