A team from Ames Laboratory and the University of Alabama Birmingham has discovered a remarkable new state of matter within an iron pnictide superconductor, revealing a laser-induced formation of collective behaviors that compete with superconductivity around 16 K.
SpaceX indicates that a test vehicle for the company’s next-generation launch system could be ready for testing early in 2019. The test hopper will be powered by three of the company’s methane/liquid oxygen engines, units that were "radically redesigned" according to chief executive Elon Musk.
A US military base in Okinawa includes the only cryogenic facility for the US Air Force in Japan, producing and supplying the oxygen and nitrogen necessary to keep US aircraft in the sky. The unit, however, is also known for saving local lives and making ice cream.
Symmetry writer Mike Perricone presented readers with his annual compilation of popular science books related to particle physics and astrophysics. The list includes more than ten suggestions, including "Particle Physics Brick by Brick: Atomic and Subatomic Physics Explained...in LEGO," by Dr. Ben Still.
The Linde Group (CSA CSM) has opened another hydrogen station in Hanover, Germany. The company is using the next generation of its proprietary cryogenic pump, converting stored liquid hydrogen into a gaseous state compressed to 900 bar. There are currently 55 hydrogen filling stations in Germany, and 100 stations scheduled...
Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...
The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...
Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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 remembering in the 1970’s when astronauts were walking on the moon and carried oxygen in 300 ss bottles inside LN2 tanks which were filled and pressurized.
I am an engineer looking to improve our solenoid valve sealing on cryogenic medias. I was wondering if you knew of materials other then PTFE or glass filled PTFE that could be used for sealing.
