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...

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...

Air Products to Build Europe’s Largest Blue Hydrogen Plant

Air Products announced it will build, own and operate a state-of-the-art carbon capture and carbon dioxide (CO2) treatment facility at its existing hydrogen production plant in Rotterdam, the Netherlands. The facility is expected to be on-stream in 2026, and the resulting “blue” hydrogen product to serve ExxonMobil’s (Esso) Rotterdam refinery...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...

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...

Metallic Salts Normally Used to Produce Ultra-Low Temperatures?

Regarding the method known as the Adiabatic Demagnetization of Paramagnetic Salts: What metallic salts are normally used to produce the ultra-low temperatures used for near-absolute-zero cryogenic research? Which salts are the most efficient? Which make the best cooling agents? And which are used most commonly by physicists? I am looking...

Specs and info on turbo expanders

I am a fourth year chemical engineering student doing a design project for the liquefaction of natural gas to DME and we are using a turbo expansion unit. I was wondering whether you would send me some specs and any additional information on turbo expanders that I could use as...
