KEK Director General assesses earthquake damage, tells repair plans
Atsuto Suzuki, Director General at KEK, the Japanese high energy accelerator research organization, reported on damage caused by the recent earthquake and recovery prospects in his “DG’s Corner” column: First of all, I would like to express my deepest appreciation for the messages of concern, sympathy and encouragement that we...
Superconductivity pioneer Paul Chu featured in exhibit
Superconductivity Pioneer Paul Chu was featured in an unusual exhibit in Texas. A white lab coat and a pair of worn sneakers are almost standard-issue items for a research facility, but they don't seem to rise to the rank of museum exhibit. Yet, that’s exactly where you can find one...
Paul Chu expected more progress by now
Superconductivity pioneer Dr. Paul Chu expected faster progress since his discoveries, he told Cold Facts Editor Theresa Boehl in a recent brief interview. Cold Facts: Did you have any idea of the potential impact of superconductivity when you were doing your groundbreaking research years ago? Chu: Yes, I think I...

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...
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

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.
