Scientists Discover Hidden Magnetic Waves in High-Temperature Superconductors

Scientists at the US Department of Energy's (DOE) Brookhaven National Laboratory and other collaborating institutions have discovered a surprising twist in the magnetic properties of high-temperature superconductors (HTS), challenging some of the leading theories. In a new study, published online in the journal Nature Materials on August 4, scientists found...

US Dept. of Energy approves Lake Charles LNG non-FTA export application

The Department of Energy has conditionally authorized Lake Charles Exports to export domestically produced liquefied natural gas (LNG) to countries that do not have a Free Trade Agreement (FTA) with the United States from the company's terminal in Lake Charles, Louisiana.

Former SSC site now revitalized facility

Twenty years after the closing of the former Superconducting Super Collider, it is now a revitalized facility renovated by Waxahachie chemical manufacturer Magnablend. The Ellis County site improvements were highlighted in a tour the company hosted for US Rep. Joe Barton (R-TX), who was instrumental in bringing the SSC facility...

IARPA releases solicitation for SC research in high-performance computing

US government researchers are asking industry to develop a small computer based on superconducting logic and cryogenic memory that is energy-efficient, scalable, and able to solve interesting problems—particularly those that involve intelligence gathering and analysis.

NIST seeks proposals to establish new center of excellence on advanced materials research

The National Institute of Standards and Technology (NIST) has announced a competition to create an Advanced Materials Center of Excellence to foster interdisciplinary collaborations between NIST researchers and scientists and engineers from academia and industry. The new center will focus on accelerating the discovery and development of advanced materials through...

NASA and Korean space agency discuss space cooperation

NASA Administrator Charles Bolden and the president of the Korea Aerospace Research Institute (KARI), Seung Jo Kim, met in Washington on July 29 to discuss collaboration in aeronautics research and space exploration, including KARI's robotic lunar mission and NASA's asteroid initiative.

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...

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 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...
