Researchers placed a speck of iron between two small conical diamonds and applied laser - beam heat and 200 gigapascals of pressure.

Not exact matches

The recoil from this tiny plume creates tremendous pressures in the remaining foil — up to 300 gigapascals, which is three million times the atmospheric pressure around us and comparable to the 350 - gigapascal pressure at the center of the Earth, Nagler said.

The pressures were high, up to 5 GigaPascals (50,000 times the Earth's atmospheric pressure), which is the sort of pressure where you can form diamonds.

And indeed, when the team subjected an alloy of aluminum called aluminum 7075 (which contains small percentages of magnesium and zinc) to the process, the metal attained a strength of 1 gigapascal, the researchers report in the current issue of Nature Communications.

Using JUQUEEN, the team was able to extend its investigation well beyond the experimentally achieved 172 Gigapascals, corresponding to 1.72 million times the Earth's atmospheric pressure, or roughly the amount of pressure the Eiffel Tower would apply by pressing down on the tip of a person's finger.

The team found that the final product (LaPt5As) was non-superconducting at a pressure of five gigapascals (GPa)(equivalent to 50,000 bars of pressure), but became superconducting at 10 GPa, only to return to a non-superconductive state at 15 GPa.

The pair managed to turn hydrogen metallic at a pressure of 495 gigapascals, well beyond the 360 GPa of Earth's core (Science, DOI: 10.1126 / science.eaal1579).

This happens at pressures around 600,000 times Earth's atmosphere (60 gigapascals), which would be comparable to the pressure conditions found in the interior of an icy - cored planet, like Neptune or Uranus.

But these cores formed under the weight of their planets» outer layers, under pressures of around 500 gigapascals — 5 million times atmospheric pressure on Earth — and typical temperatures of about 6,000 kelvin.

The CNT films made using the microcombing technique had more than twice the tensile strength of the uncombed CNT films — greater than 3 gigapascals for the microcombed material, versus less than 1.5 gigapascals for the uncombed material.

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.

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.

That's interesting enough on its own, but it has much bigger implications — the team calculated that these diamonds could only have formed under pressure of more than 20 gigapascals.

They subjected mixtures of Na - Si to various pressures and temperature regimes and found a type of clathrate, Na8Si46, that formed at pressures ranging from 20,000 to 60,000 times atmospheric pressure (2 to 6 gigapascals, GPa) and temperatures of 1160 to 1520 °F (900 to 1100 K).
