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...

Bluefors, Physics World Offer Cryogenics in Quantum Technologies Webinar

Bluefors, a Finnish cryogenics company focused on the quantum computing industry, and Physics World are jointly presenting a free quantum computing-centered webinar open to the public. 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...

You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

Seeking alloy that keeps elastic property down to 10K

I am looking for a metal (alloy) that supports high temperatures (at least 1600K) and keeps its elastic property at low temperatures down to 10K. Rhenium is a good one because it does not become brittle. But it is quite expensive. Pure tungsten and molybdenum enter in the brittle regime...

Searching for a freezer that does not need electricity

I’m student of University of Barcelona. We do technical cryogenic research and we are searching for a cryogenic portable freezer that does not need electricity. We can’t find any company that offers something like this. The product we are looking for is the typical portable freezer for food or drinks...
