UH wind turbine superconductivity research project wins additional funding

A University of Houston engineering researcher and his team have received additional funding from the US Department of Energy (DOE) for a wind energy project that involves using superconducting wire to generate and transport electricity.

Fermilab scientists selected as APS fellows

Five Fermilab scientists have been named fellows of the American Physical Society, a distinction awarded each year to no more than one-half of 1 percent of current APS members by their peers.

Nexans and AMSC introduce fault current limiter for North American utilities

AMSC, a global solutions provider serving wind and grid leaders, and Nexans, an expert in the cable industry (both CSA Corporate Sustaining Members), recently introduced to the North American market a medium voltage superconductor fault current limiter (SFCL) solution that is designed to meet many of the challenges caused by...

“Crowning” the ITER cryostat from below solves columnar design problem

Columns are as old as civilization: for thousands of years, they have provided architects and engineers with a simple and sturdy solution to support heavy loads while leaving room to move around on the ground below. This traditional and reliable solution was to be implemented in ITER.

DOE study: LNG exports to benefit American economy

The US Department of Energy (DOE) has released its study on the economic impacts of liquefied natural gas (LNG) exports. DOE’s analysis finds that the US economy will experience “net economic benefits” from allowing increased LNG exports. It found that the natural gas boom has helped create jobs and spur...

Science and engineering students petition Congress: Stop sequestration

Science and engineering students have hand-delivered a petition to the local offices of all US senators and House leaders, requesting that sequestration be halted because it would harm their future as innovators and hurt economic growth in the United States. The students represent numerous scientific societies across the United States,...

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...

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...
