Cryotreating Strengthens Anti-Embolism Stockings for Cancer Patients

Anti-embolism stockings are designed to promote healthy blood flow and prevent blood clotting. The cost can range from $50 to $200 and they wear out quickly, leading to more expense. To ease the financial burden on cancer patients, Circle City Cryogenics in Indianapolis has developed a cryotreating process that improves...

“Hospital” Preserves Coral with Cryogenics

Researchers at the Taiwan Coral Reef Society have established a biopreservation and treatment center for coral reefs. Analogous to a human hospital, “sick” corals are diagnosed either in situ or in the hospital's diagnostic clinic to determine the cause of the illness. Corals are “treated” and returned to their home...

Containing Hydrogen in a Materials World

The Hydrogen Materials Compatibility Consortium—or H-Mat—is conducting early-stage research to understand how hydrogen affects the polymers and metals used in infrastructure to store, transport, compress and dispense the fuel. The consortium’s goal is to improve the reliability and durability of materials used in hydrogen infrastructure while also identifying alternative, less...

New Plane Can Fly 500 Miles Powered Entirely by Hydrogen

ZeroAvia, the California startup that designed a hydrogen-fueled electric powertrain for a hydrogen-powered six-seat plane, has been testing the technology during the past year to reduce emissions from air travel. With August’s successful flight, it expects to begin supplying the powertrain for planes carrying 20 passengers for up to 500...

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

Air Separation and Liquefaction

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...

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?
