Bruker and Oxford Reach Deal for Superconducting Wire Business

The Bruker Corporation has closed a deal with Oxford Instruments for the $17.5 million acquisition of Oxford's Superconducting Wire LLC (OST). In the transaction, Bruker Energy and Supercon Technologies, Inc. (BEST), a Bruker subsidiary, acquired all shares of OST and announced the intent to fold the Carteret NJ based company...

Gecko-Inspired Adhesive Withstands Extreme Temperatures

Researchers have developed a new dry adhesive that bonds in temperatures ranging from -320°F to 1,832°F, a quality that could make the product ideal for space exploration where shade can be frigid and exposure to the sun blazing hot. It features vertically aligned carbon nanotubes with tops bundled into nodes...

LCLS X-ray Laser Reveals Ultrafast Riboswitch in Action

Scientists have used the powerful X-ray laser at the Linac Coherent Light Source (LCLS), located at the Department of Energy’s SLAC National Accelerator Laboratory, to take the first ever snapshots of an ultrafast riboswitch, a gene regulator that can switch individual genes on and off. According to the research team,...

Stanford Study Suggests Battery Power Will Trump Hydrogen Fuel Cells

Stanford researchers say communities would be better off investing in electric vehicles that run on batteries instead of hydrogen fuel cells, in part because a hydrogen infrastructure provides few additional energy benefits for communities beyond clean transportation.

CoEPP and IHEP to Collaborate on Future Experiments

At a ceremony held Nov. 8 in Beijing, representatives from the ARC Center for Particle Physics at the Terascale (CoEPP) and the Institute of High Energy Physics (IHEP) signed a Memorandum of Understanding to establish scientific exchange, collaboration and cooperation between the two organizations.

Cooling Technique Improves Antiproton Mass Measurement

Scientists from CERN's ASACUSA experiment have announced a new precision measurement of the mass of the antiproton relative to that of the electron, a result based on spectroscopic measurements of approximately two billion antiprotonic helium atoms cooled to temperatures near absolute zero.

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...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
