Wong Alessandra Lanzara is a Berkeley professor of physics and a member of Lawrence Berkeley National Laboratory's Materials Sciences Division. Photo credit: courtesy Alessandra Lanzara Imagine a world where electricity was virtually free and the means to store it limitless. Alessandra Lanzara, a Berkeley professor of physics, sees a way to reach this goal: by restringing the power grid with high temperature superconductors. "There is a lot of waste getting electricity from its production site to your home. This is because materials that carry a current have resistivity; their conduction isn't perfect," Lanzara says. Superconductors, on the other hand, can transmit a current without loss when chilled below a critical temperature. Power lines made of superconductors, Lanzara argues, could retain the energy now lost to waste, drastically increasing the amount available for use and decreasing its cost. Superconductors can also hold a current indefinitely without any loss of power, making them ideal for storing intermittent energy from sources like the sun.

But in the 1970s, scientists discovered that impurities added to certain polymers made it possible for them to carry small electrical currents. Now, researchers at Lucent Technologies' Bell Labs have gone a step further. By "tricking" a common polymer, they've found a way to make plastic conduct electricity with no resistance at very low temperatures. The Bell Labs development caps 20 years of research aimed at creating the first organic superconductor. "A new window into nature has opened up," asserts Ananth Dodabalapur, a device physicist at Bell Labs and member of the research team. The polymer, called polythiophene, is used in making inexpensive optical devices such as display panels and "smart" pixels. But its potential as a superconductor may be far greater. The research, which was reported on Mar. 8 in the journal Nature , may be a harbinger of other superconducting polymers that could be used to create superfast "quantum" computers and other superconducting electronic devices.

Applied superconductivity and magnet development Superconductors - high and low temperature Magnetism and superconductivity A T Boothroyd In recent years increasing evidence has been found for a link between the physics of magnetic ordering and certain types of superconductivity. We aim to investigate this link through fundamental studies on simple model compounds exhibiting novel magnetic and superconducting behaviour. Much of the work is motivated by the desire to understand the mechanism of superconductivity in unconventional systems, such as the layered cuprate high-Tc superconductors. Current problems of interest include: i) magnetic structures and spin fluctuations in cuprate high-Tc superconductors and related, low dimensional quantum magnets ii) orbital fluctuations in rare earth and transition metal systems iii) charge and spin ordering in doped antiferromagnets iv) novel methods of data analysis and visualisation.

51. The Quest For A New Class Of Superconductors Dec 20, 2007 Fifty years after the Nobelprize winning explanation of how superconductors work, a research team from Los Alamos National Laboratory, http://www.eurekalert.org/pub_releases/2007-12/danl-tqf122007.php

Public release date: 20-Dec-2007 E-mail Article Contact: James E. Rickman jamesr@lanl.gov DOE/Los Alamos National Laboratory The quest for a new class of superconductors Possibilities abound 50 years after theory of superconductivity LOS ALAMOS, New Mexico, December 20, 2007—Fifty years after the Nobel-prize winning explanation of how superconductors work, a research team from Los Alamos National Laboratory, the University of Edinburgh and Cambridge University are suggesting another mechanism for the still-mysterious phenomenon. In a review published today in Nature, researchers David Pines, Philippe Monthoux and Gilbert Lonzarich posit that superconductivity in certain materials can be achieved absent the interaction of electrons with vibrational motion of a material’s structure. The review, “Superconductivity without phonons,” explores how materials, under certain conditions, can become superconductors in a non-traditional way. Superconductivity is a phenomenon by which materials conduct electricity without resistance, usually at extremely cold temperatures around minus 424 degrees Fahrenheit (minus 253 degrees Celsius)—the fantastically frigid point at which hydrogen becomes a liquid. Superconductivity was first discovered in 1911. A newer class of materials that become superconductors at temperatures closer to the temperature of liquid nitrogen—minus 321 degrees Fahrenheit (minus 196 degrees Celsius)—are known as “high-temperature superconductors.”

skip to main skip to sidebar liveatthewitchtrials Sunday, March 09, 2008 Useful Superconductors FX prediction market has a bet on the likelihood of an alloy high-Tc superconductor by 2017. The current market value of this places it at 65% likely. 77 kelvin is given as the useful figure because this is the boiling point of Nitrogen. Liquid nitrogen is in fairly cheap plentiful supply so if you can get a superconductor that works at that temperature it is useful for commercial applications. Being malleable and ductile would also add to the practical applications of the superconductor. Malleable and ductile in this description are slightly ambiguous, I assume only metallic compounds can have these qualities but I could be wrong. So replace malleable and ductile with metallic in the post if that is a better description. Superconductors have all sorts of known useful applications . It is such a weird property that trying to figure out what you can do with them is like a bronze age swordmaker trying to figure out all applications of iron. This is an in depth description of the superconductivity phenomenon. Figure 12 shows the historical evolution of the maximum superconducting temperature.

The primary problem with the current use of electricity is that of electrical resistance. In broad terms, this refers to the "opposition" of the materials to the electricity passing through them. Almost all materials now used to conduct electricity exhibit resistance to some degree or another. This results in some loss in the electrical power distributed to consumers and users - either in terms of generating heat (which is the reason for cooling fans and "heat sinks" in many electrical appliances - they are needed to dissipate the heat created by electrical resistance) or an outright drop in power throughput - resulting in a very inefficient use of the power generated. An answer to the problem lies in the development of superconductors - materials in which electrical resistance is zero, which will result in full use of every volt of electricity generated.

Illuminating a Second 'Kink' in High-Tc Superconductors “Big kink” (left) vs. “small kink” (right). a) OP91 BSCCO (T=10K). b) Brillouin zone (BZ) and Fermi surface (FS) for BSCCO (solid line) and LBCO (dashed line). Straight lines represent the momentum lines probed in the spectra with correspondingly colored dispersion. c) and d) LBCO spectra at x=0.125 for two different momentum lines as indicated in b). e) ARPES intensity from the nodal line in superconducting state in optimally doped BSCCO. The velocity or rate of dispersion changes in the vicinity of the Fermi level, resulting in a “kink” in dispersion at ~60 meV bellow the Fermi level. “Small kink” image from “Evidence for Quantum Critical Behavior in the Optimally Doped Cuprate Bi2Sr2CaCu2O8+d,” T. Valla, A. V. Fedorov, P. D. Johnson, B. O. Wells, Q. Li, G. D. Gu, and N. Koshizuka, Science 285, 2110 (1999). There’s another kink in the mystery of high-temperature (Tc) superconductors – literally. Using photoemission studies at the NSLS, a group of researchers has revealed a new anomaly, or “kink,” in the energy spectrum of high-energy electrons in two different families of cuprate superconductors, further complicating their quest to discover exactly how the materials conduct electricity with zero resistance.
