DOE Announces New Lab Consortia to Advance Hydrogen, Fuel Cells

On June 23, the US Department of Energy announced that it will invest up to $100 million over five years in two new DOE National Laboratory-led consortia to advance hydrogen and fuel cell technologies research and development. One consortium will seek to achieve large-scale, affordable electrolyzers which use electricity to...

Rice Physicist Earns Grant to Study Magnetism

On June 23, the Department of Energy’s Office of Basic Energy Sciences awarded Rice University experimental physicist Ming Yi a five-year grant to explore the details of magnetism in two-dimensional materials. She and her colleagues seek to learn the origin of magnetism in bulk materials that are exfoliated for use...

The live "Next Generation of Cryogenics: Tailored for Quantum Technologies" will be presented at 3 p.m. BST/5 p.m. EET on July 2, 2020. It...

Electricity Transmission Reaches Even Higher Intensities at CERN

In CERN’s superconducting equipment testing hall, an innovative transmission line has set a new record for the transport of electricity. The 60-meter long link has transported a total of 54,000 amperes (54 kA, or 27 kA in either direction). The line has been developed for the High-Luminosity LHC (HL-LHC), the...

Scientists Use Pressure to Make Liquid Magnetism Breakthrough

Using two flat-top diamonds and a lot of pressure, scientists at Argonne National Laboratory (CSA CSM) have forced a magnetic crystal into a spin liquid state, which may lead to insights into high temperature superconductivity and quantum computing.

CERN Researchers Create, Study New Exotic Atom at Paul Scherrer Institute

A team of researchers from CERN’s Atomic Spectroscopy and Collisions Using Slow Antiprotons (ASACUSA) collaboration have taken experimental equipment from CERN to the Paul Scherrer Institute near Zurich to create a theoretically predicted, but never before verified, exotic atom and made first measurements of how it absorbs and resonates with...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

What is the temperature range of cryogenics?

Could you please tell me what is the temperature range of cryogenics? In other words, is -100°F considered cryogenic, or does it start lower? Could I expect to see some extended life in D2 stamping dies? What would the recipe be to achieve the desired results using cryogenics?
