Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

This Quantum Computer With a 3D Chip Is Heading into the Cloud

A startup in the UK is now offering cloud-based access to its own superconducting quantum computer – but with a twist that it hopes could one day help it compete against the processors developed by quantum giants such as IBM and Google.

Physicists Uncover Secrets of World’s Thinnest Superconductor

Physicists from across three continents report the first experimental evidence to explain the unusual electronic behavior behind the world’s thinnest superconductor, a material with myriad applications because it conducts electricity extremely efficiently. In this case, the superconductor is only an atomic layer thick.

Energycane Produces More Biodiesel than Soybean at a Lower Cost

Bioenergy from crops is a sustainable alternative to fossil fuels. New crops such as energycane can produce several times more fuel per acre than soybeans. Yet, challenges remain in processing the crops to extract fuel efficiently.

Lockheed Martin, Omni Tanker, UNSW to Develop Cryogenic Tank Solutions for Liquid Hydrogen

Omni Tanker, Lockheed Martin and the University of New South Wales have joined forces to develop technology that solves the challenges of transporting and storing liquid hydrogen. The group hopes to utilize two home-grown technologies to solve the challenges for the storage of liquid hydrogen with applications on ground, in...

SOFIA Upgrading One-of-a-Kind Camera

After making numerous discoveries about how magnetic fields shape our universe, an instrument flying on board the Stratospheric Observatory for Infrared Astronomy (SOFIA, Cold Facts Volume 35, Number 5), is about to get even faster at gathering data. Announced April 23, SOFIA is upgrading the High-resolution Airborne Wideband Camera-Plus, or...

Build a High Resolution Microscope From LEGO, Affordable Phone Parts

Researchers from the Universities of Göttingen and Münster have succeeded in building a high-resolution microscope using nothing more than children’s plastic building bricks and affordable parts from a mobile phone. They then went on to show that children aged 9-13 had significantly increased understanding of microscopy after constructing and working...

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?
