Japan minister seeks quick OK for US LNG imports

Japanese trade minister Toshimitsu Motegi called for early approval for exports of liquefied natural gas to Japan in a meeting with Acting Energy Secretary Daniel Poneman, saying securing a relatively cheap energy source is crucial for Japan, Kyodo news reported.

Oxford Instruments announces winner of 2013 Nicholas Kurti European Science Prize

Dr. Lapo Bogani from the Universität Stuttgart has been awarded the 2013 Nicholas Kurti European Science Prize. This prestigious award is sponsored by Oxford Instruments, a leading provider of high technology tools and systems for industry and research.

Physicists build world’s first ‘magnetic hose’ for transmitting magnetic fields

One of the more important properties of electromagnetic waves is that they can be transmitted over almost unlimited distance. However, the same cannot be said of magnetic fields. "The impact of magnetism in science is limited by an apparently insurmountable restriction: magnetic fields rapidly decay with the distance from the...

GE researcher receives 200th US patent

GE Global Research, the technology development arm of the General Electric Co., is honored to announce that Dr. E. Trifon Laskaris, Chief Engineer and pioneer in imaging technologies, has been awarded his 200th U.S. patent—a milestone previously reached by only one other GE research lab employee, Thomas Edison.

Chart Industries wins $45m+ LNG equipment contract

Chart Industries, Inc., an independent global manufacturer of highly engineered equipment used in the production, distribution, storage and end-use of hydrocarbon and industrial gases, has announced that its Distribution & Storage (D&S) business in China has been awarded a new contract to provide liquefied natural gas (LNG) fueling stations, self-contained...

US House passes bill to head off massive helium shortage

On April 26, the US House of Representatives passed a bill by a vote of 394 to 1 that would head off a critical shortage of helium that is sure to strike in October if Congress does nothing. That news should come as a relief to the thousands of scientists...

Latest in Defining Cryogenics

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
