A unified electrostatic and cavitation model for first-principles molecular dynamics in solution.
The electrostatic continuum solvent model developed by [Fattebert and Gygi J. Comput. Chem. 23, 662 (2002); Int. J. Quantum Chem. 93, 139 (2003)] is combined with a first-principles formulation of the cavitation energy based on a natural quantum-mechanical definition for the surface of a solute. Despite its simplicity, the cavitation contribution calculated by this approach is found to be in re...
متن کاملFirst Principles Molecular Dynamics Simulation of Solution
We summarize the preliminary results concerning the hydration structure of trivalent rare-earth ions and the charge localization process in DNA fibers obtained during this fiscal year using a first principles molecular dynamics approach. In the first case, we demonstrated that the free energy surface obtained using the metadynamics based on the Car-Parrinello molecular dynamics for the hydratio...
متن کاملpassivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Structure of a uranyl peroxo complex in aqueous solution from first-principles molecular dynamics simulations.
Static ab initio and density-functional computations, as well as Car-Parrinello molecular dynamics simulations in aqueous solution are reported for [UO2(OH)(κ(2)-O2)(H2O)2](-) and [UO2(OH)2(κ(1)-O2H)(H2O)](-). Whereas the κ(1)-hydroperoxo isomer is found to be more stable than the κ(2)-peroxo form in the gas phase, the order of stability is reversed in explicit bulk solution. Based on free ener...
متن کاملVibrational spectra of phosphate ions in aqueous solution probed by first-principles molecular dynamics.
We have carried out "first-principles" Born-Oppenheimer molecular dynamics (BOMD) simulations of the phosphate ions H₂PO₄⁻ and HPO₄²⁻ in liquid water and have calculated their IR spectra by Fourier transform techniques from the trajectories. IR bands were assigned by a so-called "generalized normal coordinate analysis". The effects of including Hartree-Fock (HF) exchange into the density functi...
