NASA Explorers: Apollo Audio Series Celebrates the 50th Anniversary of Apollo 11

Listen to people from all over the world recount their favorite Apollo memories or share their hopes for what’s yet to come in space exploration. In a new audio series, listeners will hear from a moon detective, scientists who study space rocks and people from all over the world whose...

Research Group Sets New Temperature Record For Superconductivity

An international team of scientists has built a superconductor that functions at 250 K, nearly 50 °C (84.6 °F) hotter than the previous record high for superconductivity—and it puts the “holy grail” of energy transmission almost within reach. In a study published in Nature, scientists describe their new material, lanthanum...

The Language of Physics, According to Symmetry

Luminosity, quintessence, damping, oh my! Word fans rejoice, Symmetry has published another list of 10 common words that take on a new meaning when spoken by scientists.

Altus Midstream Announces First Cryogenic Processing Train in Service at Texas Complex

Altus Midstream introduced the first of its three new cryogenic processing trains at the Diamond Cryo Complex in Alpine High TX. It is now processing rich natural gas and delivering natural gas liquids (NGLs) and residue gas for sale.

Department of Energy Announces $75 Million for High-Energy Physics Research

The US Department of Energy recently announced grants of $75 million in funding for 66 university research awards. The projects involve scientists at 51 US institutions of higher learning and include both experimental and theoretical research into topics like the Higgs boson, neutrinos, dark matter, dark energy and the search...

Blue Origin Test-Fires Moon Lander Engines

Blue Origin recently fired up a brand-new engine, the BE-7, which the company developed for its future moon lander. Founder and CEO Jeff Bezos claims the lander, equipped with the BE-7, will be capable of carrying robotic rovers to the moon or even a separate spacecraft that can take off...

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...

Air Separation and Liquefaction

by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

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...

Cold Technology for Pest Control

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...

Cryogenic Finishing

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...

TS diagram for helium

Where can I obtain a really big, nice TS diagram for helium ?

Reliability and mounting of electronic substrates at low temperatures

I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...

Are 3D drawings included in the sale of a cryogenic plant?

I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...

Looking for a source of LOX impact testing to ASTM D2512

I have been looking for a source of LOX impact testing to ASTM D2512. I am aware of NASA and White Sands, but am looking for a commercial entity doing the work. No luck so far, even calling a lot of the folks on the CSA website. Any referrals will...
