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...

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...

Dry ice vs. LN2 for preserving tissue

I was wondering if anyone could provide feedback/data on whether it is best in terms of preserving tissue quality to freeze tissue in OCT using dry ice versus liquid nitrogen?

Are there lists of existing biorepositories?

We are a relatively new Biorepository that was developed as part of a large breast cancer epidemiology study, and thus far we have accumulated DNA on over 8000 women along with extensive questionnaire, mammography, and case status data. I was wondering, are there lists of existing Biorepositories with their contents?...

Heat flux value for inner vessel when vacuum insulation fails

To size a relief valve for a LN2 cryostat I have to know “worse case” boil-off rate when vacuum insulation failed and inner vessel with LN2 is in direct contact with room temperature air at 300K. So, I am looking for a heat flux value (watt/m2) to LN2 inner vessel...

Trying to design a system to store ammonia at -33°C

I am working on a project where we are trying to design a system to store ammonia at -33°C. In order to size the compressors to maintain the ammonia in the liquid state, I need to estimate the heat gained from the environment including the radiation from the sun and...
