The discovery, described in a paper published in Nature, may provide key insights into the workings of high temperature superconductors.
Fermilab Welcomes Baby Bison with Naming Puns
Fermilab welcomed its first baby bison of 2016 on April 26 and by the next day a herd of its social media followers were birthing puns in a tongue-in-cheek #BisonNaming contest. Fermilab suggested the first name, Neil EatdeGrasse Bison, and followers took it from there. Suggestions included Higgs Bison, Bisotron, Quarky, Graze Pascale and MiniBisoNe.
Researchers Look to Super-Spintronics for Future Computing
A University of Cambridge led project aims to develop a new architecture for future computing based on superconducting spintronics. Researchers on the project, dubbed Superspin, say it will pave the way for a new generation of ultralow power supercomputers capable of processing vast amounts of data at a fraction of the energy consumption of comparable facilities.
The Brayton cycle is one of the many thermodynamic cycles used to generate cooling at cryogenic temperatures. Strictly speaking, when referring to cooling we should call this the reverse Brayton cycle as the original Brayton cycle describes the process of power generation or propulsion via a gas turbine. In many publications in cryogenics, however, the … Continue reading Brayton Cycle

Book Review: Prof. Ralph G. Scurlock’s Stratification, Rollover and Handling of LNG, LPG and Other Cryogenic Liquid Mixtures
This monograph provides comprehensive guides to the often counterintuitive behavior of cryogenic mixtures and to how good practice can minimize the risk of catastrophic events. The theoretical basis for the phenomena described is followed by a full discussion on the practical implications and results, often with real life examples.
Phase Transitions in the Extreme – Gallium Arsenide at 12mK
Researchers from Purdue University have demonstrated a phase transition that crosses two different phase categories, a result never observed before and one that could in time profoundly influence our understanding of matter and phases of matter. The transition from a topologically ordered to a broken symmetry phase was unexpected, and came while the scientists were studying gallium arsenide under both extreme pressure and at temperatures reaching 12mK.
Bulk Storage and Shipping of Liquid Hydrogen is Hazardous
Hydrogen is very attractive as a green fuel because it burns in air to produce only water—and possibly some nitrogen oxides and hydrides—and therefore has a zero carbon footprint. As an energy store and fuel, liquid hydrogen has a high ratio of combustion energy per unit weight and is particularly useful as a space rocket fuel with minimum weight penalty. However, its liquid density is very low and the ratio of combustion energy per unit volume of liquid is about half that of other fuels such as LNG, LPG and other hydrocarbons. The consequences of this fact will create a problem when doubling of the volume for bulk storage and transport is compared with the volume of other fuels.
Breakthrough Initiatives Announces Starshot, Its Light-Sail Starship of Tomorrow
Renowned cosmologist Stephen Hawking and other distinguished researchers joined internet investor and science philanthropist Yuri Milner at One World Observatory to announce a new Breakthrough Initiatives project focused on space exploration and the search for life in the Universe. Called Starshot, the $100 million research and engineering program aims to demonstrate proof of concept for light-propelled nanocrafts. Such starships could fly at 20 percent of light speed and capture images of possible planets and other scientific data in our nearest star system, Alpha Centauri, just over 20 years after launch. The program will be led by Pete Worden, the former director of NASA Ames Research Center, and advised by a committee of world-class scientists and engineers.
Researchers Trigger Long-Distance Phase Transitions
A team of researchers at the Institute for Quantum Electronics at ETH Zurich has shown that particles can be made to "feel" each other even over large distances, resulting in the observation of novel phase transitions that result from energetic three-way battles.
Cryogenic Storage Suggested for Pharmaceuticals in Space
NASA's Human Research Program (HRP) has released a new report that suggests storing pharmaceuticals at cryogenic temperatures on deep space missions, including proposed expeditions to Mars. At issue is both prolonged exposure to radiation and mission lengths that extend well beyond a product's shelf life.
New Magnetism Research Brings High-Temp Superconductivity Applications Closer
A research team led by the US Department of Energy's (DOE's) Argonne National Laboratory (CSA CSM) has discovered that only half the atoms in some iron-based superconductors are magnetic, providing a conclusive demonstration of the wave-like properties of metallic magnetism in these materials. The discovery allows for a clearer understanding of the magnetism in some compounds of iron (the iron arsenides) and how this magnetism helps induce superconductivity, the resistance-free flow of electrical current through a solid-state material that occurs at temperatures up to 138K, or -135°C.
Deposition Technique Results in Copper Oxide Cuprate Superconductivity
Scientists from the US Department of Energy's (DOE) Brookhaven National Laboratory have synthesized ultrathin films containing multiple samples of a copper oxide cuprate in order to study its electronic behavior at near absolute zero. As with other cuprates, the compound is an insulator in its native state and does not readily conduct electricity. Cuprates can become superconducting, however, when chemically doped with strontium atoms, producing (in this case) free-moving electrons in the compound that pair up in the crystalline copper oxide layers where superconductivity is known to occur.
Physicists Discover Flaws in Bean’s Superconductor Theory
University of Houston physicists report finding major theoretical flaws in the "Bean" or "Critical State Model," a generally accepted theoretical explanation of how a superconductor traps and holds a magnetic field. The team's research, published in the Journal of Applied Physics, reveals unexpected new behaviors favorable to practical applications, including the development of energy-efficient ore separators, non-contact magnetic gears that will not wear or require repair, red blood separators with improved yield or even an automated docking system for spacecraft.
