GOW-MAC Instrument Company, introduces the process oriented Series AR710 and AR720 gas analyzers with High Frequency Argon Discharge Ionization Detector (HFADD).
At the CEC/ICMC Awards Breakfast on July 2, Ray Radebaugh received the prestigious Samuel C. Collins Award for “an individual who has made outstanding contributions to the identification and solution of cryogenic engineering problems and has…demonstrated a concern for the cryogenic community through unselfish professional service and leadership to this...
Immunovative Therapies, Ltd. recently announced that its New Drug (IND) application was cleared by the US Food and Drug Administration, allowing the company to begin clinical trials of its experimental CryoStim™ cancer vaccine product for the treatment of advanced metastatic solid tumors.
The 2009 Cryogenic Engineering Conference/International Cryogenic Materials Conference brought together almost 500 persons from all areas of cryogenics to exchange technology and ideas.
Two-phase flows are those flows in which there is a mixture of two physical states (solid, liquid or vapor). In cryogenic applications, such flows are almost always a mixture of a cryogenic liquid along with its corresponding vapor. A mixture of liquid helium and helium vapor would be a typical...
A supercritical fluid is defined as a substance whose temperature and pressure exceed those of its critical point. Every pure substance has a critical point that is defined in thermodynamic space by a critical temperature and a corresponding critical pressure. For example, the critical point for helium has a critical...
The Brayton cycle is one of the many thermodynamic cycles used to generate cooling at cryogenic temperatures. Strictly speaking, when referring to cooling we should call this the reverse Brayton cycle as the original Brayton cycle describes the process of power generation or propulsion via a gas turbine. In many...

You are encouraged to read Cryo Central’s History...
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...
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.
I am a final year Physics Undergraduate at the University of Cambridge (UK). As a part of one of my courses this year, I have been asked to investigate the use of hydrophobic surfaces in cryogenics.
