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...

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...
