Sentences with phrase «times normal atmospheric pressure»

In August 2005, the scientists reported that they created this compound by compressing buckyballs — soccer ball - shaped molecules each made of 60 carbon atoms — at 2,200 degrees C and 200 times normal atmospheric pressure, a process that could lend itself to mass production.
They found that disulfide enters a superconducting state at about -449 degrees Fahrenheit (6.2 Kelvin) at pressures ranging from about 493,000 to about 1,698,000 times normal atmospheric pressure (50 to 172 gigapascals).
The team was able to pinpoint that spin transition was occurring in iron carbonates under about 434,000 times normal atmospheric pressure (44 gigapascals), typical of the lower mantle.
To quantify the energy change, siderite's spin transition was examined using highly sensitive spectroscopic techniques at pressures ranging from zero to about 711,000 times normal atmospheric pressure (72 gigapascals), and also revealed by a visible color change after the transition, indicating rearrangement of electrons.
But recently teams have been able to observe that at pressures of 2 - to - 3.5 million times normal atmospheric pressure it transforms into an unexpected structure consisting of layered sheets, rather than a close - packed metal as had been predicted many years ago.
They showed that at about 40,000 times normal atmospheric pressure (4 gigapascals), NaFe2As2 takes on the collapsed tetragonal structure.
Using a facility maintained by the Geophysical Laboratory at the National Synchrotron Light Source at Brookhaven National Laboratory, the team found the new form to be stable from about 2.2 million times normal atmospheric pressure and about 80 degrees Fahrenheit to at least 3.4 million times atmospheric pressure and about -100 degrees Fahrenheit.
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).
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.
