Information about cryogenic cutting systems?
Can you refer me to someone with information about cryogenic cutting systems? I have read some information that was developed using liquid nitrogen and solidified carbon dioxide pellets to cut much like an abrasive water jet. Is this technology still available, and do you have any sources to contact?
Cryogenic process to separate high purity CO from mixture
I am looking for a cryogenic process to separate high purity CO (Carbon Monoxide) from a mixture of CO, CO2 and H2, plus small amounts of CH4.
Cryo tempering business advice
My friend has a racing engine company in NC. He suggested I start a cryo tempering business there because of all the race shops around that source it out. Can you tell me or put me in touch with someone who can tell me what “turn key” would be required...
Open cycle coolers with capacity of 1,500 Q @ 100K?
Does anyone know of any open cycle coolers with a capacity of 1,500 Q @ 100K in the country, preferably as an off-the-shelf product?

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...
Looking for the thermal conductivity of the high density polyethylene (HDPE) between 1.9 and 10K
I am looking for the thermal conductivity of the high density polyethylene (HDPE) between 1.9 and 10K (or even up to higher temperatures). The best would be to have these data for the HDPE material which sold by the CERN shop, which has a density of 0.95 g/cm3. Pier Paolo...
What is "Alpha" cryogenic processing?
Can somebody please tell me what the “Alpha Cryogenic Process” is? How is it different from ordinary cryogenic processing? Bernd Ahne, HiFi-Tuning
Do Stirling coolers have any relation to Stirling engines?
I was just wondering, do Stirling coolers have any relation to Stirling engines?
What type of MLI should be used in LOX (VJ) lines and flex hoses?
I work for ASRC Aerospace at the Kennedy Space Center (KSC). We support NASA in ground support equipment (GSE) design. I have a question concerning the type of multilayer insulation (MLI) to use in LOX vacuum Jacketed (VJ) lines and flex hoses.
