The Shipping Industry Looks for Green Fuels

Look at all the surrounding stuff. Unless you’re in the middle of the desert or somewhere else far from civilization, nearly everything you see traveled to you by sea. “Ships bring 80–90% of most everything you want or need, or the raw materials used for making those things,” says Natasha Brown,...

Breakthrough Quantum Hardware to be Made in USA

Maybell Quantum unveiled the Icebox, a cryogenic platform to power the next generation of quantum computers. Maybell’s condenses a room-sized cryogenic setup into a system slightly larger than a kitchen fridge, cooling quantum devices to just a few thousandths of a degree above absolute zero. Maybell’s Icebox solves several pressing challenges...

JILA Atomic Clocks Measure Einstein’s General Relativity at Millimeter Scale

Physicists from JILA (formerly known as the Joint Institute for Laboratory Astrophysics, a physical science research institute at the University of Colorado Boulder campus and jointly operated by the National Institute of Standards and Technology [NIST] and the University of Colorado Boulder) have measured Albert Einstein’s theory of general relativity...

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...

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...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Any experience with G-10 in an extremely cold environment?

I have a cryostat with closed cycle cryocooler attached. The case is aluminum with a G-10 spacer between the case and a stainless steel bellows that supports the cryocooler.

Cryogenic sealant for LNG fueled buses?

Where can I find a cryogenic sealant for my LNG fueled buses?

Material/gel/epoxy to transfer cold temperature of a cryo-box to a test article

I’m on the hunt for a material/gel/epoxy that will transfer the cold temperature of a cryo-box to a test article. The cryo-box is curved and the test article is at the same curvature. I’m looking for something to put between them to make the surface of the test article as...
