Hypres delivers Digital-RF (TM) receiver systems to ONR
Hypres Inc. has delivered two Digital-RF (TM) receiver systems to the U.S. Department of Defense's Office of Naval Research. The systems will serve as test beds to evaluate Digital-RF technology for wireless communications applications.
Zenergy announces extension of Rheinbach, Germany facility
Zenergy Power plc announced that it will expand its manufacturing facility based in Rheinbach, Germany, allowing the company to accommodate the expected increase in production of its ground-breaking HTS induction heater.
Synchronization of LHC beam transfer system a success
According to R&D Magazine, synchronization of the Large Hadron Collider's beam transfer system was shown to be successful through tests that began on August 8th. These preliminary tests are in preparation for the LHC's official first run on September 10, 2008, which will be webcast at webcast.cern.ch.

Adiabatic Demagnetization Refrigeration
Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...
Cryogen-Free
A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...
Cryostats and Cryocoolers
A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...
Air Separation and Liquefaction

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.
