CRESST uncovers hint of dark matter
Physicists are finally closing in on dark matter, the elusive substance thought to make up most of the matter in the universe. Either that, or they’re being misled by some unknown source of error.
New superconductor fibers carry 40 times more electricity
Wiring systems powered by highly efficient superconductors have long been a dream of science, but researchers have faced such practical challenges as finding pliable and cost-effective materials. Now researchers at Tel Aviv University (TAU) have found a way to make an old idea new with the next generation of superconductors.

Helium-3
Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...
Cryopumping
Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...
Thermal Acoustic Oscillations
Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...
Air Separation and Liquefaction

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...
Rotating shaft seal for liquid to gaseous hydrogen?
I am constructing a cryogenic generator for the Air Force. It operates at 15,000 rpm for Liquid Hydrogen. I need a rotating shaft seal that will work with liquid to gaseous hydrogen. Where can I source seals for this application?
Source to help with cryo-treating a Nickel-Aluminum-Bronze impeller?
I am a graduate student at Penn State University working on a cavitation resistance project via cryo-treating a Nickel-Aluminum-Bronze impeller.
Looking for technical papers on the effect of processing metals at liquid helium temperatures.
I am a metallurgical engineer looking for technical papers on the effect of processing metals at liquid helium temperatures. In anyone familiar with any work in this field?
Quantitative data on mechanical properties for AISI 4340 alloy steel
I have a potential client who is looking for quantitative data on mechanical properties, particularly fatigue properties, with and without cryogenic tempering at -300/-320 degrees F for AISI 4340 alloy steel. Can you point me in the right direction?
