  • Publication number: 20040063915
    Abstract: Protein polymers coated with a metal are provided. New methods are described for the preparation of tubulin-based microtubules such that they may be coated, by an electroless plating method, with gold particles of <20 nm in diameter without prior reaction with noble metal catalysts. The gold particle deposition can occur in suspension or on microtubules lying on a surface. Gold enhancement of the gold-particle coating and annealing results in ohmic conductance that is within a factor of ten of the resistivity of bulk gold. These methods are likely to be applicable to other protein polymers.

  • Patent number: 6586640
    Abstract: A process for the manufacture of a hydroxy-substituted organic compound comprising decomposing an organic hydroperoxide, preferably a compound of the formula Ar—C(CH3)2O2H, wherein Ar is a substituted or unsubstituted mononuclear or polynuclear aromatic group. The decomposition is carried out in the presence of a catalyst comprising highly fluorinated polymer having sulfonic acid groups with the catalyst being in the form of particles of which at least about 20 weight % have a particle size less than about 300 &mgr;m. Cumene hydroperoxide can be decomposed in the process to phenol and acetone which can be reacted to form bisphenol A in the presence of the same catalyst that was used for the decomposition.
