Mactac Unveils New Cryogenic Labels

Mactac, a North American adhesives, label and packaging company, has launched new cryogenic labelstocks for temperatures as low as -320º F. Mactac’s cryogenic labelstocks are intended for harsh environment applications where labels must withstand exposure to liquid nitrogen or ultralow temperature freezers, thaw cycles, chemicals and solvents.

Coregas Supporting Coal-to-Hydrogen Project in Australia

A world-first project in Victoria, Australia, that will convert brown coal to hydrogen for export to Japan is being supported by the only Australian-owned industrial gas company, Coregas. The Hydrogen Energy Supply Chain (HESC) project will see liquefied hydrogen produced from Latrobe Valley brown coal transported to Japan for use...

They Are There and They Are Gone: ICARUS Chases a Fourth Neutrino

On February 21, scientists at Fermi National Accelerator Laboratory (Fermilab) (CSA CSM) began cooling down ICARUS—the largest particle detector in the lab’s Short-Baseline Neutrino Program—and filling it with 760 tons of liquid argon. This moves ICARUS closer to operation and the search for a fourth type of neutrino. “The Short-Baseline...

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...
