Study Advances Quest For Better Superconducting Materials
2014-01-28 11:55:11

Oak Ridge National Laboratory Nearly 30 years after the discovery of high-temperature superconductivity, many questions remain, but an Oak Ridge National Laboratory team is providing insight that could lead to better superconductors. Their work, published in Physical Review Letters, examines the role of chemical dopants, which are essential to creating high-temperature superconductors – materials that conduct electricity without resistance. The role of dopants in superconductors is...

Universal Ripple May Hold Secret To High-temperature Superconductivity
2013-12-20 15:08:38

University of British Columbia UBC researchers have discovered a universal electronic state that controls the behavior of high-temperature superconducting copper-oxide ceramics. The work, published this week in the journal Science, reveals the universal existence of so-called 'charge-density-waves' -- static ripples formed by the self-organization of electrons in the material's normal state. These ripples carry the seeds out of which superconductivity emerges. "Our understanding of...

A measuring device for superconductors breaks world records Weizmann Institute scientists have taken a quantum leap toward understanding the phenomenon known as superconductivity: They have created the world’s smallest SQUID – a device used to measure magnetic fields – which has broken the world record for sensitivity and resolution. Superconductivity is a quantum phenomenon that only occurs when certain materials are cooled to extremely low temperatures. Then, they lose all...

X-rays Reveal Another Feature Of High-temperature Superconductivity

European Synchrotron Radiation Facility Discovery of a giant resonance puts these materials further apart Classical and high-temperature superconductors differ hugely in the value of the critical temperatures at which they lose all electrical resistance. Scientists have now used powerful X-rays to establish another big difference: high-temperature superconductivity cannot be accounted for by the mechanism that leads to conventional superconductivity. As this mechanism called...

Advances in technology for computation and information storage always require to make the systems smaller and faster. The limits of miniaturization are those set by nature: Materials are composed by specific units, the atoms, that cannot be further divided. The question arising is: Can we still codify information at the atomic scale? And the answer is yes, we can! but one needs to manipulate a property of the atoms, individually, and keep them in that state there for sufficiently long time to...

Study Reveals Origins Of An Exotic Phase Of Matter
2013-11-19 06:34:34

Lawrence Berkeley National Laboratory Understanding superconductivity – whereby certain materials can conduct electricity without any loss of energy – has proved to be one of the most persistent problems in modern physics. Scientists have struggled for decades to develop a cohesive theory of superconductivity, largely spurred by the game-changing prospect of creating a superconductor that works at room temperature, but it has proved to be a tremendous tangle of complex physics. Now...

Crystal could improve performance of electronic devices Quite by accident, Washington State University researchers have achieved a 400-fold increase in the electrical conductivity of a crystal simply by exposing it to light. The effect, which lasted for days after the light was turned off, could dramatically improve the performance of devices like computer chips. WSU doctoral student Marianne Tarun chanced upon the discovery when she noticed that the conductivity of some strontium...

Grand Unified Theory Of Exotic Superconductivity?

Brookhaven National Laboratory Scientists introduce a general theoretical approach that describes all known forms of high-temperature superconductivity and their "intertwined" phases Years of experiments on various types of high-temperature (high-Tc) superconductors—materials that offer hope for energy-saving applications such as zero-loss electrical power lines—have turned up an amazing array of complex behaviors among the electrons that in some instances pair up to carry current...

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...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
