A three-car version of the Superconducting Magnetically Levitated (MagLev) train achieved the world record of 581 km/h (361 mph) for a rail vehicle in December 2003, a record that still stands today. The vehicle relies on superconducting magnets and linear motor technology, which rule out the frictional forces genera... |

Previously, scientists believed that the superconductive properties of a particular substance were homogeneous in all directions, but the latest study at the Brookhaven Laboratory has proven to be anything but that. In fact, two-dimensional fluctuating superconductivity in a high-temperature superconductor is determi... |

Certain metals can be determined to act as superconductors, when cooled to temperatures close to absolute zero, or 0 K. The effect was discovered at the beginning of the 20th century, when a Dutch physicist by the name of Kamerlingh Onnes designed an experiment to observe how certain materials behave at low temperatu... |

Everybody knows refrigerators are indispensable household appliances that transfer heat from inside it to the external environment, cooling the contents to a temperature below ambient. But while commercial refrigerators get bigger to fit more food and drinks, a group of scientists worked on developing the smallest o... |

The first pictures of the spatial distribution of a magnetic field penetrating a superconductor were presented by a team of researchers at the U.S. Department of Energy's Ames Laboratory. They show strange two-dimensional equilibrium patterns and intricate models.Soap-foam like structures display on the surface... |

Soon, electric aircrafts could be flying in the skies and they could be built using the most advanced electric systems, thanks to superconductors. These projects may still be on the drawing boards for now, but the fact is they could be far more efficient than conventional aircraft, produce less greenhouse emissions ... |

Superconductivity is a phenomenon occurring in certain materials at extremely low temperatures, characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field. They are thought to appear usually below -140 degrees Celsius. Superconductors are used in many applications, like MRI ... |

Many people have heard about the phrase "absolute zero," not many know what it really implies, and fewer have asked themselves the question "what happens below absolute zero?" Are there upper and lower limits to temperature?Absolute zero is known to be 0 K (-273.15 °C, -459.67 °F) and it's used to describe a th... |

Superconductors are a class of materials that display exactly zero electrical resistance and the exclusion of the interior magnetic field (the Meissner effect) at extremely low temperatures, usually below -140 degrees Celsius. They are used in many applications, like MRI medical imaging scanners, levitating trains a... |

The design of the electric motor, which converts electrical energy into mechanical energy, hasn't changed much since it was invented, some 50 years ago. New technological developments in the field of superconductors are about to change that.El Hadj Ailam and colleagues working at the Université Henri Poincaré i... |

A group of researchers have recently announced the creation of a completely new state of matter that combines the characteristics of lasers with those of the world's best electrical conductors. They successfully demonstrated the existence of the phase, besides the previously known ones: solids, liquids, gases, ... |

20 years ago, researchers at the Argonne National Laboratory came with the most known high-temperature superconductor YBa2Cu3O7. Now, they have solved another puzzle of the superconductivity: how a slight change in the structure of electron-doped superconductors turns superconductivity on and off. Superconductivity i... |
