Rate and mechanisms for water exchange around Li (super +) (aq) from MD simulations

Article Abstract:

The solvent exchange rate of aqueous Li (super+) was determined by employing the reactive flux method in combination with very long molecular dynamics simulations based on effective three-body ion-water potentials. The mechanisms for the resulting exchange events were studied in considerable details and analyzed in terms of the five commonly discussed exchange classes, associative (A), dissociative (D), and interchange (I, I (sub a), I (sub d).

Influence of substrate dynamics on CO-MgO(001) bonding-using molecular dynamics snapshots in quantum-chemical calculations

Article Abstract:

The classical molecular dynamics (MD) and quantum mechanics (QM) embedded-cluster calculations are combined to investigate the adsorption of CO on a dynamically distorted MgO(001) surface. The distribution of adsorption energies for CO above the Mg(super 2+) sites on the MgO(001) surface at 50, 80, and 150 K is predicted by using the linear expression.
