The role of viscosity on ion transport in thin-layer electrodeposition

The effects of viscosity variation on ion transport and growth morphology, under constant electric current and convection prevailing regimes , is studied through experiments and computational modeling. The viscosity was changed through glycerol addition. Optical techniques and particle image velocim...
