Journal ArticleDOI
Stable prenucleation mineral clusters are liquid-like ionic polymers
TL;DR: It is shown, using computer simulations combined with the analysis of experimental data, that these early stages of calcium carbonate formation are made of an ionic polymer, composed of alternating calcium and carbonate ions, with a dynamic topology consisting of chains, branches and rings.
Journal ArticleDOI
Derivation of an accurate force-field for simulating the growth of calcium carbonate from aqueous solution : a new model for the calcite-water interface
TL;DR: In this article, a force-field model based on rigid carbonate ions was developed that accurately describes the thermodynamics of the aqueous calcium carbonate system within molecular dynamics simulations.
Journal ArticleDOI
Gas hydrate nucleation and cage formation at a water/methane interface
TL;DR: It was found that hydrate initially nucleates into a phase consistent with none of the common bulk crystal structures, but containing structural units of all of them, as well as the process of water cage formation, which has been found to correlate strongly with the collective arrangement of methane molecules.
Journal ArticleDOI
Nucleation of NaCl from Aqueous Solution: Critical Sizes, Ion-Attachment Kinetics, and Rates.
TL;DR: Sodium chloride nucleation from supersaturated brines is investigated using seeded atomistic simulations, polymorph-specific order parameters, and elements of classical nucleation theory to find that NaCl nucleates via the common rock salt structure.
Journal ArticleDOI
Metadynamics simulations of ice nucleation and growth
David Quigley,P. M. Rodger +1 more
TL;DR: This work demonstrates homogeneous nucleation and growth of ice at 180 K in the isothermal-isobaric ensemble without the presence of external fields or surfaces, the first report of continuous and dynamic ice nucleation in a system of freely evolving density.
