For flow-EQCM experiments, an EGG Princeton Applied Research Model 273A system was used and frequency changes were displayed on a Kipp and Zonen Model BD111 single pen chart recorder. A Gilson Minipuls 3 peristaltic pump was used to deliver solution to the flow–EQCM system and a Valco Model 6-way slider valve equipped with 0.15 mm i.d. tubing was employed to switch and inject solutions at a nominal flow rate of 0.28 mL/min. The flow rate and a cell volume (about 0.5 mL) were enough for the deposition of thin films considering the concentration of Cu2+ and Se4+ ions. Evaluation only.
