Physicists, medical industry team up to build advanced cancer therapy accelerator
A new collaboration between the U.S. Department of Energy’s Brookhaven National Laboratory and Best Medical International (BMI) aims to design one of the most dynamic and effective cancer therapy devices in the world.
Fermilab’s SRF program incorporates old equipment into new designs
Some people make coffee coasters out of old newspapers or lawn ornaments out of rusty shovels. Fermilab is building a particle accelerator that employs $28 million of recycled equipment and material.
Academics rallying to boycott Elsevier
Over 4,000 scientists have signed an online petition in protest over the pricing and distribution policies of Elsevier, a publisher which sells over 2,000 academic journals along with 20,000 other books. Many of the signatories are distinguished academics at such institutions as Harvard, Yale, McGill, Cambridge and Oxford. They promise...
MSU Board approves next step of FRIB project
The Michigan State University Board of Trustees has given its approval to the next step in the development of the Facility for Rare Isotope Beams, a world-class nuclear research facility that will attract scientists from all over the world to East Lansing while creating more than $1 billion in economic...
Scientist recounts superconductivity discovery
Like many young men from Alabama, Jim Ashburn's path to fame involved football, good timing, a fair dose of serendipity (or good luck, if you prefer), timely coaching and a strong team. Ashburn's path also included a love of science, especially mathematics.

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...

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...
Eliminate negative effects of grinder burn on gear teeth?
Can you tell me if it is possible to eliminate the negative affects of grinder burn on gear teeth with the use of cryogenics?
Information about a process called “cryogenically stretch-formed ss”
I am remembering in the 1970’s when astronauts were walking on the moon and carried oxygen in 300 ss bottles inside LN2 tanks which were filled and pressurized.
Small cryo-gun for our health service clinic
I am Assistant Director for Environmental Health & Safety at a university health service clinic.
Additional sealing materials besides PTFE or glass filled PTFE
I am an engineer looking to improve our solenoid valve sealing on cryogenic medias. I was wondering if you knew of materials other then PTFE or glass filled PTFE that could be used for sealing.
