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...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

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...
