Scaling Up Cryogenics for Quantum Computing

As we enter 2024, the field of quantum computing continues to develop rapidly. Accessibility to quantum processing and the scaling of systems are key factors in the growing industry. Cloud-based services offer one potential access route to quantum processing, but systems are also being deployed for customers to host on-premises....

‘First-Ever’ Cryogenic Refueling space Mission Announced

Two space infrastructure specialists, Space Machines Company and Spaceium, have joined forces to embark on what they believe to be the first-ever cryogenic refueling space mission in space in 2025. Under terms of a signed agreement, Canada’s Spaceium will integrate its cryogenic storage technology into Space Machine’s platform. Spaceium will then...

Cryogenics Airmen Supply Cool Fuel for Climatic Munition Test

During the intense heat of summer and throughout the humid Florida fall, Airmen donned protective gear to handle, manage, and deliver over 19,000 gallons of liquid nitrogen at temperatures below minus 300 degrees Fahrenheit to support a three-month munition test at Eglin Air Force Base. The 96th Logistics Readiness Squadron’s...

NASA’s Cryo Efforts Beyond the Atmosphere

Establishing sustained operations on the moon and Mars presents a multitude of opportunities and challenges NASA has yet to encounter. Many of these activities require new technologies and processes to ensure the agency is prepared for its ambitious Artemis missions and those beyond. One of those challenges is working with cryogenic...

Indirect Cryogenic Grinding Enhances Steel Alloy Properties

The machining process covers many material removal procedures; among them, grinding is one of the most important. Improved grinding is crucial to improve the overall machining process; hence, many researches focused on enhancing the performance of grinding operations by focusing on factors like wear, chattering vibrations, grinding wheel topography, temperature,...

GenH2 Supplies Cryostat CS500 System to University

GenH2 has signed an agreement with the University of Melbourne to provide the Cryostat CS500 simulation platform for cryogenic and hydrogen R&D projects. GenH2’s Cryostat CS500 system is capable of testing a wide range of thermal insulation systems, materials, composites, or panels under both cryogenic-vacuum conditions and real-world conditions. The University...

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...
