  • Patent number: 8248681
    Abstract: The present disclosure relates generally to polyaniline (PANI) materials capable of undergoing stable and reversible polyelectrochromic transitions between multiple oxidation states. More specifically, the embodiments described herein include novel PANI-PAAMPSA structures that are capable of undergoing stable and reversible transitions between the ES, LB and PB oxidation states. In some embodiments, the structures described are capable of undergoing stable transitions over a broad pH range. Also described herein are methods of preparing certain electrochromic structures.

  • Patent number: 8247443
    Abstract: A novel small molecule antagonizes two types of acyl homoserine lactone receptors: membrane-bound and cytoplasmic. A focused library of analogs and derivatives of the original antagonist was synthesized. Analog and derivative molecules harbor a range of activities. The novel small molecule and most potent antagonist protects the eukaryote Caenorhabditis elegans from quorum-sensing-mediated killing by the bacterial pathogen Chromobacterium violaceum. The saving of C. elegans demonstrates the use of these molecules as small molecule antimicrobials.

  • Patent number: 8093098
    Abstract: A method for enhancing electrical conductivity of a film which includes at least one conductive polymer. The method includes providing the film comprising the at least one conductive polymer and at least one polymer acid, agitating the film in at least one reagent; and, placing the film on a heated surface. The at least one reagent includes a reagent acid that is stronger than the polymer acid. The conductivity of the treated film is significantly greater than the conductivity of the untreated film.
