Abstract:The growth of silica nanoparticles by agglomeration and viscous flow sintering is studied from free molecular to transition regime by off-lattice event-driven (ED) simulations. Coagulation by simultaneous agglomeration and sintering takes place at high temperature environments, where sintering and collision rates are comparable. The effect of temperature on aggregate mobility and gyration radii, particle morphology, and collisional enhancement is elucidated. The ratio between the characteristic sintering time … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
