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.

Transfer Lines
Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...
Zero Boiloff
Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...
Cryomodule
Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...
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...
Data on thermal expansion down to 40K
For our cold mechanics, we use ball bearings from ADR from stainless steel which is AISI 440C, DIN X105CrMo17, W.Nr. 1.4125. Does anyone know the data of thermal expansion of this material down to 40 K?
Difference between radar and servo gauge for LNG tanks?
What is the difference between radar and servo gauge for LNG tanks? How do I understand the gauging system for LNG tanks and choose the best one?
Materials for "cryogenics in spacetech"?
I had to take a seminar in a national competition that is to be held in our country on the topic “cryogenics in spacetech.” For this, I need some materials related to it, and I thought to approach you for help. Can you suggest some relevant materials?
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.
