Superconductivity: Will It Be Coming in from the Cold?
Dr. Paul Michael Grant assesses the application of superconductivity within the electric power sector, asking, "Is there a 'hot track' upward for both applications of today's superconductors and future transition temperatures beyond 200K as well?"
ASC Attendees Spend Event-Filled Week
This year’s Applied Superconductivity Conference, ASC14, hosted 1,523 attendees from 36 countries, with 791 papers submitted for peer review. Held at the Charlotte NC Convention Center, August 10-15, the event’s theme was “Race to Energy Efficiency,” incorporating the racecar theme of its proximity to the NASCAR Hall of Fame, which...
Historical Retrospective: CSA’s Birth in the Early Days of the Space Age
We’ve always heard that CSA began in 1964 with the growing need for cryogenics in the burgeoning Space Age. We decided to take a look at the unfolding of this phenomenon in the pages of Cryogenic Technology, “the Journal of the Cryogenic Society of America,” Volume 1, 1964-1965.
ICEC25/ICMC2014 Held at University of Twente, the Netherlands
The 25th International Cryogenic Engineering Conference and International Cryogenic Materials Conference took place July 7-11 at the University of Twente, Enschede, the Netherlands.
The 18th International Cryocooler Conference
The 18th International Cryocooler Conference was held June 9-12 in Syracuse NY at the beautiful Syracuse University campus. Conference Chairman Rich Dausman and Co-chairman Dr. Chao Wang, both of Cryomech, Inc., hosted 161 attendees, including 11 students and six retirees, representing 14 different countries.

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...
Wind Tunnels
Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...
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 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.
