A mechanistic mathematical model is presented that describes the evolution of precursor nanoparticles (PN) to crystals. The model treats PN as pseudospecies evolving through an arbitrary number of reversible first-order steps and having the ability t

Precursor nanoparticles that form spontaneously on hydrolysis of tetraethylorthosilicate in aqueous solutions of tetrapropylammonium (TPA) hydroxide evolve to TPA-silicalite-1, a molecular-sieve crystal that serves as a model for the self-assembly of

Robust nonlinear feedforward–feedback controllers are designed for a multiscale system that dynamically couples kinetic Monte Carlo (KMC) and finite difference (FD) simulation codes. The coupled codes simulate the copper electrodeposition process f

The control of zeolite morphology is of interest because it will permit the rational design of products that have a wide array of applications, from catalysis to thin films for electronic devices. Over the past couple of years, some progress has been

During the initial stages of copper electrodeposition onto a thin seed layer, a nonuniform potential distribution arises, resulting in local variations in growth rate and deposit morphology. Early stages of morphology evolution during copper electrod

Chemical reacting systems involve phenomena that span several orders of magnitude in time and length scales, from the molecular to the macroscopic. To account for the multiscale character of these processes, many papers have adopted a simulation arch

A (2+1)D kinetic Monte Carlo (KMC) code was developed for coarse-grained as well as atomic-scale simulations that require detailed consideration of complex surface-reaction mechanisms associated with electrodeposition of copper in the presence of add
