    摘要: The durability of a PEM fuel cell is improved by replacing carbon catalyst support materials in the cathode (and optionally both electrodes) with a titanium oxide support. The electrode thus preferably contains noble metal containing catalyst particles carried on catalyst support particles of titanium oxide. The catalyst-bearing titanium oxide particles are mixed with electrically conductive material such as carbon particles. The combination of platinum particles deposited on titanium dioxide support particles and mixed with conductive carbon particles provides an electrode with good oxygen reduction capacity and corrosion resistance in an acid environment.

    摘要: Mail processing systems and methods. A method includes scanning a plurality of mail pieces in a first processing step to produce mail piece images. The method includes producing a template based on a plurality of the mail piece images and associating a plurality of mail pieces with the template, the associated plurality of mail pieces forming a mail set. The method includes identifying quality-control problems associated with the mail set, separating the mail set from other mail during a second processing step, and separately processing the mail set from the other mail.

    摘要: Nanometer sized particles containing titanium and platinum are prepared by a sonochemical process. Compounds of the metals are dissolved, suspended, or diluted in a low vapor pressure liquid medium, preferably at a sub-ambient temperature. A reducing gas is bubbled through the liquid as it is subjected to cavitation to affect the reductive decomposition of the metal compounds. Titanium and platinum are co-precipitated in very small particles.
