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...

Nitrofreeze Cryogenic Solutions Dry Ice Blasts for Historic Restorations

By Ryan Taylor, Nitrofreeze Cryogenic Solutions Dry ice blasting is used in a wide range of historic restoration projects, including a recent one completed in Rockport, Mass., in July of this year. Nitrofreeze Cryogenic Solutions was contracted to dry ice blast barn board wood inside a fishing hut to lighten...

Zero-Loss Liquid Hydrogen Storage and Transfer Technology Transforms the Hydrogen Economy

By Greg Gosnell, CEO of GenH2 Corp. Hydrogen is essential to reducing carbon emissions and transitioning away from fossil fuels. Yet storage and transfer losses of up to 40% have limited its cost-effectiveness and slowed adoption. The key to unlocking hydrogen’s potential lies in Zero-Loss Controlled Storage Technology. By minimizing...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium?

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
