New Method Produces Hydrogen at Lower Temperatures

Waseda University (Tokyo) scientists have developed a new fast and irreversible method for producing hydrogen that requires less energy and takes place at lower temperatures. The innovation, according to the research team, is expected to contribute to the spread of fuel cell systems for automobiles and homes.

Strong Signs of Quantum Spin Observed in Ytterbium Compound

Inside a new exotic crystal cooled to near absolute zero, physicist Martin Mourigal has observed strong indications of quantum entanglement, a theory so weird Albert Einstein lampooned it as "spooky action at a distance." Entanglement occurs when two particles, such as electrons, become intimately linked to one another even when...

BESSY II Experiment Cools 10 Million Ions to 7.4 K

Scientists at BESSY II in Berlin have developed an experimental method that cooled 10 million ions to 7.4 K for the first time. The new ion trap they created provides an opportunity to use cryogenic X-ray spectroscopy to study the magnetism and ground states of molecular ions. It is also,...

Brooks Automation Acquires Cool Lab, LLC

Brooks Automation, Inc. (CSA CSM) announced on Nov. 29 that it has acquired Cool Lab, LLC, a subsidiary of BioCision, LLC. Cool Lab provides a range of innovative, patented and patent-pending applications for sample cooling and freezing, controlled rate freezing, portable cryogenic transport and archival storage solutions for temperature sensitive...

New MRI Magnet Requires only 20 Liters of Helium

GE Healthcare has announced Freelium, a magnet technology that operates with 20 liters of liquid helium compared to the 2,000 liters needed by conventional MRI magnets. Hospitals using the technology, according to GE, would no longer require the extensive venting that often necessitates siting a magnet in a separate building...

India Set to Become Associate Member State of CERN

At an event on Nov. 21, Fabiola Gianotti, CERN's director general, and Sekhar Basu, chairman of the Indian Atomic Energy Commission and secretary of India's Department of Atomic Energy (DAE), signed an agreement admitting India to CERN as an Associate Member.

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...

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...

TS diagram for helium

Where can I obtain a really big, nice TS diagram for helium ?

Reliability and mounting of electronic substrates at low temperatures

I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...

Are 3D drawings included in the sale of a cryogenic plant?

I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...

Looking for a source of LOX impact testing to ASTM D2512

I have been looking for a source of LOX impact testing to ASTM D2512. I am aware of NASA and White Sands, but am looking for a commercial entity doing the work. No luck so far, even calling a lot of the folks on the CSA website. Any referrals will...
