Latest Superconductivity Stories
Findings may lead to precision engineering of superconducting thin films for electronic devices.
In finally answering an elusive scientific question, researchers with the U.S. Department of Energyâ€™s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the selective placement of strain can alter the electronic phase and its spatial arrangement in correlated electron materials.
The US Department of Energy's (DOE's) Thomas Jefferson National Accelerator Facility marked a step forward in the field of advanced particle accelerator technology with the successful test of the first US-built superconducting radiofrequency (SRF) niobium cavity to meet the exacting specifications of the proposed International Linear Collider (ILC).
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.
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...
