Zhiwang Wu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11925891
    Abstract: A filter media and methods are provided. The media is stretchable and exhibits a high degree of elongation which thereby extends its surface area during pleating. By extending surface area of media during pleating, the initial differential pressure is lowered as the area of media is stretched while keeping the same efficiency range with a compressed thickness of media on the affected area.

  • Publication number: 20160038864
    Abstract: A composite filter media includes a base sheet incorporating polymer microfibers and nano-fibrillated cellulose in combination with one or more alternative upstream depth filtration layers. Embodiments of the composite filter media employ polymer or fiberglass layers arranged on the upstream face of the base sheet. A lightweight protective spun bond scrim may be applied to the upstream face of the upstream depth filtration material. The depth filtration layer or layers may be laminated to each other and/or the base sheet or co-pleated with the base sheet to form the disclosed composite media. The depth filtration layers are configured to provide a positive density gradient in the direction of fuel flow through the composite media, meaning that the depth filtration media increases in density and decreases in pore size in the direction of fuel flow.

  • Patent number: 8025861
    Abstract: Titanium oxide (usually titanium dioxide) catalyst support particles are doped for electronic conductivity and formed with surface area-enhancing pores for use, for example, in electro-catalyzed electrodes on proton exchange membrane electrodes in hydrogen/oxygen fuel cells. Suitable compounds of titanium and a dopant are dispersed with pore-forming particles in a liquid medium. The compounds are deposited as a precipitate or sol on the pore-forming particles and heated to transform the deposit into crystals of dopant-containing titanium dioxide. If the heating has not decomposed the pore-forming particles, they are chemically removed from the, now pore-enhanced, the titanium dioxide particles.
