Latest Superconductivity Stories
Scientists at NASA's Jet Propulsion Laboratory have now successfully used magnetic fields to levitate mice.
Canadian scientists are challenging physics' single-band Hubbard theory that's used to predict and calculate behavior of high-temperature superconductors. University of British Columbia researchers said their findings mark the first compelling evidence challenging the Hubbard model under certain conditions, and could necessitate entirely new theoretical approaches to explaining superconductivity in certain materials. Single-band Hubbard physics has been used for 20 years to predict how...
New UBC research has literally and figuratively poked holes in single-band Hubbard physics--a model that has been used to predict and calculate the behavior of high-temperature superconductors for 20 years.
Hydrogen, the most common element in the universe, is normally an insulating gas, but at high pressures it may turn into a superconductor.
Reports about swimmers menaced by giant squids off San Diego raised the ire of marine biologist Brad Seibel who found the awesome monsters are really timid. And, afraid of the light. I want to spread the word that they aren't the aggressive man-eaters as they have been portrayed, said Seibel who has taken moonlight swims surrounded by a big gang of squids. For years Seibel, a biologist at the University of Rhode Island, had heard stories claiming that a Humboldt squid will devour a dog in...
Superconductivity appears to rely on very different mechanisms in two varieties of iron-based superconductors.
Superconductivity is a unique state in which electrons move freely inside a solid material. This complete lack of electrical resistance could translate to incredibly efficient electric power cables, as well as many other promising technologies.
Researchers at the National Institute of Standards and Technology (NIST) have discovered that a reduction in mechanical strain at the boundaries of crystal grains can significantly improve the performance of high-temperature superconductors (HTS).
University of Texas at Austin physicists have created a superconducting lead sheet only two atoms thick, the thinnest such metal layer ever created. Professor Ken Shih and colleagues said the achievement lays the groundwork for future superconductor technologies. To be able to control this material -- to shape it into new geometries -- and explore what happens is very exciting, Shih said.
A superconducting sheet of lead only two atoms thick, the thinnest superconducting metal layer ever created, has been developed by physicists at The University of Texas at Austin.
An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
