ORNL Team Recognized as Highly Cited Researchers

Fifteen scientists at the Oak Ridge National Laboratory (CSA CSM) have been named 2018 Highly Cited Researchers. The list recognizes scientists for exceptional performance, demonstrated by the production of multiple highly cited papers that rank in the top one percent by citations.

LHC Ends Second Season, Prepares for New Achievements

Expert team members from CERN turned off the Large Hadron Collider in early December, ending the successful second run of the world’s most powerful particle accelerator. The complex will be shut down for about two years, according to CERN, enabling both major upgrades and renovation work.

MIT Discovers Material that Performs as Both Topological Insulator and Superconductor

The Massachusetts Institute of Technology reports that the exact same material can be turned into either a topological insulator or a superconductor. The new findings reveal that in a single-layer crystal form, at temperatures from less than 1 K to the liquid nitrogen range of -320°F, hosts three distinct phases,...

Cool Innovations for Clean Energy

Cryogenic technology is making it possible for liquid air, nitrogen and methane—including methane derived from cow slurry—to play roles in combating global warming. Read more about these efforts in coverage from physicsworld.

Why Physics Needs a Post-LHC Collider

The Large Hadron Collider is the most powerful particle accelerator ever built, and scientists there have pushed the frontiers of particle physics past old boundaries, achieving higher energies and greater numbers of collisions than ever before. So far all the colliders up through the LHC have revealed particles that behave...

Pushing the Extra Cold Frontiers of Superconducting Science

Measuring the properties of superconducting materials in magnetic fields at temperatures close to absolute zero is considered difficult but necessary by many researchers, helping them understand quantum properties.

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...

Looking for process to freeze large volumes of plastics and rubber

I’m looking for a process to freeze large volumes of plastics and rubber prior to submitting this mass of material to a grinding process that reduces it to a powder. Any thoughts? Any known processes which I can visit? Any known technologies? Can you refer me to other resources for...

Sealant Adhesive KAE 89?

Can you give me contact details for the manufacturer of a “sealant Adhesive” KAE 89? It is a vapor stop, used on insulation covering LNG carrying conduits. This is a suggested alternative to Foster 90-66. Do you have details of any other alternative products for this application?

Data for thermal conductivity for phenoloc high pressure laminate NEMA CE grade

Can you provide data or information on how to obtain data for thermal conductivity for phenolic high pressure laminate NEMA CE grade, at low temperatures (4 Kelvin to 100 Kelvin)?

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.
