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...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired,  Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere.  On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
