New Superconducting Materials Improve the Efficiency and Reliability of Grids and Systems For the first time, a superconducting current limiter based on YBCO strip conductors has now been installed at a power plant. At the Boxberg power plant of Vattenfall, the current limiter protects the grid for own consumption that is designed for 12 000 volts and 800 amperes against damage due to short circuits and voltage peaks. The new technology co-developed by Karlsruhe Institute of Technology and...

Study represents step toward unified theory for quantum phase transformation New evidence this week supports a theory developed five years ago at Rice University to explain the electrical properties of several classes of materials -- including unconventional superconductors -- that have long vexed physicists. The findings in this week's issue of Nature Materials uphold a theory first offered in 2006 by physicist Qimiao Si, Rice's Harry C. and Olga K. Wiess Professor of Physics and...

Scientists Mimic Zero Gravity With Magnets

University of Nottingham scientists have been levitating fruit flies with magnets to determine how biological organisms are affected by weightless conditions in space. The team has shown that simulating weightlessness in fruit flies on Earth by using magnets causes the flies to walk more quickly, which is a similar finding astronauts have had in experiments on the International Space Station. “It is unfeasible to apply this technique to investigating the effects of weightlessness...

Researchers from North Carolina State University have developed a new computational approach to improve the utility of superconductive materials for specific design applications — and have used the approach to solve a key research obstacle for the next-generation superconductor material yttrium barium copper oxide (YBCO). A superconductor is a material that can carry electricity without any loss — none of the energy is dissipated as heat, for example. Superconductive materials...

Sophisticated electron-imaging technique reveals widespread "destruction," offering clues to how material works as a superconductor It's a basic technique learned early, maybe even before kindergarten: Pulling things apart - from toy cars to complicated electronic materials - can reveal a lot about how they work. "That's one way physicists study the things that they love; they do it by destroying them," said Séamus Davis, a physicist at the U.S. Department of Energy's (DOE)...

'Electron superhighway' could pave way for creation of elusive quantum-particle pairs Rice University physicists have created a tiny "electron superhighway" that could one day be useful for building a quantum computer, a new type of computer that will use quantum particles in place of the digital transistors found in today's microchips. In a recent paper in Physical Review Letters, Rice physicists Rui-Rui Du and Ivan Knez describe a new method for making a tiny device called a "quantum...

Nobel Prize Winner Leaves Group Over Global Warming

  A Nobel Prize winning physicist has resigned from the American Physical Society (APS), protesting the organization's official stance on climate change, Philip Sherwell of the Telegraph reported on Sunday. Ivar Giaever, an 82-year-old Norwegian who shared the 1973 Nobel Award for work related to quantum tunneling, left the 48,000 member organization earlier this month because of the APA's position arguing that there is a scientific consensus on the global warming issue. The...

A team of Spanish researchers claim to have designed what is being called an antimagnetic cloak -- a cloak that shields objects from external magnetic fields, while keeping internal magnetic fields from escaping. According to a September 22 press release, physicists and engineers from the Universitat Autònoma de Barcelona (UAB) designed the cloak, which they said can be created "using practical and available materials and technologies." Richard Chirgwin of The Register...

Spanish researchers have designed what they believe to be a new type of magnetic cloak, which shields objects from external magnetic fields, while at the same time preventing any magnetic internal fields from leaking outside, making the cloak undetectable. The development of such a device, described as an 'antimagnet', could offer many beneficial applications, such as protecting a ship's hull from mines designed to detonate when a magnetic field is detected, or allowing patients with...

  Tel Aviv University researchers marry old and new to create the next generation of superconductors Wiring systems powered by highly-efficient superconductors have long been a dream of science, but researchers have faced such practical challenges such as finding pliable and cost-effective materials. Now researchers at Tel Aviv University have found a way to make an old idea new with the next generation of superconductors. Dr. Boaz Almog and Mishael Azoulay working in the group...

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...

Word of the Day
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
