  • Medical Device Link . The use of microporous polymer membranes in immunoassays
    of rapid immunoassays using these high-surface-area materials has proliferated. Initially much investigation centered on understanding the interactions between proteins and polymers and the requirements for blocking nonspecific interactions on the membrane, and on developing a series of detection

    ) irradiation. A third strategy involves suppressing the expansion of the polymer electrolyte membrane as it absorbs MeOH. An inorganic-organic composite membrane provides a ceramic matrix with connected uniform three-dimensionally ordered pores in the polymer electrolyte membrane to suppress the expansion
  • Filtration Performance of Permanently Hydrophilized Polyethylene Membranes
    Lydall Performance Materials B.V. recently developed an innovative membrane platform based on Ultra High Molecular Weight Polyethylene (UHMwPE), a chemically inert and highly durable polymer. The new generation of UHMwPE membranes include Solupor (R) HF membranes and Arioso (R) high performance air
  • Medical Device Link .
    than a mechanical one. Most filter membranes currently are obtained by means of casting. A porous polymer layer (the membrane) is formed by precipitation of a carefully defined mixture of solvents and polymers. The resulting structure resembles a very thin sponge having extremely small pores
  • A Fuel Cell in Your Phone - By David Voss - p.4 - April 2002 FCT -
    centimeters. His group used microfabrication techniques to "print" five to six layers of fuel cell components the membrane, electrode and catalyst on ceramic and silicon wafers, and more recently on a flexible polymer material. At this scale, he's using hydrogen as a fuel, stored as sodium
  • P.2) Small Fuel Cells 2007 | by George H. Miley | F C T | May 2007 |
    focus at PolyFuel. Hydrocarbon membranes are being engineered to optimize the power density, fuel efficiency and fuel cell operating conditions over a range of system architectures. Membrane production is focusing on hydrocarbon polymer chemistry, roll-to-roll membrane production, catalysis application
  • Pg.2 - Year 2002 Fuel Cell Seminar, Palm Springs, CA - By Donald MacArthur - January 2003 FCT -
    Year 2002 Fuel Cell Seminar What has happened since the last meeting? The industry has moved to the sampling and demonstration phase. The PEMFC (polymer electrolyte or proton exchange membrane fuel cell) developers have perhaps a couple of hundred units in the 500W to 5kW range out in the field
  • U.S. Fuel Cell and Battery Patents - May 2002 FCT -
    U.S. FUEL CELL AND BATTERY PATENTS Compiled by Eddie T. Seo Official Gazette, Volume 1256 (March 2002) U.S. 6,352,742 (20020305), Method for producing polymer electrolyte membrane and fuel cell, Makoto Murata, Tetsu Yamamoto, and Gregor Deckers, Celanese Ventures GmbH (DE).
