Cold Atoms Act as Distant Messengers

Particles can interact directly by repelling or attracting each other, but how do particles interact when far apart? Scientists at the University of Chicago have discovered that atoms can actually exchange information using intermediary particles. Such research represents the first time this particular phenomenon has been observed in a cold...

Cryo-EM Helps Decipher 3D Structure for Cancer Treatment

A research team from Columbia University and Nimbus Therapeutics has successfully determined the 3D structure of human ATP-citrate lyase (ACLY), a metabolic enzyme that plays a key role in cancer cell proliferation and other cellular processes.

Cryogenic Technique Reveals Fraudulent Food and Drugs

Engineers from the University of California, Riverside have developed "chronoprinting," a new technique that can detect fake drugs and food using videos recorded while samples undergo alterations. The technology requires only a few relatively inexpensive pieces of equipment, free software to accurately distinguish pure from inferior food or medicine and...

NASA’s JPL Seeking Applicants for First Space Accelerator

NASA's first aerospace accelerator program will select 10 startup companies to take part in a three-month pilot program to develop new technologies for space. Applications will be accepted through April 7. Selected teams will develop concepts and business plans over a three-month period and then pitch their results to the...

TRIUMF Receives Historic Canadian Investment

The Government of Canada has announced a five year and $292.7M investment supporting laboratory operations at TRIUMF (CSA CSM). The donation comes in response to TRIUMF's recently published Five-Year Plan 2020-2025 and represents the country's largest single investment there to date.

Fermilab Breaks Ground on PIP-II

Fermi National Accelerator Laboratory (CSA CSM) has officially broken ground on a major new particle accelerator project that will power cutting-edge physics experiments for many decades to come. When complete, PIP-II will become the heart of the laboratory’s accelerator complex, vastly improving what is already the world’s most powerful particle...

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...

Definition or max temp which defines “cryogenic”?

Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
