    摘要: The present invention is directed to the activation of metal carbonyl clusters by an oxidative agent to prepare a stable metal cluster catalyst exhibiting catalytic rate enhancement. The activation comprises, for example, using oxygen for decarbonylation of carbonyl ligands and changing the oxidation state of the other ligands. In one aspect, treatment of the metal cluster catalyst under oxidative conditions in a flow reactor leads to removal of CO ligands and oxidation of bound calixarene phosphine ligands, and results in a stable activated open metal cluster that is more active for ethylene hydrogenation catalysis. The resulting metal cluster contains coordinatively unsaturated sites comprising carbonyl vacancies. In one aspect, the resulting activated open metal cluster can be used as a catalyst in a variety of chemical transformations.

    摘要: A method using quartz resonators probes dynamically the mechanical characteristics of thin films. This method probes the film properties at the anti-resonance frequency where the vibrational amplitude is smallest, minimizing nonlinear contributions in the dependence of the film mechanical characteristics on the resonator electrical characteristics. Determination of the mechanical characteristics involves impedance analysis, transformation of .vertline.Y.vertline. and .theta. data into a linear form so that the conductance and susceptance at the frequency of minimum absolute admittance can be accurately determined, and use of a two-dimensional Newton-Raphson numerical method to determine the values of the storage modulus G', loss modulus G", as well as various other film and resonator properties.
