Understanding nano-impacts: Reversible agglomeration and near-wall hindered diffusion

The effects of reversible agglomeration and near-wall hindered diffusion are investigated in the context of nano impact experiments. A significant reduction in the mass transport to the electrode is observed due to the formation of slow-moving agglomerates. It is further demonstrated that in the presence of a rapid agglomeration process, larger agglomerated species are virtually unobservable, since the monomer is the dominant flux carrier. This observation is consistent with previously reported experimental data. (C) 2016 Elsevier B.V. All rights reserved.
