First APAs Delivered for ProtoDUNE Detectors

The first prototype Anode Plane Assemblies (APAs) for ProtoDUNE have arrived at CERN, where two large liquid argon detectors are under construction to test the engineering specifications for the US-based Deep Underground Neutrino Experiment (DUNE). Scientists will use the APA screens to record streaks of ionization charge inside the detectors.

WSU Recreates Titan Seas for NASA Submarine Mission

NASA's Cassini spacecraft ended its exploration of Saturn in 2017, but the space agency is already planning a more immersive return mission, aiming to plunge a submarine into the seas of Titan, the largest of Saturn’s many moons. Researchers at Washington State University are working with NASA, replicating the moon's...

Cryo-EM Advances Fight Against Hepatitis B

Indiana University researchers used cryo-electron microscopy to make an important step forward in the design of drugs that fight the hepatitis B virus, known to cause liver failure and liver cancer. A vaccine exists, but there is no cure. The study explains how the structure of the hepatitis B virus...

Physicists Create New Form of Light

A research team led by scientists at MIT and Harvard has observed groups of three photons interacting and, in effect, sticking together to form a completely new kind of photonic matter. The behavior could open a path toward using photons in quantum computing, according to the team, or even more...

Physicists Discover New Type of Quantum Material

An international team of researchers led by physicists at Rice University has stumbled upon a theoretical result that could help experimental physicists create a "Weyl-Kondo semimetal," a quantum material with an assorted collection of properties seen in disparate materials like topological insulators, heavy fermion metals and high-temperature superconductors.

Both Frozen and Fresh Embryos Offer Similar Chances of Baby after IVF for Most Women

For women using in vitro fertilization to have a child, using either fresh or frozen embryos results in similar success rates for most women, according to an international team of researchers.

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...

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...
