UCSB researchers make headway in quantum information transfer

Fiber optics has made communication faster than ever, but the next step involves a quantum leap—literally. In order to improve the security of the transfer of information, scientists are working on how to translate electrical quantum states to optical quantum states in a way that would enable ultrafast, quantum-encrypted communications.

GE expands small-scale LNG business

In connection with its recent acquisition of substantially all the assets of the Salof Companies, GE Oil & Gas announced that it has completed its acquisition of a 50 percent ownership interest in Beijing enCryo Engineering Co., Ltd., a Beijing-based joint venture with Beijing Maison Engineering Co., Ltd. that specializes...

Scientists expand search for light dark matter

After seeing possible hints of surprisingly light dark matter earlier this year, scientists on the Cryogenic Dark Matter Search have found a way to improve their search for such particles.

Fermilab postdoc wins IEEE Particle Accelerator Science and Technology Award

Dr. Anna Grassellino of Fermi National Accelerator Laboratory has been awarded the Particle Accelerator Science and Technology Doctoral Student Award. Sponsored by the IEEE Nuclear and Plasma Sciences Society, it is given to individuals who have performed outstanding thesis research in particle accelerator science and technology.

SuperPower wire powers European Union ECCOFLOW

SuperPower Inc., a subsidiary of Furakawa Electric Company of Japan, has announced that it provided the second-generation high temperature superconducting (2G HTS) wire for the European Union (EU) collaboration program, called Project ECCOFLOW, that will demonstrate a new Superconducting Fault Current Limiter (SFCL) device capable of strengthening and protecting the...

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...

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?
