- ... Conductive-tip atomic force microscopy (CAFM) was used to explore the effects of high electric fields on silver nanoparticle (NP) arrays embedded inside the pores of mesoporous TiO₂ thin films (MTF). A controlled local modification of the distribution of Ag nanoparticles inside the MTF and their electronic transport properties was carried out. The process is driven by strong electrochemically indu ...

- ... Electrochemical processes at water–titania interfaces in TiO₂ thin films were studied using conducting-tip atomic force microscopy. Mesoporous titania thin films were prepared by sol–gel synthesis from molecular precursors with the addition of surfactants to induce the formation of a porous structure. We found that both three-dimensional local resistance and topography are significantly and irreve ...
