O”H” What a Feeling, Toyota Introduces Hydrogen Powered Semi

Toyota has announced a new zero-emission hydrogen fuel cell system designed for semi-truck use at the Port of Los Angeles. Dubbed "Project Portal," the proof of concept vehicle was unveiled at a press conference with port officials and representatives from the California Air Resources Board and the California Energy Commission....

European XFEL Commissions Its Particle Accelerator

The European XFEL has successfully commissioned the particle accelerator that will drive its X-ray laser. When fully operational, the research facility will produce up to 27,000 X-ray laser flashes per second, each so short and intense that researchers can make pictures of structures and processes at the atomic level. The...

ICHEP Publishes 2016 Proceedings

Professor Young-Kee Kim, chair of ICHEP 2016 and professor of physics at the University of Chicago, has announced that proceedings from the high energy physics conference have been published online. The proceedings are organized by session topic and include full PDFs from presenters and research teams.

Microsoft and Rambus Extend Cryogenic Memory Collaboration

Microsoft and Rambus Inc. have expanded a research collaboration begun in 2015 to develop prototype systems that optimize computer memory performance at cryogenic temperatures. The new agreement extends joint efforts to enhance memory capabilities, reduce energy consumption and improve overall system performance.

GOES-S Undergoes Thermal Vacuum Testing

In March, engineers at Lockheed Martin Space Systems lifted NOAA's Geostationary Operational Environmental Satellite-S (GOES-S) into a thermal vacuum chamber to begin testing its ability to function in the cold void of space at its orbit 22,300 miles above the Earth. To simulate the environment of space, researchers removed air...

Hybrid Airships to Transfer Helium from Tanzania

Helium One, a company that holds a prospecting license for recently discovered helium deposits in Tanzania, intends to use Lockheed Martin's LMH-1 hybrid airships to transport the gas out of the country. The company's license includes three project areas in Tanzania, encompassing more than 4,500 km² of land with helium...

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...

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...

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
