In an email to its members, the Compressed Gas Association announced the formation of a new Process Safety Committee to address process safety concerns and gaps that affect the industrial gas industry.
Auguste Cryogenics SK s.r.o. has acquired Taylor-Wharton International’s European Operations, including a cryogenic pressure vessel manufacturing facility, Taylor-Wharton Slovakia s.r.o., and the related warehouse and office complex of Taylor-Wharton Germany GmbH. Auguste says all employees have been retained and that the facilities will continue to operate under the Taylor-Wharton brand...
Engineers at European XFEL, a large international research facility with 11 European member countries, have begun commissioning a 3.4-km-long underground X-ray laser. When operational, the laser will generate extremely short and bright X-ray light flashes that will enable new views of the structure and fast processes of the nanocosmos. Applications...
The Royal Swedish Academy of Sciences awarded the 2016 Nobel Prize in Physics to David J. Thouless, F. Duncan M. Haldane and J. Michael Kosterlitz, three laureates who have used advanced topological methods to study unusual phases of matter, such as superconductors, superfluids or thin magnetic films. Thanks to their...
Oak Ridge National Laboratory (CSA CSM) celebrated a decade of research at its Spallation Neutron Source (SNS) with an event on September 22. The SNS features a linear accelerator and accumulator ring. It sent the first protons to its one-of-a-kind mercury target in April 2006 and over the last decade...
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...
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...
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...

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...
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...
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...
Greetings from Australia. I am looking for a company that I might contact that has any experience or has done any research into cryogenic processing for medical equipment, in particular, joint prosthesis.
