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,...

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.

Joule-Thomson Effect

The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under...

Current Leads

One of the challenges of using superconducting magnets is the connection of the magnet to a room temperature power supply. This is accomplished via current leads. The trick is that current leads should ideally have a low heat leak, since they connect room temperature to cryogenic temperature, while at the...

Multilayer Insulation

Multilayer insulation (also referred to as superinsulation) is a key component in the reduction of heat leak to cryogenic systems due to thermal radiation. MLI consists of a series of uncooled reflective surfaces placed in the vacuum space between two surfaces, one warmer than the other. Generally speaking, for ideal...

You are encouraged to read Cryo Central’s History...

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...

Cryogenic thermophysical property data

I am in search of information regarding cryogenic thermophysical property data, specifically, Thermal Conductivity, Thermal Expansion, Stiffness and Modulus, in the 20K range. My list of materials include: Ti-6AL-4V (ELI), Al 6061-T651, and Invar (36%, plus any other composition which might have data available). Other materials which would be helpful...
