Cryogenics in Motion: Spaceline Delivers Advanced Nitrogen Trailer for NASA Armstrong

Spaceline Technologies, a fluid system engineering and manufacturing company, has completed a cryogenic nitrogen transport and supply trailer for NASA Armstrong Flight Research Center. This trailer is a mobile and standalone solution to provide pressure regulated nitrogen gas and liquid with flowrate and temperature control. Control of the trailer can...

Cryogenics and the Road to Superconducting Propulsion: Part I for Aircrafts

by Quan-Sheng Shu, cryospc.com and Jonathan Demko, Le Tourneau University Superconducting (SC) motors are pivotal for future transportation, offering power densities exceeding 20 kW/kg. Cooling philosophies diverge by architecture: partially superconducting aircraft designs (like NASA’s HEMM) utilize integrated mechanical cryocoolers for the rotor, whereas fully superconducting aircraft favor liquid hydrogen...

Pelican Wire Designs for Cryogenic and Extreme Energy Systems

As renewable energy, electrification and advanced research technologies continue to expand, the demands placed on wire and cable systems are evolving just as rapidly. Higher power densities, tighter system integration and increasingly extreme operating environments are pushing manufacturers beyond traditional commodity wire solutions. Caleb Lemmons, Business Development Manager at Pelican...

Meet the 2026 Young Professionals

This feature introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields. Debuted in the 2006 issue, the feature has presented many young persons whom we are proud to see have...

Extraterrestrial Specifications for Cryogenic Fluid Production

by Wesley Johnson, NASA Glenn Research Center Here on our home planet, where we have been liquefying various “permanent gasses” since 1877 [1], most of us take it for granted that when we go out to buy a cryogenic liquid (or even a pure gas) we don’t have to write...

Cold Power: How Cryogenics Will Make Chicago the Taiwan of Quantum Computing

by Joe Procunier, LJC Design & Engineering Chicago is set to redefine the future of quantum computing, just as Taiwan reshaped the global semiconductor industry. In 1987, Morris Chang famously started TSMC (Taiwan Semiconductor Manufacturing Company) after working as a pivotal figure at Texas Instruments.[1] The Taiwanese government encouraged him...

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...

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...
