Is magnetic cooling the future of cool?

Ames Laboratory scientists almost 20 years ago announced groundbreaking progress in magnetic refrigeration and yet there are still no known commercially available products that use a magnetic cooling system. Magnetic cooling exploits the magnetocaloric effect, a temperature change of a material caused by exposing it to a changing magnetic field,...

Master Bond announces new one component epoxy

Master Bond on October 13 unveiled a new single part adhesive sealant for use in a variety of applications in aerospace, electronic, optical, specialty OEM and related industries. The Master Bond Supreme 10HTF-1 offers cryogenic serviceability from 4K to +400°F and resists an array of chemicals such as water, fuels,...

New atomic absorption spectrometer helps redefine the kelvin

A team of Australian scientists has developed an atomic absorption spectrometer that provides a new way to determine Boltzmann’s constant, a number that relates the motion of an individual atom to its temperature. The research, published in Nature Communication contributes to a worldwide scientific effort to redefine the kelvin, the...

DOE announces new accelerator stewardship funding opportunities

The US Department of Energy made available an estimated $4 million in grants on October 13 with a Funding Opportunity Announcement (FOA) for research opportunities associated with its Accelerator R&D Stewardship Program. Research funded under this FOA could lead to advances is High Energy Physics (HEP), but the grants are...

2015 Nobel Prize in Physics awarded to neutrino oscillation experimenters

The Royal Swedish Academy of Sciences on October 6 awarded the 2015 Nobel Prize in Physics to Takaaki Kajita and Arthur B. McDonald in recognition of key contributions each made to experiments demonstrating neutrino oscillations. Physicists struggled for decades prior to Kajita's and McDonald's experiments to explain why up to...

CONCOA opens new facility in Taiwan

CONCOA has opened its second marketing facility and product support center in the Pacific region, an area the firm sees as strategic for investment and trade. Located in the greater Taipei area, the new facility supports business partners in China, Hong Kong, Japan, Macao, South Korea and Taiwan.

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

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...

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.
