New Study Reveals When a Superconductor Truly Becomes Super

Unraveling the mystery of superconductivity at high temperatures, specifically in copper oxide materials, remains one of the most puzzling challenges in modern solid-state physics. But new multinational research has confirmed the existence of a copper-oxide-based (or cuprate) phase transition at a temperature close to absolute zero (-273°C).

SPHEREx Mission Selected to Uncover Origins of the Universe

NASA's Astrophysics Explorers Program and associated divisions are moving ahead with a new space mission designed to help astronomers understand both how our universe evolved and how common the ingredients for life are in our galaxy’s planetary systems.

New Ceramic Material Can Better Withstand Extreme Temperatures

UCLA researchers and joint collaborators have created an extremely light and very durable ceramic aerogel, a new material that could be used for applications like insulating spacecraft due to its ability to withstand severe temperature changes encountered on space missions.

CERN Focused on Transforming LHCb and Upgrading ALICE

A period of maintenance and upgrade work is well underway at CERN, part of a technical break called Long Shutdown 2. Planned LS2 projects involve either upgrading or replacing sub-detectors at ALICE, while the Large Hadron Collider team is focused on increasing the proton–proton collision rate at LHCb by a...

Success after a Three-year Sprint

ProtoDUNE scientists rushed to develop the project’s first large prototype detector, resulting in an amazing display of the technology being created for the Deep Underground Neutrino Experiment.

UCSD Students Prepared to Launch Vulcan II

A team of engineering students from UC San Diego has developed a test rocket that features a 3D printed engine that incorporates liquid oxygen and kerosene RP-1. The updated rocket is called Vulcan II, and represents a vessel the students will attempt to launch roughly six miles into the atmosphere...

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...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

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...
