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 — ...

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

Nanostructured diamond capsules (NDCs) with high-pressure argon nanodomains embedded in the matrix. (Courtesy: Charles Zeng) High pressures dramatically change the properties of materials, sometimes ...

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 ...

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 ...

A device made using a tiny bead floating in a beam of light can measure extremely small pressures and could help find a ...

Demonstrates basic principles of water, including surface tension, pressure, and buoyancy. It shows how water can hold more than its brim due to surface tension, how pressure increases with depth, and ...

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 ...

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 ...

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 ...
