NIF Journeys to Ignition

December 5, 2022, marked a historic breakthrough in the field of fusion research as scientists achieved ignition, a momentous achievement that has been a scientific grand challenge spanning over 50 years. The National Ignition Facility (NIF) within the Lawrence Livermore National Laboratory (LLNL) achieved an igniting fusion reaction where the...

Partnership Revolutionizes Healthcare with the MAGNETOM Terra 7 Tesla MRI Scanner

The University of Illinois Urbana-Champaign (UIUC) and Carle Health, a vertically integrated healthcare system with hospitals, physician practices and a medical school, have formed a unique partnership to co-own and operate a Siemens Healthineers MAGNETOM Terra 7 Tesla MRI scanner. This collaboration has significant implications for both research and clinical...

Cryogenic Prober Determines Quality of Qubit Devices

Germany’s first cryogenic measuring setup for the statistical quality measurement of qubit devices on 200- and 300-mm wafers has commenced operation at Fraunhofer IAF. With the newly established cryogenic on-wafer prober, researchers at the Fraunhofer Institute for Applied Solid State Physics IAF aim to gain a deeper understanding of the...

Adult Corals Have Been Safely Frozen and Revived for the First Time

Like something out of science fiction, small colonies of mature corals have been safely frozen and revived for the first time, though more work will be needed to ensure their long-term survival, researchers report reported in Nature Communications. Freezing chunks of living corals for safekeeping — or cryopreserving them —...

GKN, Marshall and Parker to Cooperate on Hydrogen Flight

Aerospace industry supplier GKN Aerospace is joining forces with Marshall and Parker Aerospace to explore liquid hydrogen fuel systems for aircraft. The partners plan to develop a liquid hydrogen system suitable for both fuel cell and internal combustion engine aircraft. The planned collaboration will benefit from the UK government-funded H2GEAR...

Unveiling the Intricate Protein Complex Guiding Signaling to Cilia

Cilia, the tiny hair-like projections found on the surface of most eukaryotic cells, act as the conduits for a myriad of signaling processes that orchestrate cellular activities. However, these intricate organelles are not equipped to craft the signaling proteins themselves. Instead, they rely on an intricate network of transport mechanisms...

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...
