Available in PDF, EPUB and Kindle. Book excerpt: We have discovered the first layered superconducting copper oxide with small, fixed oxidation state cations separating the conducting CuO2 planes. This material, GaSr2Y{sub 1-x}Ca(subscript x)Cu2O--, is similar to YBa2Cu3O-- with the square planar copper chains replaced by chains of edge-shared GaO4 tetrahedra. Thus, oxidation can occur only for the copper ion located in square pyramidal coordination in the CuO2 plane. The undoped parent compound, x = 0, does not show magnetic order above 4K, probably due to the presence of the thick, ionic region separating the CuO2 planes. However, this ionic region does not suppress high {Tc} superconductivity ((approximately)70K) for the doped compositions.

Book Synopsis Preparation and Characterization of Isotopic Oxygen-enriched Yttrium Barium Copper Oxide by :
Download or read book Preparation and Characterization of Isotopic Oxygen-enriched Yttrium Barium Copper Oxide written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The preparation of labeled superconducting yttrium barium copper oxides from the labeled metal nitrates is described. The materials were characterized by a variety of physical techniques, and their superconducting properties were measured. Trends are seen in the structural parameters of the materials obtained by the nitrate route and also in isotopically enriched materials prepared via gas-phase exchange. These structural changes are accompanied by changes in superconducting properties. The 18O-enriched yttrium barium copper oxide prepared via the nitrate route has a T/sub c/depressed by 33°K to 59°K, whereas a 17O sample has a T/sub c/ between the 18O material and similarly prepared 16O sample. 15 refs., 1 fig., 3 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: Transition metal oxides are receiving a great deal of attention because the materials produced are showing promise in the fields of catalysis and electrochemistry. These materials are being produced in a variety of ways, but the low temperature hydrothermal method is producing materials with desired structural characteristics. This study discusses efforts in mild reaction conditions of heat temperatures ranging between 160 and 200 deg C. The factors of pH, reaction time, reaction temperature, and the presence of organic templating cations are also studied to see their impact on traditional and microwave reactions. The relatively new field of microwave synthesis has shown that materials which customarily took 2 days of reaction time in the traditional ovens are reproducible in 30-60 minutes via the microwave ovens. The influence of the organic cations in the reaction mediums is the focus of this particular study. The ability to produce layered vanadium oxides in the absence of such templating cations as TMA would make the materials potentially better for electrochemical purposes. This research used a variety of solvents in an attempt to produce interlayer bridging by organic anions. The solvents of ethylene glycol and acetic acid act as those bridges, each with 2 accessible oxygens.
