High-temperature superconductivity starts with nanoscale electronic oases
High-temperature superconductivity doesn't happen all it once. It starts in isolated nanoscale patches that gradually expand until they take over.

Leading physicist becomes executive director of NINT
An expert in nano-electronics will lead Canada’s National Institute for Nanotechnology (NINT) into its second decade. The NINT governing council has named Dr. Marie D’Iorio as its new Executive Director.
NIST physicists benchmark quantum simulator with hundreds of qubits
Physicists at the National Institute of Standards and Technology (NIST) have built a quantum simulator that can engineer interactions among hundreds of quantum bits (qubits)—10 times more than previous devices.
CMS discovers new particle
The Compact Muon Solenoid (CMS) experiment at CERN has submitted a paper for publication describing the first observation of a new particle, an excited beauty baryon called the ?b*0 (?b is pronounced "Csai - bee").
Test facility at KEK becomes an accelerator
On April 13 at KEK’s superconducting radio frequency test facility (STF), researchers successfully transported beam to the beam dump. The dump, located in the last part of the accelerator, is designed to absorb the energy of particles within accelerated beam. Now STF is no longer a test facility: it is...
New Light Source construction more than 70 percent complete
Construction of the $912-million National Synchrotron Light Source II (NSLS-II) at the U.S. Department of Energy’s Brookhaven National Laboratory is more than 70 percent complete – on schedule and on budget.

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...
History of Cryogenics
From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...
Cryobiology
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. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...
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...
Cryogenic processing for medical equipment, mining industry
Greetings from Australia. I am looking for a company that I might contact that has any experience or has done any research into cryogenic processing for medical equipment, in particular, joint prosthesis.
