Download or read book New Research on YBCO Superconductors written by David M. Friedman and published by Nova Publishers. This book was released on 2008 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superconductivity is the ability of certain materials to conduct electrical current with no resistance and extremely low losses. High temperature superconductors, such as La2-xSrxCuOx (Tc=40K) and YBa2Cu3O7-x (Tc=90K), were discovered in 1987 and have been actively studied since. In spite of an intense world-wide research, a complete understanding of the copper oxide (cuprate) materials is still lacking. Many fundamental questions are unanswered, particularly the mechanism by which high-Tc superconductivity occurs. More broadly, the cuprates are in a class of solids with strong electron-electron interactions. An understanding of such 'strongly correlated' solids is perhaps the major unsolved problem of condensed matter physics with over ten thousand researchers working on this topic. High-Tc superconductors also have significant potential for applications in technologies ranging from electric power generation and transmission to digital electronics. This ability to carry large amounts of current can be applied to electric power devices such as motors and generators, and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the amount of electricity of ordinary copper or aluminium wires of the same size. This Publication presents new research on yttrium barium copper oxide superconductors, often abbreviated YBCO, which is a chemical compound with the formula YBa2Cu3O7. This material, a famous 'high-temperature superconductor', achieved prominence because it was the first material to superconduct above the boiling point of nitrogen. All materials developed before YBCO became superconducting only at temperatures near the boiling points of liquid helium or liquid hydrogen (Tb = 20.1 K). The significance of the discovery of YBCO is the breakthrough in the refrigerant used to cool the material to below the critical temperature.

Download or read book Superconductivity Research Developments written by James R. Tobin and published by Nova Publishers. This book was released on 2008 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superconductivity is a phenomenon occurring in certain materials at extremely low temperatures, characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field (the Meissner effect). The electrical resistivity of a metallic conductor decreases gradually as the temperature is lowered. However, in ordinary conductors such as copper and silver, impurities and other defects impose a lower limit. Even near absolute zero a real sample of copper shows a non-zero resistance. The resistance of a superconductor, on the other hand, drops abruptly to zero when the material is cooled below its "critical temperature", typically 20 kelvin or less. An electrical current flowing in a loop of superconducting wire can persist indefinitely with no power source. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical phenomenon. It cannot be understood simply as the idealisation of "perfect conductivity" in classical physics. Superconductivity occurs in a wide variety of materials, including simple elements like tin and aluminium, various metallic alloys and some heavily-doped semiconductors. Superconductivity does not occur in noble metals like gold and silver, nor in most ferromagnetic metals. In 1986 the discovery of a family of cuprate-perovskite ceramic materials known as high-temperature superconductors, with critical temperatures in excess of 90 kelvin, spurred renewed interest and research in superconductivity for several reasons. As a topic of pure research, these materials represented a new phenomenon not explained by the current theory. And, because the superconducting state persists up to more manageable temperatures, more commercial applications are feasible, especially if materials with even higher critical temperatures could be discovered. This new book presents leading research from around the world in this dynamic field.
Download or read book Applied Superconductivity 2003 written by Antonello Andreone and published by CRC Press. This book was released on 2004-09-30 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to its tradition, the EUCAS Conference focused on the role of superconductivity in bridging various aspects of research with a variety of concrete advanced applications. The wide interactions among scientists operating worldwide in the field of superconductivity and the sharing of their knowledge and experience represented the main result of the event. The EUCAS Conference has been an ideal forum for presentation and discussion of recent developments in the field of applied superconductivity in the area of power and electronic applications. Great emphasis has been given to materials research directly connected to such applications. For this conference, 515 plenary, invited, and contributed papers were accepted, covering different areas of applications that strongly benefit from the use of superconductivity, such as energy transportation, large magnet systems, biomedical instrumentation, digital electronics, wireless communications, and quantum computing. Forty-two plenary and invited papers are included in Applied Superconductivity 2003, along with a CD-ROM that contains PDF files of all the contributed papers linked from contents lists (and, for completeness, plenary and invited papers). These proceedings are addressed to international physicists, electrotechnical and electronic engineers, material scientists, and chemists interested in the most recent and exciting advances in the field of applied superconductivity.
Download or read book Chemical Solution Deposition of Functional Oxide Thin Films written by Theodor Schneller and published by Springer Science & Business Media. This book was released on 2014-01-24 with total page 801 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first text to cover all aspects of solution processed functional oxide thin-films. Chemical Solution Deposition (CSD) comprises all solution based thin- film deposition techniques, which involve chemical reactions of precursors during the formation of the oxide films, i. e. sol-gel type routes, metallo-organic decomposition routes, hybrid routes, etc. While the development of sol-gel type processes for optical coatings on glass by silicon dioxide and titanium dioxide dates from the mid-20th century, the first CSD derived electronic oxide thin films, such as lead zirconate titanate, were prepared in the 1980’s. Since then CSD has emerged as a highly flexible and cost-effective technique for the fabrication of a very wide variety of functional oxide thin films. Application areas include, for example, integrated dielectric capacitors, ferroelectric random access memories, pyroelectric infrared detectors, piezoelectric micro-electromechanical systems, antireflective coatings, optical filters, conducting-, transparent conducting-, and superconducting layers, luminescent coatings, gas sensors, thin film solid-oxide fuel cells, and photoelectrocatalytic solar cells. In the appendix detailed “cooking recipes” for selected material systems are offered.

Download or read book The Paradox of Skills written by Linda Anne Barkas and published by Springer Science & Business Media. This book was released on 2011-11-13 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives underpinning the policies to expand and widen participation have impacted on university provision to help students improve their general literacy and academic writing skills. This book examines how and why Students’ Skills Centres, (SSCs), gained such a hold in the sector, despite the contentious nature of the research evidence that challenges the notion of the applicability of generic writing skills. It is argued in the book, that on a small scale, SSCs illustrate the paradoxes and ironies that have developed in higher education. ‘
