DOE to Invest $30 Million in Hydrogen and Fuel Cells

The Department of Energy has announced its intent to invest $30 million to advance fuel cell and hydrogen technologies. Associated projects, subject to appropriations, will leverage national lab consortia launched under DOE’s Energy Materials Network (EMN) this past year and will support President Obama’s Materials Genome Initiative and advanced manufacturing...

Hydrogen Power Ruled Feasible for High-Speed Ferry

Nearly two years ago, Sandia National Laboratories researchers Joe Pratt and Lennie Klebanoff set out to answer one not-so-simple question: Is it feasible to build and operate a high-speed passenger ferry solely powered by hydrogen fuel cells? The answer is yes.

CGA Announces New Process Safety Committee

In an email to its members, the Compressed Gas Association announced the formation of a new Process Safety Committee to address process safety concerns and gaps that affect the industrial gas industry.

Auguste Acquires Taylor-Wharton’s European Operations

Auguste Cryogenics SK s.r.o. has acquired Taylor-Wharton International’s European Operations, including a cryogenic pressure vessel manufacturing facility, Taylor-Wharton Slovakia s.r.o., and the related warehouse and office complex of Taylor-Wharton Germany GmbH. Auguste says all employees have been retained and that the facilities will continue to operate under the Taylor-Wharton brand...

XFEL Commissions New X-ray Laser

Engineers at European XFEL, a large international research facility with 11 European member countries, have begun commissioning a 3.4-km-long underground X-ray laser. When operational, the laser will generate extremely short and bright X-ray light flashes that will enable new views of the structure and fast processes of the nanocosmos. Applications...

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

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...

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?
