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

Download high-res image (121KB)Download full-size imageThe 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.
