Sentences with phrase «using diamond anvil cells»

Using diamond anvil cells (DAC), the team applied 2.5 GPa of pressure (25 thousand atmospheres) to pre-compress water into the room - temperature ice VII, a cubic crystalline form that is different from «ice - cube» hexagonal ice, in addition to being 60 percent denser than water at ambient pressure and temperature.

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.

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.

Not exact matches

The team brought the argon - doped hydrogen up to 3.5 million times normal atmospheric pressure — or 358 gigapascals — inside a diamond anvil cell and observed its structural changes using advanced spectroscopic tools.

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.

Using a diamond anvil pressure cell and laser heating — to duplicate the mantle's unimaginable pressure and heat — they tested their recipe of bridgmanite with a pinch of ferric iron.

They created Ti3N4 in a cubic crystalline phase using a laser - heated diamond anvil cell, which was brought to about 740,000 times normal atmospheric pressure (74 gigapascals) and about 2,200 degrees Celsius (2,500 kelvin).

To test this idea, the team used sophisticated tools at Argonne National Laboratory to examine the propagation of seismic waves through samples of iron peroxide that were created under deep - Earth - mimicking pressure and temperature conditions employing a laser - heated diamond anvil cell.

We use high pressure technique based on diamond anvil cells to understand the dynamics and structure of materials, especially interfacial phenomenons.

The technique uses high - brilliance circularly polarized X-rays to probe the magnetic state of magnetite as a diamond anvil cell subjects a sample to many hundreds of thousands of atmospheres.
