DOE Earmarks $39 Million for Hydrogen Fuel Cell R&D

The US Department of Energy announced up to $39 million in available funding to support early stage R&D for innovative hydrogen and fuel cell technologies. Concept papers are due May 7, 2018, and full applications will be due June 12, 2018.

MIT Spinoff Faces Challenges for its Planned Fusion Power Plant

Commonwealth Fusion Systems, an MIT spinoff based in Cambridge, aims to bring a fusion power plant online within 15 years—a timeline faster by decades than other fusion machines. The project will face a number of challenges, according to an analysis by IEEE, including fabricating and testing a new class of...

Keeping the LHC Cold

The Large Hadron Collider is colder than interstellar space thanks to its cryogenic cooling system, with liquid helium pulsing through sophisticated plumbing that runs both inside and outside of the machine.

Link Discovered Between Superconductivity and Periodic Table

Scientists from Moscow Institute of Physics and Technology and Skoltech have discovered a general principle for calculating the superconductivity of hydrides based on the periodic table alone. The result, published in the Journal of Physical Chemistry Letters came as the group explored the superconductivity of actinium hydrides.

EU Funds Research on “Cryosocieties”

The European Research Council has awarded a grant to researchers at Germany's Goethe University Frankfurt interested in understanding the social impacts of cryobiology. The research will focus on the freezing of umbilical cord blood as preparation for later regenerative therapies, the cryopreservation of egg cells for reproductive purposes and the...

New Capabilities at NSLS-II Set to Advance Materials Science

Scientists at NSLS-II's Hard X-ray Nanoprobe (HXN) beamline have demonstrated the beamline's ability to observe materials down to 10 nanometers, about one ten-thousandth the diameter of a human hair. According to the team, this exceptionally high spatial resolution will enable scientists to "see" single molecules.

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...

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...
