New Report Buffers Possibility for Molecular Level Data Storage

New research from the University of Manchester (UK) suggests that storing data with a class of molecules known as single-molecule magnets is more feasible than previously thought. The result, published in Nature, shows that magnetic hysteresis, a memory effect that is a prerequisite of any data storage, is possible in...

Brooks Automation Expands Stored Sample Monitoring

Brooks Automation, Inc. (CSA CSM) has acquired FreezerPro® and other assets from RURO, Inc., a Maryland-based developer of computer software for research, biotechnological, pharmaceutical, healthcare and government laboratories. The software enables web-based access to information on stored samples from any location on any device.

EASITrain to Hire, Fund PhD Candidates in Superconductivity and Related Fields

CERN has announced its European Advanced Superconductivity Innovation and Training project (EASITrain), a four-year initiative that brings together leading research institutes and industrial partners to train the next generation of researchers. It will cover the development of 15 Early Stage Researchers (ESRs) on projects related to superconducting wires, superconducting thin...

Electronic Symmetry Breaking Common in Superconducting Materials in High Magnetic Fields

Researchers from the Los Alamos National Laboratory report that the phenomenon of electronic symmetry breaking is common in superconducting materials in high magnetic fields. Using transport measurements near the field-tuned quantum critical point of CeRhIn5 at 50 Tesla, the researchers observed a fluctuating nematic-like state in which the material’s electrons...

UA Researchers to Design New Cryogenic Focal Plane Arrays

The American Institute for Manufacturing Integrated Photonics (AIM Photonics), a public-private partnership advancing the nation’s photonics manufacturing capabilities, has chosen a University of Arizona research team to design, fabricate and test new PIC-based datalinks for cryogenic focal plane array (FPA) readout. The project, according to AIM Photonics, has the potential...

SQUID Detector Reaches New Sensitivity Levels

Investigators at the University of Colorado, Boulder, and the National Institute of Standards and Technology (NIST) have developed a new sensor-array-based instrument that offers ultralow noise detection of small amounts of energy for a number of applications. The new device permits the collection of data from many more detectors than...

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...

Cryogenic Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...

Information on how the emissivity of the panel changes with air fouling?

I work at a facility with a large thermal vacuum chamber. We are using both nitrogen and helium shrouds.

In search of a calculation for designing a cryostat

I am a final year physics student at the University of Birmingham, and as part of a group I am currently designing a cryostat. One of the calculations I need to make (very soon!) is how much heat will be conducted down the walls. All information I have found so...

Safety of ethylene glycol and pressurized oxygen

We are reviewing the product design of liquid filled differential level gauges and want to insure that they meet the industry requirements. The former license owner had authorized that a fill fluid of ethylene glycol (68%) and distilled water (32%) could be used for oxygen service up to 500 psi....
