It is remarkable but true that we’ve used valves to control the flow of liquids for thousands of years. The city of Pompeii’s water system, for example, utilized quarter-turn style valves that were in principle very similar to those in use today. Cryogenic valves, while unique, are similar to these...

Air Liquide has substantial expertise in designing, fabricating and installing large capacity gas liquefaction and refrigeration systems. Its engineers have completed major cryogenic installations, for example, at CERN and KSTAR (the South Korean Tokamak) and are now working on ITER, providing the project with a centralized helium cryogenic plant and...

The perfect roast for your next cup of joe might just come from liquid nitrogen chilled coffee beans. A team from the University of Bath, working with the Bath coffee shop Colonna & Smalls, reports that chilling roasted beans before grinding results in small uniform coffee grinds. This provides for...

Scientists at NASA's Jet Propulsion Laboratory (JPL) have completed testing of a first-of-its-kind cryocooler for NASA's James Webb Space Telescope. The cooler will chill one of the telescope's four instruments, the Mid-Infrared Instrument (MIRI), a device key to catching faint whispers of light from the very first stars born in...

Scientists from the LIGO Scientific Collaboration have observed gravitational waves for a second time, according to an announcement made on June 15 during the 228th meeting of the American Astronomical Society in San Diego. The detection of the waves—ripples in the fabric of spacetime—was made on Dec. 25 by both...
