En Route Toward the First German Quantum Computer

Fraunhofer IPMS is collaborating on the development of an integrated German quantum computer based on superconducting quantum chips. Together with 24 German research institutions and companies, under the coordination of Forschungszentrum (FZ) Jülich, Fraunhofer IPMS is working on this quantum computer with the goal of improving error rates. At the halfway...

Indian Student to Research Liquid Hydrogen with Monash University

A Ph.D. student from India is conducting groundbreaking research with Monash University’s Department of Civil Engineering after being selected as the recipient of the prestigious Australian government-funded Maitri Scholars Program. Chennai native Rohith Prakash will focus on advancing the safe transport and storage of liquid hydrogen, with a particular emphasis on...

Lightweight Supramolecular Material for Compressed Hydrogen Storage

A team of chemists from the University of Hong Kong, Northwestern University, and Duke University has developed a supramolecular material capable of compressing hydrogen for storage without being too heavy. Their study, published in Nature Chemistry, demonstrates the use of porous organic crystals for hydrogen storage. Hydrogen has long been...

Rising Helium Demand Set to Double by 2035

A new report from IDTechEx suggests that global helium demand is set to double by 2035, driven by the wide-ranging applications of this vital element. Helium, a finite yet critical resource, is indispensable across multiple industries. From medical imaging to semiconductor manufacturing, helium’s unique properties—such as high thermal conductivity, chemical...

Cryogenic Therapy Puts the Freeze on Esophageal Cancer

Patients with esophageal tumors often experience malignant dysphagia, or difficulty swallowing due to an obstruction, complicating their treatment and preventing them from eating normally. The Advanced Center for Therapeutic Endoscopy at WVU Medicine J.W. Ruby Memorial Hospital is the first in West Virginia to offer an innovative solution to this...

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...

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? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

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...

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?
