Shell and its affiliates have signed a memorandum of understanding with TravelCenters of America LLC (TA) to sell liquefied natural gas (LNG) to heavy-duty road transport customers in the US through TA’s existing nationwide network of full-service fueling centers.
DOE's Jefferson Lab is in the midst of a $310 million upgrade project to provide physicists worldwide with an unprecedented ability to study the basic building blocks of matter. Now, key components of the upgrade to the lab’s particle accelerator have aced a rigorous test conducted under real operating conditions,...
Superconductivity, in which electric current flows without resistance, promises huge energy savings – from low-voltage electric grids with no transmission losses, superefficient motors and generators and myriad other schemes.
NASA is seeking proposals from accredited US universities focused on innovative, early-stage space technologies that will improve shielding from space radiation, spacecraft thermal management and optical systems.
Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...
While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...
The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
I am in search of information regarding cryogenic thermophysical property data, specifically, Thermal Conductivity, Thermal Expansion, Stiffness and Modulus, in the 20K range. My list of materials include: Ti-6AL-4V (ELI), Al 6061-T651, and Invar (36%, plus any other composition which might have data available). Other materials which would be helpful...
I am with the Goodrich Corporation, an Aerospace products manufacturer. We currently utilize a number of environmental chambers (LN2 based) for environmental type conformity testing.
For a technical presentation I would like to have some recommendations for low temperature applications of titanium and titanium alloys. Do you think you can help me?
