New Thermometer Measures Cryogenic Temperatures at Submicron Scales
Taking the temperature of a sample can be tricky—especially in the regimes of the very small and the very cold. The smaller the sample, the greater the influence the thermometer itself may exert on the measurement. And in the ultracold regime, even tiny amounts of heat can significantly alter the...

Nanoparticles Show Quick and Easy Way to Target Cancer
Researchers have been exploring the use of injectable nanoparticles that can quickly home in on a microscopic tumor. It’s a novel technique that could pave the way for the early detection of small tumors that may not show up on traditional imaging technologies. In a study published in the October issue of...
Researchers Simplify Switching for Quantum Electronics
A quantum cousin of the Hall effect could open the door to energy-efficient electronics, better sensors, and more-powerful quantum computers. Researchers have now broken a key barrier to its practical application by controlling the phenomenon electrically, rather than magnetically, for the first time. The Hall effect, discovered by physicist Edwin...
Firefly Aerospace Awarded Multi-Launch Agreement with L3Harris
Firefly Aerospace, Inc., an end-to-end space transportation company, today announced it signed a multi-launch agreement with L3Harris Technologies for three dedicated launches on Firefly’s Alpha vehicle in 2026. With the capability to launch more than 1,000 kg to low Earth orbit, Firefly’s Alpha vehicle provides affordable, responsive, and reliable launch...

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...

Liquefied Natural Gas
Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...
Manufacturer for a machine to liquefy natural gas or methane gas.
I’m in search of a company to manufacture a machine to liquefy natural gas or methane gas.
Need a plastic for diffuser on the magnet end of a LHe fill siphon
I am trying to select a plastic to be used as a diffuser on the magnet end of a LHe fill siphon. Can you recommend anything that will hold up at LHe temps? I have seen some and they look like HDPE or Polypropylene but I am not sure.
Thermal conductivity orthotropic properties from 300K up to 500K
I am looking for the thermal conductivity orthotropic properties from 300K up to 500K (or even higher, if available). “Cryocomp” provides orthotropic data on G-10 (Fill, Warp, Normal) only up to 300K.
Looking for heat conductivity values of CuCrZr in the low temperature range of 4 to 300K
I’m a student of physical engineering and I am looking for heat conductivity values of CuCrZr in the low temperature range of 4 to 300K. Jakub Voňka Brno University of Technology Faculty of Mechanical Engineering
