Multiscale modeling framework for nanoparticles, nanomaterials and nanotechnology

M

olecular theory of solvation for nanostructures in both aqueous and non-aqueous solution, a.k.a. three-dimensional

reference interaction site model (3D-RISM) with Kovalenko-Hirata (KH) closure relation, was systematically

developed and applied to a variety of compounds, supramolecules and biomolecules in a number of solvents, mixtures,

electrolyte and non-electrolyte solutions. From the first principles of statistical mechanics, 3D-RISM-KH theory predicts

solvation structure and thermodynamics of nanochemical andbiomolecular systems, including their analytical long-range

asymptotics. It yields high accuracy, efficiency, and applicability by multiscale coupling of methods at different space and

time scales to provide fundamental understanding and prediction for nanomaterials and biomolecules. The method has

been coupled with quantum chemistry, molecular dynamics and dissipative particle dynamics. Examples include helical

rosette nanotubes with tunable stability and hierarchy, water promoted supramolecular chirality inversion, formation and

stability of self-assembling supramolecular structures of organic rosette nanotubes with ordered shells of inner and outer

water, aromatic hydrocarbons in kaolinite solutions, and accurate and efficient dissipative particle dynamics of polymer

chains with coarse-grained effective pair potential obtained from DRISM-KH theory. Multi-Time-Step molecular

dynamics with optimized isokinetic nose-hoover (OIN) thermostat coupled with 3D-RISM-KH molecular theory of

solvation and generalized solvation force extrapolation (MTS-MD/OIN/3D-RISM-KH/GSFE) provides quasidynamics

description of biomolecules. Validation included folding of miniprotein in solution from fully extended to equilibrated

state in 60 ns, which provides acceleration by two orders of magnitude time scale, compared to 4–9 µs protein folding in

experiment. Recent applications of 3D-RISM-KH molecular solvation theory consist in multiscale coupling of quantum

chemistry, molecular solvation theory, molecular dynamics, and dissipative particle dynamics.

Biography

Andriy Kovalenko is Senior Research Officer at the National Institute for Nanotechnology, and Adjunct Professor in the Department of Mechanical Engineer-

ing at the University of Alberta, Edmonton, Canada. He has completed his PhD in Theoretical and Mathematical Physics at Lviv State University, Bogoly-

ubov’s Institute in 1993. He has been developing methodology and software implementation of statistical-mechanical, molecular theory of solvation, coupling

it with electronic structure theories, molecular simulations, and docking protocols in a platform of predictive multiscale theory and modeling of chemical,

supramolecular, and biomolecular systems for new advances of a general framework of multiscale methods.
