    Chemoconvection: A chemically driven hydrodynamic instability

    Abstract: We describe theory and experiments concerning a chemical reaction, the alkaline oxidation of glucose with methylene blue as a catalyst, that is hypothesized to drive fluid motion via an overturning instability, as an example of a “chemoconvective” process. A theoretical model is developed to explain this phenomenon and linear analyses from steady and pseudosteady states are used to predict the basic length and time scales of the patterns which initially appear. These theoretical predictions, using kinetic parameters from recent independent experiments, are contrasted with results from pattern initiation experiments. Preliminary comparisons indicate good qualitative and quantitative agreement.

    Quantum chemistry calculation of excited three center systems: Theoretical study of He2++H2 collisions
    AIP Publishing ; 2003

    In: The Journal of Chemical Physics, AIP Publishing, Vol. 119, No. 1 ( 2003-07-01), p. 325-337
    Abstract: Close-coupling calculations of single (dissociative and nondissociative) and double electron capture cross sections in He2++H2 collisions in the range of impact energies 0.5–25 keV/amu are presented and compared with experimental data. The calculations have been carried out at the Franck–Condon level and employing both ab initio expansions, in terms of three-center electronic functions, and the independent particle model approximation. We discuss the mechanisms of the processes and the validity limits of these treatments.
