  • SEMICONDUCTOR NANOPARTICLE/NANOFIBER COMPOSITE ELECTRODES
    Publication number: 20110079275
    Abstract: Composite electrode materials for DSSCs, DSSCs incorporating the composite electrode materials and methods for making the composite electrode materials are provided. The composite electrode materials are composed of semiconductor nanofibers embedded in a matrix of semiconductor nanoparticles. DSSCs incorporating the composite electrode materials exhibit both increased carrier transport and improved light harvesting, particularly at wavelengths of 600 nm or greater (e.g., 600 nm to 800 nm or greater).

  • Polyoxymethylene as structural support member and propellant
    Publication number: 20050034447
    Abstract: A vehicle includes at least one polyoxymethylene structural support member. The polyoxymethylene structural support member includes a polyoxymethylene component that is a propellant that provides thrust to the vehicle upon pyrolysis or combustion of the polyoxymethylene component of the product of pyrolysis of the polyoxymethylene component. The vehicle can be a satellite or other type of spacecraft.
