We present the results of molecular dynamics simulations a nanoscale electrochemical cell. The include an aqueous electrolyte solution with varying ionic strength (
In this manuscript, we explore the electrostatic environment of interface between a solid and dilute electrolyte solution, with an emphasis on electric field profiles that these systems produce. We review theoretical formalism connects potential profiles, charge density fields. This has served as basis for our understanding interfacial fields their influences microscopic chemical physical processes. Comparing various traditional models electrostatics to results molecular dynamics (MD)...
We present a systematic study of ligand-mediated nanocluster (NC) formation using kinetic model, which provides atomic insight into sub-nanometer cluster (S-NC) and NC formation. Our model describes the role nucleation growth in obtaining monodisperse NCs. Nucleation includes metal ion reduction, reversible ligand association to ion/atom, dimer nuclei. Growth can occur through autocatalytic surface ligand-associated monomer addition cluster, depending on rate neutral atom conversion....
Understanding structure formation in polypeptide chains and synthetic polymers encapsulated pores is important biology nanotechnology. We present replica exchange molecular dynamics studies of the phase diagram for α-helix capped polyalanine nanotubes (NT) open to a water reservoir as function NT diameter hydrophobicity. A helix forms only narrow range diameters, which surprisingly comparable width ribosome tunnel. Increasing hydrophobicity enhances helicity NT. Helix driven by small...

Water-mediated interactions (WMIs) play diverse roles in molecular biology. They are particularly relevant geometrically confined spaces such as the interior of chaperonin, at interface between ligands and their binding partners, ribosome tunnel.
