• dissolution mechanism is mainly governed by simple diffusion, without significant swelling or erosion of the polymeric matrix [8], which is commonly observed in hydrophilic polymeric systems, as those produced by P407 [24]. In this context, the drug molecules diffuse through the micellar network driven by

• simplified Equation 3 circumvents the need to determine a Tafel slope for zinc dissolution. Importantly, the trend within a series of experiments will be correctly reproduced if the dissolution mechanism and hence the Tafel slope remains the same, as is expected for this system. The dissolution of zinc was

• fibrous structures (streaks) form at the step edges. Confocal Raman spectroscopy characterization of the reacted surface could not confirm if the formation of a secondary phase was responsible for the presence of these structures. Keywords: biotite; dissolution mechanism; environmental; in situ
