Helium II
Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...
Manufacturers of cryogenic regenerator lead spheres?
Would you please suggest a few manufacturers that produce cryogenic regenerator lead spheres? The size we need is 0.15mm-0.2mm. I don’t have a lot of ideas for where to go to purchase them.
Assistance with resolving a sealing problem?
We are fabricating piping components for refrigeration service. These components must be leak checked at 15 bar (218 psig). We are using a gas test media that is 25% helium and experiencing difficulty on maintaining a seal on the flanged connections. Do you know anyone or any references that could...
Cryogenic data on leather and nomex
Could anyone please help me out with the following cryogenics data: Leather — mechanical properties at 77 K or lower Nomex — thermal conductivity @ 4 to 50 K I lost the data I had some time ago and although this should be easily accessible, I can’t find any reference...
