NASA Goddard Hosts Young Women for STEM Girls Night In
Late on a Friday night, 40 high school girls arrived at NASA’s Goddard Space Flight Center in Greenbelt MD for a STEM-themed sleepover, ready to learn about careers in science, technology, engineering and math.
Dr. Roger W. Boom 1923-2018
It is with great regret that we report the death of Dr. Roger W. Boom, emeritus professor from the University of Wisconsin and mentor and inspiration to a great many leaders in the fields of cryogenic engineering and superconductivity.
Cryogenics in Medicine and Biology
The field of cryogenics has been connected with medical applications since its inception, and what follows is a historical review of some of the major applications within medicine where the term cryogenic is used in a specific manner.
DH Industries Contributes To Successful Launch of LNG Barge
The successful completion and delivery of Clean Jacksonville was announced in August, including information on the involvement of CSA member DH Industries BV.
Towards Cryogen-Free SRF Particle Accelerators
Particle accelerators have been essential tools of particle physics since initial development in the early twentieth century, with commercial applications soon following each successive advancement.

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...

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...
Company to design and manufacture a portable gas purity monitoring system
I am looking for a company to design and manufacture a portable gas purity monitoring system using a cryostat/dewar/flow meter combination.
Consultant knowledgeable in LNG
My company is seeking a consultant who is knowledgeable in LNG. It is a project located overseas, and involves a refinery and heat exchangers. Can anyone provide me with a reference?
LN2 flow in cryotherapy device
I’m working on a cooler device that will be pretty similar to the devices commonly used in cryotherapy for cooling skin.
Source for small gas liquefier/cryocooler?
I would like to acquire a used gas liquefier/cryocooler for use in my non-profit project to build a high-performance natural gas (methane) powered car. I am interested in liquefying piped natural gas (methane) into LNG (about 120K or -154 degrees).
