USC’s New Cryogenic Electron Microscopy Facility Officially Opens for Business

USC’s new cryogenic electron microscopy (cryo-EM) facility, featuring state-of-the-art instrumentation capable of imaging molecules, garnered the spotlight during a recent symposium celebrating the facility’s official grand opening. Scientists and officials from USC, biotechnology giant Amgen, Thermo Fisher Scientific, and noted academic research institutions gathered for the event, held in March at...

Ultra-lightweight Cryogenic Tank Aids Aircraft Industry Endeavors

California-based firm HyPoint is developing an innovative cryogenic tank design that could massively boost the range of hydrogen-powered aircraft, a press statement reveals. HyPoint’s technology is extremely lightweight compared with traditional fuel cells and it could allow airliners to fly up to four times farther than traditional passenger aircraft. A 50-56 passenger...

Elusive superconducting-transition signature seen for the first time

Researchers in the US report that they have observed the so-called “fourth signature” of superconducting phase transitions in materials known as cuprates. The result, obtained via photoemission spectroscopy of a cuprate called Bi2212, could shed fresh light on how these materials, which conduct electricity without resistance at temperatures of 77...

Webb Telescope’s Coldest Instrument Reaches Operating Temperature

NASA’s James Webb Space Telescope will see the first galaxies to form after the big bang, but to do that its instruments first need to get cold – really cold. On April 7, Webb’s Mid-Infrared Instrument (MIRI) – a joint development by NASA and ESA (European Space Agency) – reached its...

Multiphoton Generator on a Chip

Producing entangled photons whose properties are interdependent is key to several quantum communication technologies. Most techniques for generating these photons make them exclusively in pairs, and those that can produce more than two photons are difficult to implement. But researchers have now made a chip-sized device that can generate bunches...

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...

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?...

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...
