TEPCO to buy 800,000 tonnes of LNG from US

Gulfnews.com reports that the operator of Japan’s crippled Fukushima nuclear power station said Wednesday it plans to buy 800,000 tonnes of light liquefied natural gas (LNG) annually from the United States as it looks to cut its fuel bills. Tokyo Electric Power (TEPCO) said it had agreed to buy 400,000...

US conductor fabrication for ITER

US ITER and its vendors are moving into a new fabrication phase for the project's toroidal field magnet system. Cabling and conductor fabrication are now underway in New Hampshire and Florida for the niobium-tin wire produced in the US. All of this fabrication effort is in preparation for delivering the...

The birth of a very-high-field superconductor

The strong magnetic fields of an MRI scanner or a particle accelerator are generated efficiently by electromagnets that have superconducting wire in their coils. A group of scientists has discovered how to make better wires using a promising material known as Bi-2212. With this discovery comes the possibility of creating...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role.

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...
