To test the Standard Model of particle physics, scientists often collide particles using gigantic underground rings. In a similar fashion, high-pressure physicists compress materials to ever greater ...

Air molecules colliding with a surface cause atmospheric pressure. Atmospheric pressure at sea level is about 101,000 Pa (101 kPa) but just 27,000 Pa (27 kPa) at the cruising altitude of a passenger ...

Pressure is one of the fundamental thermodynamic variables. It affects intermolecular interactions and interatomic properties. Under extreme conditions such as high pressure, materials exhibit ...

Note: Articles may be assigned to more than one subject area, as a result the sum of the subject research outputs may not equal the overall research outputs. Actionable insights into research ...

Researchers at the University of Edinburgh have discovered new high-pressure structures in the elements tellurium and selenium. This information could allow scientists to understand more about the ...

Have you ever heard of metallic hydrogen? Probably not, because it has only ever existed in theory. Harvard scientists have recently created metallic hydrogen from applying extremely high pressure to ...

For decades, scientists quested after a room-temperature superconductor. Now that they’ve finally found one, the hunt is on for an even better material. Until last year, all known superconductors — ...

Hydrogen, the most abundant element in the universe, is found as a gas in our atmosphere. In 1935, Eugene Wigner and Hillard Bell Huntington put out a theory that at high enough pressures, hydrogen ...

Gold has a reputation for being one of the most stable, predictable elements in the periodic table, but under crushing pressures and searing temperatures it turns out to be anything but simple. By ...

This video explains how gas pressure changes as volume changes. Pressure and volume are inversely proportional. That means if the volume of a gas doubles, its pressure halves for a fixed amount of gas ...
