CERN Showcases Projects With Environmental Applications

CERN researchers are contributing to a growing number of projects aimed at developing technological solutions to environmental challenges—from fusion power and marine pollution detection to renewable energy distribution and cleaner aviation. These initiatives, carried out with academic and industrial partners, are coordinated through the CERN Innovation Programme for Environmental Applications...

New Evidence Sheds Light on Mystery of Magic-Angle Graphene’s Superconductivity

By Victoria Corless Scientists studying “magic-angle” graphene have captured the clearest evidence yet of the electronic signature behind its superconductivity, cutting through years of speculation about what drives its exotic behavior. “When superconductivity was first discovered in magic-angle graphene, it was surprising,” says Jeong Min Park of Princeton University. “Graphene...

New Near-Zero-Temperature Atomic Clock Aims to Redefine How Precisely We Measure Time

ByNeetika Walter Scientists in Toronto have unveiled a chilling breakthrough: a laser-regulated atomic clock cooled to just five degrees above absolute zero, promising a leap in timekeeping accuracy unlike anything used today. Physicists at the University of Toronto have developed the world’s first cryogenic single-ion optical atomic clock, a next-generation...

attocube and Quandela Deliver Lucy: World’s Most AdvancedPhotonic Quantum Computer

The French-German consortium Quandela and attocube systems GmbH has successfully delivered Lucy, a 12-qubit photonic quantum computer, to the Très Grand Centre de Calcul (TGCC) at CEA in France. Procured by the EuroHPC Joint Undertaking under the EuroQCS-France initiative, Lucy marks a major milestone in Europe’s quantum computing roadmap. Lucy...

Cracking the Code to Human Organ Banking

by Dr. Lakshya Gangwar, University of Minnesota Imagine a future where organs can be stored indefinitely “as glass,” and ready to be brought back to life at a moment’s notice. That’s the bold horizon sketched by a new study from University of Minnesota researchers, published in Nature Communications, 16 8511...

Stirling’s Liquid Nitrogen Solution for Smallholder Farmers Displays the Power of Cold

by Pranav Date, Stirling Cryogenics The Cold Chain Problem in Africa Africa’s agricultural productivity has been steadily improving, yet the absence of cold storage facilities in rural regions continues to pose severe challenges. Without reliable refrigeration, perishable goods often spoil before they can reach markets. This results in high post-harvest...

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

Air Separation and Liquefaction

by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. 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...

What is the temperature range of cryogenics?

Could you please tell me what is the temperature range of cryogenics? In other words, is -100°F considered cryogenic, or does it start lower? Could I expect to see some extended life in D2 stamping dies? What would the recipe be to achieve the desired results using cryogenics?
