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...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...
