Six Things You Might Not Know About Hydrogen
October 8th is National Hydrogen and Fuel Cell Day. To celebrate, here are a few things you might not know about hydrogen and fuel cells.
Auguste Acquires Taylor-Wharton’s European Operations
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...
XFEL Commissions New X-ray Laser
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...
2016 Nobel Prize in Physics Awarded
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...
Spallation Neutron Source Marks a Decade of Research
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...

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...
Air Separation and Liquefaction
by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. 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...
Reliability and mounting of electronic substrates at low temperatures
I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...
Are 3D drawings included in the sale of a cryogenic plant?
I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...
Looking for a source of LOX impact testing to ASTM D2512
I have been looking for a source of LOX impact testing to ASTM D2512. I am aware of NASA and White Sands, but am looking for a commercial entity doing the work. No luck so far, even calling a lot of the folks on the CSA website. Any referrals will...
