Light Powers World’s Fastest Spinning Object

A dumbbell-shaped nanoparticle powered just by the force and torque of light has become the world's fastest-spinning object. Scientists at Purdue University created the object, which revolves at 300 billion revolutions per minute. Or, put another way, half a million times faster than a dentist's drill. In addition, the silica...

World’s First Hydrogen-Powered Superyacht is Here and It Is a Beauty

The world's first hydrogen-powered superyacht was unveiled last week at the Monaco Yacht Show and it made quite an impression. The model of the 367-foot yacht was the pinnacle of luxury and sophistication. The miniature model was presented by a Dutch firm called Sinot Yacht & Architecture Design. The ship,...

Securing Flight’s Clean Future with Cryogenics and Superconductivity

Joshua Feldman, a graduate student in the University of Illinois at Urbana-Champaign’s Haran Research Group, headed by Professor Kiruba Haran, is currently working to solve a rather lofty problem… literally. He and the Haran team are addressing the uncertain outcome of airline travel in an envirocentric future by developing a...

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...
