UK science budget safe – for now
The threat of budget cuts has created quite a buzz in the UK science community, but an announcement made yesterday assured scientists that funds will be frozen at £4.6 billion for the next four years.
“Mr. Freeze” brings cryogenics to home-schooled students
The Post-Tribune reported that Fermilab's "Mr. Freeze" gave a cryogenics demonstration to a group of home-schooled students at the South Lake Church of the Nazarene in Crown Point IN.
NIF completes first successful integrated experiment
The National Ignition Facility (NIF) recently completed its first integrated ignition experiment, which marks the beginning of its next phase on the way toward fusion ignition tests.

Refrigerators and Liquefiers
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
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...
Coefficient of Performance and Figure of Merit
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...

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...

I am looking for a company to design and manufacture a portable gas purity monitoring system using a cryostat/dewar/flow meter combination.
Consultant knowledgeable in LNG
My company is seeking a consultant who is knowledgeable in LNG. It is a project located overseas, and involves a refinery and heat exchangers. Can anyone provide me with a reference?
LN2 flow in cryotherapy device
I’m working on a cooler device that will be pretty similar to the devices commonly used in cryotherapy for cooling skin.
Source for small gas liquefier/cryocooler?
I would like to acquire a used gas liquefier/cryocooler for use in my non-profit project to build a high-performance natural gas (methane) powered car. I am interested in liquefying piped natural gas (methane) into LNG (about 120K or -154 degrees).
