CLNG president responds to senator’s comments on LNG exports
In response to comments from U.S. Sen. Ron Wyden suggesting the United States needs a policy on energy exports and that a "timeout" should be declared on permits to export LNG to non-Free Trade Agreement countries, Center for Liquefied Natural Gas (CLNG) President Bill Cooper issued the following statement:
Linde introduces new N2 pressure booster
Gas-assist injection molders (GAIM) can improve efficiency and quality -- even on lightweight parts and difficult geometries -- with the help of a new liquid nitrogen (N2) pressure booster from Linde North America.
Argonne named a “Best Place” for postdocs to work
For postdoctoral scholars, or postdocs, Argonne National Laboratory is the 6th best place to work in the United States, according to The Scientist, a life sciences magazine.
At DOE, body blows to fusion, nuclear physics and particle physics
Overall, the 2013 budget numbers for the Department of Energy's (DOE's) Office of Science, the single largest funder of physical sciences research in the United States, look reasonably good. The office would see its budget climb by 2.4% to $4.992 billion. Three of the office's six major research programs, however,...
CERN experiment makes spectroscopic measurement of antihydrogen
In a paper published online on March 7 by the journal Nature, the ALPHA collaboration at CERN reports an important milestone on the way to measuring the properties of antimatter atoms.

Dewar
A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...
Stirling and Gifford-McMahon Cryocoolers
Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...
Liquefied Natural Gas (LNG)
A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...
History of Cryogenics
From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...
Cryobiology
Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...
Cryogenic Insulation
James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...
Cryogenic Treatment of Materials
F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...
Investigating use of hydrophobic surfaces in cryogenics
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.
Could an Amateur Construct a Liquid Air Plant?
I am a newly retired experimental physicist. Is it feasible for an “amateur” to construct a liquid air plant? Do you have detailed descriptions of older (presumably simpler) liquid air plants, or references that might be of assistance?
Data on the thermal contraction value for Aluminum 6061-T6?
I’m looking for data on the thermal contraction value for Aluminum 6061-T6. Can you guide me in the right direction?
Cryoforming of steel for pressure vessel applications?
Could you advise on me where to find some literature regarding the cryoforming of steel for pressure vessel applications?
