Winners Announced for 2017 Fritz London Memorial Prize
Duke University has announced recipients of its 2017 Fritz London Memorial Prize, choosing Jeevak Parpia of Cornell University and William P. Halperin and James A. Sauls, both from Northwestern University.
Boiloff Calorimetry for the Measurement of Very Low Heat Flows
The use of boiloff calorimetry to measure the effects of thermal energy (or heat) dates back to the early 1900s [1, 2]. Gas flow rates measured in evaporation—or boiloff—calorimetry enable direct calculation of quantities such as heat flux and thermal conductivity. A particularly useful approach is to use nitrogen for...
Remembering the 1987 Woodstock of Physics
Paul Michael Grant was in the room where it happened, and in this essay, he recalls the 1987 APS March Meeting known as the "Woodstock of Physics." It began when Brian Maple, of UC San Diego, took the unprecedented and ambitious step of assembling an “off the program” all night...
Women in Cryogenics and Superconductivity
CSA celebrates women in cryogenics and superconductivity. In this feature, six women in positions across the industry discuss current projects, how they entered the field and their thoughts on attracting more women to the profession.
Cryogenic Sapphire Oscillator Enhancement Improves Accuracy
Researchers from the University of Adelaide in South Australia have enhanced the Cryogenic Sapphire Oscillator, or Sapphire Clock, to allow time measurements with accuracy on the femtosecond scale. The oscillator has a five-centimeter cylinder-shaped sapphire crystal cooled to about -267°C, or about five or six degrees above absolute zero. At...

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...

You are encouraged to read Cryo Central’s History...
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...
Specs and info on turbo expanders
I am a fourth year chemical engineering student doing a design project for the liquefaction of natural gas to DME and we are using a turbo expansion unit. I was wondering whether you would send me some specs and any additional information on turbo expanders that I could use as...
Colleges that offer cryogenic studies
Would you happen to know of any colleges in the US that offer cryogenics as a major? If not, should I major in something like biology or physics before, then branch off to the field of cryogenics? Any information that you could give me would be greatly appreciated, considering this...
Sudden loss of vacuum in LHe storage dewar
I’m trying to find data on what happens when a 100 Liter LHe storage dewar experiences a catastrophic failure such as a sudden loss of vacuum. If anyone has any info on this subject, it would be very helpful.
Data on hardness of Indium?
Where can I find experimental data on the hardness of Indium, as a function of temperature, as well as any existing data on the thermal contact conductance of junctions containing Indium foil, also as a function of temperature?
