Saint-Gobain Seals Releases Special Technical White Paper Exploring Critical Factors of Seal Selection in Cryogenic Space Applications

Saint-Gobain Seals has released a special technical white paper for engineers and manufacturers in the space industry titled “Sealing Solutions in Critical Cryogenic Applications: Going Beyond Leakage Rate,” describing key as well as overlooked factors related to seal selection for core systems in extreme environments such as cryogenic fuel tanks...

Hydrogen Fuel Cell-powered Drone Sets New Flight Time Record

A new Guinness World Record for the longest multi-rotor flight time was achieved by South Korean company MetaVista (CSA CSM) using Intelligent Energy’s 800W fuel cell power. The quadcopter drone flew for 12 hours, 7 minutes and 5 seconds using liquid hydrogen to fuel the module.

Yale Experiment Features Quantum Physics in a Liquid

For the first time, Yale physicists using liquid helium directly observed quantum behavior within the vibrations of a liquid body. A great deal of ongoing research is currently devoted to discovering and exploiting quantum effects in the motion of macroscopic objects made of solids and gases, so this new experiment...

DOE Announces Graduate Student STEM Awards

The US Department of Energy’s (DOE) Office of Science Graduate Student Research (SCGSR) program announced 70 awards to be distributed to students at 52 universities in the US that focus on doctoral degrees in physical sciences. The aim of the awards program is to prepare graduate students for science, technology,...

Russian Physicists Obtain Data on Particle Self-organization in Ultracold Dusty Plasma

Physicists in Russia recently investigated the behavior of particles in dusty plasma at a temperature below 2 K, an experiment that revealed nanoclusters forming in the plasma and the synthesis of polymer fibers taking place at extremely low temperatures. According to the team, such results can be used to create...

Electron Camera at SLAC Films High-speed Molecular Movie

Researchers using an extremely fast electron camera at the Department of Energy’s SLAC National Accelerator Laboratory have made the first high-definition “movie” of ring-shaped molecules breaking open in response to light.

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 Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...
