Boeing and Rolls Royce Back Self-creating Liquid Oxygen Engine

UK-based Reaction Engines Limited REL has raised an additional £26.5 million in funding from Boeing HorizonX Ventures and Rolls Royce for its SABRE engine project. Researchers plan to begin testing the engine in 2020. Engineers designed it to produce its own liquid oxygen by cooling air entering the engine during...

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...

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 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...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Specs and info on turbo expanders

I am a fourth year chemical engineering student doing a design project for the liquefaction of natural gas to DME and we are using a turbo expansion unit. I was wondering whether you would send me some specs and any additional information on turbo expanders that I could use as...

Colleges that offer cryogenic studies

Would you happen to know of any colleges in the US that offer cryogenics as a major? If not, should I major in something like biology or physics before, then branch off to the field of cryogenics? Any information that you could give me would be greatly appreciated, considering this...

Sudden loss of vacuum in LHe storage dewar

I’m trying to find data on what happens when a 100 Liter LHe storage dewar experiences a catastrophic failure such as a sudden loss of vacuum. If anyone has any info on this subject, it would be very helpful.

Data on hardness of Indium?

Where can I find experimental data on the hardness of Indium, as a function of temperature, as well as any existing data on the thermal contact conductance of junctions containing Indium foil, also as a function of temperature?
