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.

Successful Trial Operation of World’s First Hydrogen-Powered Trains Completed

Alstom S.A. of Saint-Ouen, France, has announced that after 530 days and more than 180,000 driven kilometers, the successful trial operation of the world’s first two hydrogen trains was officially completed at the end of February.

VTT to Build Finland’s First Quantum Computer, Seeks to Bolster Finland’s and Europe’s Quantum Competitiveness

VTT Technical Research Center in Espoo, Finland, has launched a project to acquire Finland’s first quantum computer. The first phase of this three-phase project seeks to bolster Finland’s ability to design and build quantum computers and to create a competence base for future applications. The design and construction of the...

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...

Scientists Use Light to Accelerate Supercurrents, Access ‘Forbidden’ Light, Quantum Properties

Scientists at Iowa State University are using light waves to accelerate supercurrents and access the unique properties of the quantum world, including "forbidden" light emissions that one day could be applied to high speed quantum computers, communications and other technologies. The scientists have seen unexpected things in supercurrents—electricity that moves...

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...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...
