Understanding the physical nature of the electron pairs that define superconductors is one of the most important problems in condensed matter physics, Lebed said. ❋ Unknown (2006)
His experiment gave very direct evidence of the existence of the so-called energy gap in superconductors, which was one of the most important predictions of the theory of superconductivity developed by Bardeen, Cooper and Schrieffer (awarded the Nobel Prize in 1972). ❋ Unknown (1973)
In 1962 this led to the prediction of completely new phenomena in superconductors and in particular to the effects generally known as the Josephson effects. ❋ Unknown (1973)
The experiments showed that his conjecture was correct and his tunnelling method soon became the dominating method to study the energy gap in superconductors. ❋ Unknown (1992)
Last week, in the journal Nature, researchers led by Arthur Hebard of AT&T Bell Labs reported that when bucky balls are spiked with potassium, they carry electricity with no resistance, even at temperatures above where most such "superconductors" work. ❋ Unknown (2008)
But under special circumstances, quantum theory predicts exotic states of matter, such as superconductors in which electrons flow with no resistance and Bose-Einstein condensates in which atoms move as a collective whole. ❋ Unknown (2006)
These "superconductors" had to be very cold, and it took physicists nearly 50 years to come up with an explanation for them: The electron-electron repulsion in these low-temperature superconductors was so weak that with the mediation of lattice vibrations, electrons overcame it, paired up and glided freely without the bumping and heating. ❋ Unknown (2010)
The course, titled "Nanoscience - Physics and Chemistry of Advanced Materials", is jointly run by the Schools of Chemistry and Physics, will offer students a deep understanding of the science of advanced materials, such as superconductors, polymers and lasers found in emerging technologies that underpin nanoscience in total. ❋ Unknown (2010)
Moreover, Smart Grids will utilize a variety of new materials, such as superconductors, carbon nanotubes, and gallium nitride. ❋ MMD Newswire (2010)
Ratner explains that, during the twentieth century, scientists became increasingly sophisticated at studying quantum effects and examining matter at an ever-smaller scale -- leading to the discovery of key materials such as superconductors and carbon nanotubes. ❋ Unknown (2009)
This allows them to be 'superconductors' through which electricity can flow without resistance. ❋ Unknown (2009)
Materials with highly ordered crystalline atomic structures have enormous potential for energy-saving devices such as superconductors, which carry current with no energy loss, and high-speed electronics. ❋ Unknown (2009)
For this reason, most attempts at quantum computation employ ultra-low-temperature environments such as superconductors or cold-atom traps. ❋ Unknown (2009)
Solar power may be one of these technologies, and others may be high-temperature superconductors, discovered in the 1980s, but yet to have much economic impact; biotechnology, still mostly helping research rather than therapy; and space travel, still far too expensive to be of any commercial interest. ❋ Matt Ridley (2011)
Of course, energy is Lynne Kiesling's turf, including her recent posts on cars as distributed generation sites, potential superconductors, and the Toyota Prius. ❋ Unknown (2009)
“It is both tremendously efficient in comparison to normal high-tension lines and has the interesting characteristic that it STORES large amounts of energy in both the hydrogen and the electromagnetic field around the superconductors.” ❋ Unknown (2009)
