Goddard Goings: When NASA Went SHOOTING Into Orbit

The ’80s have been thrust back into our collective conscious! Hits such as Tracy Chapman’s “Fast Car” and “Running up that Hill” by Kate Bush have been introduced to a new generation by an incredibly popular cover of the first song and the repetitious use of the second in a...

Quantum Design Explores Quantum Frontiers with Precision Measurements

Since 1982, Quantum Design has been providing lab-ready scientific instruments to colleges, universities, government and corporate laboratories around the world. Instruments include the DynaCool® Physical Property Measurement System (PPMS), the MPMS3® SQUID Magnetometer and VersaLab® Physics Education System. The OptiCool® is a large volume, low vibration, low temperature and high...

Under Pressure: Harvard Scientists Break Through Precise Measurement with New Tool

Hydrogen (like many of us) acts weird under pressure. Theory predicts that when crushed by the weight of more than a million times Earth’s atmosphere, this light, abundant, normally gaseous element first becomes a metal and then, even more strangely, a superconductor – a material that conducts electricity with no...

The Next Generation in Cryogenics and Superconductivity

This feature introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields. Debuted in the 2006 issue, the feature has presented many young persons whom we are proud to see have indeed lived...

Cryogenic Processors to Open Kentucky-Based Freeze-Dry and Packaging Site

Cryogenic freezing specialist Cryogenic Processors will open a new cryogenic freezing and freeze-drying facility in Paducah, Kentucky, at the end of 2024. The plant will feature three isolated pelletising rooms, each equipped with advanced blending systems and a standard conical pelletiser with an increased capacity of 1000kg per hour. Once pelletized,...

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...

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...

School science projects involving cryogenics and metallurgy?

Can you recommend any school science projects that would involve cryogenics and metallurgy?

Metallic Salts Normally Used to Produce Ultra-Low Temperatures?

Regarding the method known as the Adiabatic Demagnetization of Paramagnetic Salts: What metallic salts are normally used to produce the ultra-low temperatures used for near-absolute-zero cryogenic research? Which salts are the most efficient? Which make the best cooling agents? And which are used most commonly by physicists? I am looking...

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...
