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.

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...
