Worthington Introduces Carbonation Cylinders

Worthington Industries, Inc. is expanding its cryogenic technology portfolio with the introduction of a proprietary-designed beverage carbonation cylinder for industrial gas markets. The company says it designed the 500-pound beverage carbonation cylinder for use in the food and beverage markets, including restaurants, bars, movie theaters, stadiums and other locations where...

FSU Prof Explores Outer Regions of Periodic Table

In a specially designed lab at Florida State University, chemistry professor Thomas Albrecht-Schmitt studies radioactive berkelium, a little known—and difficult to obtain—element on the fringes of the periodic table that he says could help broaden the fundamental understanding of chemistry.

Air Products Celebrates Heat Exchanger Roll Out

Air Products, a leader in liquefied natural gas technology and equipment, celebrated this month the rollout of the first completed LNG heat exchanger manufactured at its new production facility in Manatee County, Florida, a 300,000 square foot space that doubles the company's manufacturing capacity.

Atlas Copco Acquires Leybold Vacuum

Atlas Copco AB has acquired Oerlikon Leybold Vacuum GmbH, a pioneer of vacuum technology founded in 1850. Renamed Leybold GmbH, the company joins the vacuum solutions division at Atlas, expanding the group to over 6,500 employees in more than 35 countries.

Undergrads Construct Cryogenic Star-Tracking Instrument

A team of undergraduates from the Rochester Institute of Technology (RIT) will soon deploy its Cryogenic Star Tracking Attitude Regulation System, a telescope and camera based “compass” for rockets that will orient the payload based on the images of stars. CSTARS uses a new kind of detector technology and will...

19th International Cryocooler Conference

A group of 180 researchers and engineers from 12 countries gathered in San Diego June 20-23 for the 19th International Cryocooler Conference (ICC19), coordinated by the NASA Jet Propulsion Laboratory (JPL) and held at the Town and Country Resort and Convention Center. The conference included a combination of 80 oral...

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...

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...
