Preparation of Superconducting YBa2Cu3O7−δ Thin Films by the Dipping-Pyrolysis Process Using Organic Acid Salts
Authors: Kumagai Toshiya , Yokota Hiroshi , Kawaguchi Kenji , Kondo Wakichi , Mizuta Susumu 
Published: July 2006

Abstract
Thin films of the superconductor YBa2Cu3O7−δ (YBCO) were prepared on yttria stabilized zirconia (YSZ) substrates by the dipping-pyrolysis process. The starting solution, produced by dissolving barium and copper naphthenates and yttrium stearate into an organic solvent, was coated on the substrates and heated up to 800 °C. Resistivities of the films were measured by the four probe method and superconduction was observed at Tc = 90 K (onset) and 60 K (end).
Improvement of Mechanical Properties of Metaphosphate Glass by Addition of Chromium Oxide
Authors: Yoshimoto Mamoru , Soga Naohiro 
Published: July 2006

Abstract
The mixed alkaline earth metaphosphate glasses containing various amounts of Cr2O3 were prepared, and their mechanical properties were measured. With the addition of Cr2O3, Young’s modulus was improved from 60 to 120 GPa, Vickers hardness from 4 to 8 GPa, and toughness from 0.6 to 1.1 MPa m1⁄2. This improvement was attributed to the change of glass structure from the linear chain and/or ring structure of metaphosphate glass to the three dimensional structure.

Enhanced Stabilization Reactivity of Coal Tar Based Mesophase Pitch Fiber by Blending PVC Pitch
Authors: Mochida Isao , Toshima Hiroshi , Korai Yozo , Matsumoto Tadayuki 
Published: July 2006

Abstract
PVC pitch prepared at 420 °C for 2 h was blended into a coal tar based mesophase pitch to enhance the stabilization reactivity of the whole pitch fibers. No deterioration of spinnability was recognized after the blending, suggesting their high compatibility. The oxidative stabilization in the air at 270 °C took 120 min for the stabilization of the parent mesophase pitch fibers to maintain its fiber form during the carbonization up to 600 °C, while the pitch fibers from the blends with PVC pitch in 5 or 10 wt% took 80 min to be stabilized. Blended PVC pitch is supposed to be oxidized more easily to react with coal tar derived molecules, enhancing the stabilization reactivity of the whole fiber.
