A sudden release of pressure allowed a copper-based compound to superconduct at the highest temperature yet for atmospheric ...

Researchers have produced nearly pure hexagonal diamond, a material long theorized to be harder than conventional diamond, by ...

An international research team has produced a bulk, millimeter-scale hexagonal diamond in the laboratory, a crystal variant long theorized to rival or exceed the hardness of the cubic diamonds found ...

Numerical simulations of heat transport in diamond anvil cells reveal a possibility for absolute measurements of specific heat via high-frequency modulation calorimetry. Such experiments could reveal ...

A new diamond-anvil cell apparatus for in situ synchrotron X-ray diffraction measurements of liquids and glasses, at pressures from ambient to 5 GPa and temperatures from ambient to 1300 K, is ...

In a high-pressure lab experiment, scientists accidentally created a new compound called gold hydride. This particular hydride formed when thin gold foil met dense hydrogen at pressures hundreds of ...

Researchers at KRISS observed water’s rapid freeze–melt cycles under ultrahigh pressure and discovered Ice XXI, the first new ice phase found in decades. Using advanced high-pressure tech and ...

Using a dynamic diamond anvil cell and the European XFEL, scientists captured water crystallizing at 2 GPa in microseconds, revealing multiple freezing pathways via Ice XXI The Korea Research ...

We usually think of ice as just frozen water. It is simple, solid, and cold. But water is a master of disguise. With just two atoms, hydrogen and oxygen, it can freeze into more than 20 different ...

Scientists have demonstrated that supercompressed water transforms into ice VI at room temperature through multiple freezing-melting pathways, which occur via a previously unknown form of metastable ...
