Nanoparticle growth, coalescence, and phase change in the gas-phase by molecular dynamics

Abstract

Gas-phase synthesis of nanomaterials offers distinct advantages in large-scale manufacturing of commodities such as carbon blacks, ceramic oxides, semiconductors, and dielectric substances and facilitates the formation of highly pure materials with unique morphology that impact transportation, microelectronics, catalysis, biomedicine, and energy applications. Particle characteristics such as size, morphology, composition, and crystallinity play a key role in the aerosol process design and operation optimization. Depending on process conditions and the growth mechanism, such nanostructured particles form aggregates which are used in catalysis, and electronics and/or agglomerates that are attr..
