Hyundai Nexo Sets Hydrogen Fuel Cell Distance Record

Celebrity explorer Bertrand Piccard drove Hyundai’s Nexo SUV 484 miles across France in November, setting a new world record for the longest distance traveled in a hydrogen-powered vehicle on a single tank. Within the category of zero-emissions options, the hydrogen fuel cell is constantly being eclipsed by electric power. But...

Jefferson Lab Scientists Are Designing Accelerators that Could Help Clean the Environment

Physicists at Jefferson Laboratory are working on two accelerator designs they hope could change water treatment. It’s been 30 years since a pilot project in Miami-Dade County found that blasting wastewater with electrons could clean it up—from microorganisms to harsh chemicals. Fay Hannon is designing a low-energy, portable accelerator for...

Cryogenics Secures Volatile Car Batteries in Transit

Early in December, researchers from Warwick Manufacturing Group (WMG) at the University of Warwick UK, in collaboration with Jaguar Land Rover engineers, froze batteries with liquid nitrogen. Research suggests this would allow lithium car batteries—costly and dangerous to move—to be transported safely in a much cheaper and environmentally friendly way.

Electronic Map Reveals ‘Rules of the Road’ in Superconductor

In a study published in the American Physical Society journal Physical Review X (PRX) in early December, Rice University physicist Ming Yi and colleagues offer up a band structure map for iron selenide, a material that has long puzzled physicists because of its structural simplicity and behavioral complexity. The “roadmap,”...

Tour ITER in Virtual Reality

ITER, the world’s largest fusion tokamak, is currently under construction in southern France. Now, operational facilities are under construction including the First Plasma plant and tokamak building. The consortium, comprising representatives from 35 nations, has introduced an interactive worksite tour to keep the public informed on site progress and encourage...

European Space Agency Approves Record Budget To Meet New Challenges

European Space Agency (ESA) members approved a record $15.97 billion budget in late November in Seville, Spain, to secure Europe's position in space exploration as the United States and China press ahead. Funding will allow ESA a full series of programs and additional scientific work including increased Earth observation to...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
