Physicists Uncover New Mechanism Enabling Magnetism, Superconductivity to Coexist in the Same Material

Physicists at the University of Bath, in collaboration with researchers from the US, have uncovered a new mechanism for enabling magnetism and superconductivity to co-exist in the same material. Until now, scientists could only guess how this unusual coexistence might be possible. The discovery could lead to applications in green...

Monolayer Superconductor Exhibits Unusual Behavior

Cornell researchers have discovered a rare “pseudogap” phenomenon that helps explain how the superconducting transition temperature can be greatly boosted in a single monolayer of iron selenide, and how it might be applied to other superconducting materials.

Airbus Establishes Zero-Emission Development Centers in Germany and France

Airbus has decided to concentrate its efforts for metallic hydrogen tanks in a complementary setup by creating Zero-Emission Development Centers (ZEDC) at its sites in Bremen (Germany) and in Nantes (France). The goal of the ZEDC is to achieve cost-competitive cryogenic tank manufacturing to support the successful future market launch...

Relativity Space Raises $650M to Scale Terran R Production

Relativity Space, the first company to 3D print an entire rocket and build the largest metal 3D printers in the world, announced it closed a $650 million Series E equity funding round. The round was led by Fidelity Management & Research Company LLC with participation from investors including Baillie Gifford,...

North American Helium Provides Corporate, Operational Update

North American Helium Inc. provides a corporate and operational update on recent substantial achievements by the company in Battle Creek. Commenting on today’s announcement, Mr. Nicholas Snyder, chairman and chief executive officer stated, “Bringing a facility like this online ahead of schedule and under budget despite numerous challenges from the...

Inside Microsoft’s Quantum Labs in Sydney

As their nuclear warheads decay, the US military captures the helium-3 and supplies it to physicists like Professor David Reilly who, with his team comprising some of the sharpest minds in the world, uses it to cool down the dilution fridges that help chip away at what could be the...

Latest in Defining Cryogenics

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

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...
