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...

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

Air Separation and Liquefaction

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...

Approximating pressure changes over time in cryogenic cylinders

I am an Air Resources Engineer with the California Air Resources Board (CARB). My senior management has asked me to investigate approximating pressure changes over time in cryogenic cylinders that contain LNG. So far, I have taken a stab at the problem, seeking to take a back-of-the-envelope approach (as directed...
