Balancing the Cryopreservation Equation
BioCision executives Dr. Maria Thompson, Dr. Eric Kunkel and Dr. Rolf Ehrhardt discuss the thawing arm of the "cryopreservation equation" and the need to strictly control temperature throughout the process.

SuperPower expands Quick Ship inventory
New segments have been added to SuperPower's Quick Ship inventory. The program enables the company to ship wire to clients in as little as 1-2 business days upon acceptance of a purchase order or pre-payment.
Neutrinos can deliver both full-on hits and “glancing blows”
In what they call a “weird little corner” of the already weird world of neutrinos, physicists have found evidence that neutrinos might be involved in a surprising reaction: interacting with a nucleus and leaving it basically untouched, inflicting no more than a glancing blow.
Accelerator-powered carbon dating
Accelerator mass spectrometry, an accelerator-driven form of carbon dating that requires only a tiny sample of the material, is advancing everything from archaeology to personalized medicine.
First LHC magnets prepped for restart
One-eighth of the Large Hadron Collider (LHC) dipole magnets have reached the energy they'll need to operate in 2015. Engineers at CERN powered 154 superconducting magnets to a current of around 11,000 amps. This is about 1,000 times greater than an average household appliance and is required to make the...
Save the Date for the 2015 Space Cryogenics Workshop
NASA Glenn Research Center announces the 2015 Space Cryogenics Workshop (SCW), a division of the Cryogenic Society of America. All aspects of space cryogenics will be represented, with an emphasis on work related to previous missions as well as future research.

Space Cryogenics
Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...
Exergy
The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...
Cryogenic Treatment
Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...
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...
Information on how the emissivity of the panel changes with air fouling?
I work at a facility with a large thermal vacuum chamber. We are using both nitrogen and helium shrouds.
In search of a calculation for designing a cryostat
I am a final year physics student at the University of Birmingham, and as part of a group I am currently designing a cryostat. One of the calculations I need to make (very soon!) is how much heat will be conducted down the walls. All information I have found so...
Safety of ethylene glycol and pressurized oxygen
We are reviewing the product design of liquid filled differential level gauges and want to insure that they meet the industry requirements. The former license owner had authorized that a fill fluid of ethylene glycol (68%) and distilled water (32%) could be used for oxygen service up to 500 psi....
Heat flux in case of vacuum loss on cryogenic surfaces?
Is there anyone who has information about the heat flux in case of vacuum loss on cryogenic surfaces?
