Daimler Truck Testing Fuel-cell Truck with Liquid Hydrogen; sLH2 Refueling

Since last year, a Mercedes-Benz GenH2 Truck fuel-cell prototype has been undergoing intensive testing both on the in-house test track and on public roads. Daimler Truck is now putting another prototype into operation to test the use of liquid hydrogen. Political support for the development program comes from Daniela Schmitt, Minister of Economic...

FormFactor Launches Cryogenic Test Service to Dramatically Reduce the Time and Cost for Superconducting Qubit Characterization

FormFactor, Inc., a leading semiconductor test and measurement supplier, today announced an innovative and new cryogenic test service business model designed to accelerate quantum computing IC development and characterization. Quantum developers can now leverage FormFactor’s state-of-the-art Advanced Cryogenic Lab located at Boulder, Colorado, to characterize qubits and resonators using cryostats...

Launch Vehicle Propelled by Innovative Heat Exchanger

Writing in the journal Cryogenics, a team of scientists from the Korea Aerospace Research Institute has evaluated the performance of a helium heat exchanger for launch vehicles. Performance was evaluated under real engine operating conditions.  Launch Vehicles Efficient launch vehicle design is vital for the spacetech industry. Technology has advanced since the...

With Helium in Short Supply, Scientists Are Worried

In the basement of the University of New Mexico’s chemistry building, Karen Smith punched in the code to get into the lab she manages. Inside, three white cylinders on blue legs that looked sort of like nine-foot-tall cousins of R2-D2 were humming away. “You’re going to want to stay fairly close...

Cryogenic Pumps for Research

Vanzetti Engineering’s cryogenic pumps have been chosen for the Aria Project of the National Institute of Nuclear Physics (INFN) in partnership with Carbosulcis S.p.A., a company owned by the Sardinia Region. The Aria Project involves the construction of a cryogenic distillation tower in Sardinia, Italy, for the production of high purity...

Air Liquide Inaugurates Liquid Hydrogen Plant in Nevada

Oxygen, nitrogen and hydrogen are essential small molecules for life, matter and energy. They embody Air Liquide’s scientific territory and have been at the core of the company’s activities since its creation in 1902. A world leader in gases, technologies and services for industry and health, Air Liquide’s ambition is...

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...

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...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Assistance with resolving a sealing problem?

We are fabricating piping components for refrigeration service. These components must be leak checked at 15 bar (218 psig). We are using a gas test media that is 25% helium and experiencing difficulty on maintaining a seal on the flanged connections. Do you know anyone or any references that could...

Cryogenic data on leather and nomex

Could anyone please help me out with the following cryogenics data: Leather — mechanical properties at 77 K or lower Nomex — thermal conductivity @ 4 to 50 K I lost the data I had some time ago and although this should be easily accessible, I can’t find any reference...
