Electrons and Liquid Helium Advance Understanding of Zero-Resistance

Research conducted by the Quantum Dynamics Unit at Okinawa Institute of Science and Technology Graduate University (OIST) in Japan could represent an important step in understanding two-dimensional semiconductors. The unit's latest paper, published in "Physical Review Letters", describes anomalies in the behavior of electrons in an electrons-on-liquid helium two-dimensional system.

Brooks introduces p-Chip Technology for More Reliable Sample Tracking and Security

Brooks Automation (CSA CSM), a global provider of automated sample storage systems and consumables for compound management and biorepositories, has introduced its first commercial sample storage tube incorporating p-Chip® tracking technology. The p-Chip, a unique electronic microtransponder ID tagging technology, is 100 times smaller, far less expensive and more reliable...

Heavy fermions get nuclear boost on way to superconductivity

Physicists from the United States, Germany and China have discovered nuclear effects that help bring about superconductivity in ytterbium dirhodium disilicide (YRS), one of the most-studied materials in a class of quantum critical compounds known as "heavy fermions." The discovery marks the first time that superconductivity has been observed in...

Metamaterials Boost Sensitivity of MRI Machines

A group of researchers from Russia, Australia and the Netherlands have developed a technology that can reduce Magnetic Resonance Imaging (MRI) scanning times by more than 50 percent, allowing hospitals to drastically increase the number of scans without changing equipment. Scientists achieved this leap in efficiency by placing a layer...

Scientists push boundaries of antimatter research in quest for answers

Scientists of the international ALPHA Collaboration have pushed the boundaries of antimatter research with a breakthrough studying the properties of antihydrogen. Published in the journal Nature, the collaboration's result improved the measurement of the charge of antihydrogen, essentially zero, by a factor of 20. The work is the latest contribution...

New Dream Team Leading CERN

Fabiola Gianotti officially began her term as CERN's new—and first female—Director General on January 1, bringing with her a group CERN describes as a "new dream team." Gianotti earned her PhD in experimental particle physics from the University of Milan in 1989 and joined CERN as a researcher in 1994....

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
