Reply to the ‘Comment on “Crystal growth and aggregation in suspensions of δ-MnO2 nanoparticles: implications for surface reactivity”’ by A. Manceau, Environ. Sci.: Nano, 2018, 5, DOI: 10.1039/C8EN00126J
Abstract
In his comment on our initial article (Marafatto et al., Environ. Sci. Nano, 2018, 5, 497), Manceau challenges the approach used to model the X-ray diffraction (XRD) patterns and the actual coherent scattering domain size values derived using this approach (Manceau, Environ. Sci.: Nano, 2018, DOI: 10.1039/C8EN00126J). The present reply clarifies the conservative assumptions underlying the XRD modeling performed in the initial article. These assumptions aimed (i) at providing apparent particle sizes consistent with the objectives of the initial article and (ii) at not over-parameterizing the model in the absence of quantitative experimental constraints.
