Chart Acquires Skaff Cryogenics

Chart Industries, Inc. announced its acquisition of Skaff Cryogenics and Cryo-Lease, LLC in early January. The acquisition, according to Chart, expands the company's direct regional presence for service and aftermarket support in the Northeast United States.

Dippin’ Dots Launches Cryogenic Company

Dippin' Dots, known for its popular flash frozen beaded ice cream, welcomed the new year with the launch of Dippin' Dots Cryogenics, LLC, an offshoot designed to leverage its intellectual property in cryogenic processes and machinery.

Common Oxygen Catalyst Soaks Up Hydrogen Too

Scientists at Oak Ridge National Laboratory (CSA CSM) have discovered that an oxygen sponge used in vehicle exhaust systems to soak up oxygen from air and store it for later use may also be a hydrogen sponge. The finding, according to the researchers, may pave the way for the design...

SESAME Delivers Its First Light

Scientists at SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) recorded first monochromatic light through the XAFS/XRF spectroscopy beamline in November, signaling the start of the laboratory’s experimental program. The beamline, SESAME’s first to come on stream, delivers X-ray light that will be used to carry out...

FAST Electron Beam Achieves Milestone Energy

In November, a team at the Fermilab Accelerator Science and Technology (FAST) facility ramped up a beam of electrons to 300 million electronvolts, a double milestone event, according to the lab. For one, the beam surpassed the threshold needed to launch a new accelerator physics program at Fermi National Accelerator...

Argonne Welcomes GRETINA Back Home

A world-class gamma ray spectrometer called GRETINA has returned to Argonne National Laboratory (CSA CSM) for a second run expected to last 18 months. Scientists will use the instrument in conjunction with Argonne’s Fragment Mass Analyzer, where it will enable studies of nuclei at or near the proton drip line...

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...
