High Temperature Superconductor (HTS) current leads are the components that transmit the large currents from room-temperature power supplies to very low-temperature superconducting coils.
About half the world's plant species are estimated to be under threat of extinction, and Australia is home to 14 percent of them. It is now hoped a cryogenic storage unit can protect Australia's native plants forever.
The first US flag vessel to be operated on liquefied natural gas uses valves supplied by Bestobell Valves (CSA CSM). Globe and check valves were supplied as part of the LNGPac fuel system through the company’s preferred supplier agreement with Wärtsilä Gas Power Systems (GPS).
A Binghamton University scientist and his international colleagues report on the successful synthesis of the first superconductor designed entirely on the computer. Their findings were published in Physical Review Letters.
On October 8 François Englert of Belgium and Peter Higgs of Britain were awarded the 2013 Nobel Prize in physics for their theoretical discoveries on how subatomic particles acquire mass.
The Compact Linear Collider (CLIC) is a study for a future accelerator that will reach unprecedented energies for electrons and their antimatter twins, positrons.
Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...
Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...
The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

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...
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...
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...
I am in search of information regarding cryogenic thermophysical property data, specifically, Thermal Conductivity, Thermal Expansion, Stiffness and Modulus, in the 20K range. My list of materials include: Ti-6AL-4V (ELI), Al 6061-T651, and Invar (36%, plus any other composition which might have data available). Other materials which would be helpful...
I am with the Goodrich Corporation, an Aerospace products manufacturer. We currently utilize a number of environmental chambers (LN2 based) for environmental type conformity testing.
