The study of materials at extreme conditions took a giant leap forward with the discovery of a way to generate super high pressures without using shock waves whose accompanying heat turns solids to liquid. This discovery will allow scientists for the first time to reach static pressure levels exceeding four million atmospheres, a high-pressure environment where new unique compounds could be formed, materials change their chemical and physical properties and metals become insulators. ...

BOLINGBROOK, Ill., May 1, 2012 /PRNewswire/ -- Quantum Foods, LLC, a further-processor of proteins, announced today that it has completed installation of a United States Department of Agriculture (USDA) and United States Food and Drug Administration (FDA)-approved High Pressure Pasteurization System (HPP), which protects against harmful bacteria without affecting a protein's taste, texture, appearance or nutritional value. High Pressure Pasteurization is an all-natural, environmentally...

In the search for superconductors, finding ways to compress hydrogen into a metal has been a point of focus ever since scientists predicted many years ago that electricity would flow, uninhibited, through such a material. Liquid metallic hydrogen is thought to exist in the high-gravity interiors of Jupiter and Saturn. But so far, on Earth, researchers have been unable to use static compression techniques to squeeze hydrogen under high enough pressures to convert it into a metal. Shock-wave...

By Anne M Stark, LLNL By combining high pressure with high temperature, Livermore researchers have created a nanocyrstalline diamond aerogel that could improve the optics for something as big as a telescope or as small as the lenses in eyeglasses. Aerogels are a class of materials that exhibit the lowest density, thermal conductivity, refractive index and sound velocity of any bulk solid. Aerogels are among the most versatile materials available for technical applications due to their many...

Research presented in Albuquerque looks at effect of captured and stored carbon dioxide on minerals The capture and storage of carbon dioxide in deep geologic formations, a strategy for minimizing the impacts of greenhouse gases on global warming, may currently be technologically feasible. But one key question that must be answered is the ability of subsurface materials to maintain their integrity in the presence of supercritical carbon dioxide -- a fluid state in which the gas is condensed...

Scientists have wondered for some time why certain seismic waves travel more quickly through the core-mantle boundary, a thin layer of the Earth's interior that lies between about 1675 and 1800 miles below the surface. Now a new study by Yale University and the University of California, Berkeley sheds light on the mystery by showing how this region behaves under the extreme conditions found so deep in the Earth. The findings, which appeared in the Sept. 24 issue of the journal Science, have...

Using a diamond-anvil cell to recreate the high pressures deep within the earth, researchers at the California Institute of Technology (Caltech) have found unusual properties in an iron-rich magnesium- and iron-oxide mineral that may explain the existence of several ultra-low velocity zones (ULVZs) at the core"“mantle boundary. A paper about their findings was published in a recent issue of Geophysical Research Letters (GRL). ULVZs"”which were first discovered in the early 1990s...

'Most condensed form of energy storage outside of nuclear energy' The world's biggest Roman candle has got nothing on this. Using super-high pressures similar to those found deep in the Earth or on a giant planet, Washington State University researchers have created a compact, never-before-seen material capable of storing vast amounts of energy. "If you think about it, it is the most condensed form of energy storage outside of nuclear energy," says Choong-Shik Yoo, a WSU chemistry professor...

Scientists have used quantum mechanics to reveal that the most common mineral on Earth is relatively uncommon deep within the planet. Using several of the largest supercomputers in the nation, a team of physicists led by Ohio State University has been able to simulate the behavior of silica in a high-temperature, high-pressure form that is particularly difficult to study firsthand in the lab. The resulting discovery -- reported in this week's early online edition of the Proceedings of the...
