NAWCAD Lakehurst enhances Cryogenic Systems for Naval Aviation

As the Cryogenics and Corrosion Control Support Equipment (SE) Integrated Product Team (IPT) Lead at NAWCAD Lakehurst, Asif Yeahia knows that many people may not fully understand the work his team does. However, working with substances at temperatures below negative 200 degrees gives them one of the “coolest” jobs at the...

Room-Size Particle Accelerators Go Commercial

By Charles Q. Choi Particle accelerators are usually huge structures—think of the 3.2-kilometer–long SLAC National Accelerator Laboratory in Stanford, Calif. But scientists have been hard at work trying to shrink these accelerators down by using lasers to perform the accelerating. These particle accelerators would be the size of single room, and cost much less as well. Now, a startup says...

Chinese Physicists Settle Einstein and Bohr’s Quantum Debate

A groundbreaking experiment recreates Einstein’s 1927 thought challenge, confirming fundamental quantum principle. In a landmark study that brings a definitive close to one of the most famous debates in modern physics, a team of Chinese scientists has experimentally validated Niels Bohr’s core quantum principle, demonstrating that a particle’s path and...

Twisted Stacks of 2-D Carbon Act Like a Weird Type of Superconductor

“Magic-angle” graphene could help solve the puzzle of how unconventional superconductors work By Emily Conover Stacks of graphene, carefully twisted, gain a superpower: They become superconductors. Now scientists have new evidence that this “magic-angle” graphene is a member of a truly strange class of superconductor. Like all superconductors, the materials, known...

World-First High-Current Terminals for Liquid Hydrogen

Kyocera Corporation (President and CEO: Hideo Tanimoto, hereinafter referred to as “Kyocera”) is pleased to announce that, through joint research with the Japan Aerospace Exploration Agency (hereinafter referred to as “JAXA”), it has developed two new products: a 100A current feedthrough terminal that ensures durability and airtightness in liquid hydrogen...

Making a Splash on Cryogenic Surfaces

Cryogenic surfaces do not hinder droplet splashing, but smaller droplets make smaller splashes. Hannah Richter On a rainy day, a classic physical property is on display: droplet splashing. How liquids splash is not just important for keeping one’s clothes dry, but for applications from inkjet printing to spraying crops to...

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...

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?
