Abstract: A hub for off-road motorcycle includes a bearing having a first portion and a second portion respectively formed on two opposite ends thereof. Each of the first portion and the second portion has a connecting flange extended therefrom. A first annular element has a first through hole defined therein. The first annular element has a plurality of first spoke holes defined therein. A second annular element has a second through hole defined therein. The second annular element has a plurality of second spoke holes defined therein. When the hub adapts to be assembled with spokes, the first annular element and the second annular element are slightly pivotally rotated relative to the bearing for adapting to easily adjustably assemble the spokes with a rim.

Abstract: Porous ceramic superconductors having a film thickness over 0.5 microns are provided. The superconducting material is applied to a vicinal substrate and optionally nanoparticles are inserted to release local strain. The resultant superconductors exhibit improved Jc values compared to nonvicinal (flat) counterparts and those having no nanoparticles.

Abstract: The present invention relates to a method and product resulting from application distortion security images in an anti-copy document, printed on demand, which may be variable and use laser printers or printer/copiers and/or ink-jet printers and/or digital presses.

Abstract: Improved Hg-containing superconducting films and thermoelectric materials are provided. The films are fabricated by annealing starting T1-containing films (e.g., T1-1212 or T1-2212) in an Hg-vapor environment so as to cause a substitution of T1 by Hg without substantial alteration of the crystalline structure of the starting films. Preferably, a body comprising a substrate having an epitaxial T1-containing film thereon is annealed under vacuum conditions with a Hg-based bulk; typical annealing conditions are 600-900° C. for a period of from about 1-20 hours. The final Hg-containing film products have a Jc of at least about 106 A/cm2 (100 K, OT) and a Xmin of up to about 50%. The thermoelectric materials are prepared by perturbing a crystalline precursor having a structure similar to the final material so as to cause a first molecule to be released from the precursor.
