DOE study: LNG exports to benefit American economy

The US Department of Energy (DOE) has released its study on the economic impacts of liquefied natural gas (LNG) exports. DOE’s analysis finds that the US economy will experience “net economic benefits” from allowing increased LNG exports. It found that the natural gas boom has helped create jobs and spur...

Science and engineering students petition Congress: Stop sequestration

Science and engineering students have hand-delivered a petition to the local offices of all US senators and House leaders, requesting that sequestration be halted because it would harm their future as innovators and hurt economic growth in the United States. The students represent numerous scientific societies across the United States,...

Lake Shore issues new model CRX-VF probe station specifications

Lake Shore Cryotronics, a CSA Corporate Sustaining Member, has introduced updated specifications for its Model CRX-VF cryogenic probe station, which features increased maximum magnetic field, improved magnetic field at elevated sample temperatures and improved vacuum performance.

Scientists discover new phi-Josephson junction for use in cryoelectronics

Scientists from the University of Tübingen, Germany, working with colleagues from Tel Aviv University and the University of Kiel, Germany, have proposed [1] and experimentally demonstrated [2] a new type of superconducting element – named the phi-Josephson (?-Josephson) junction. Implemented in cryogenic devices, this element will make superconducting electronic circuits...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of  the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

Air Separation and Liquefaction

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...
