Webb29 nov. 2024 · The EQCM data was treated based on the Sauerbrey equation: Δm = −Cf∗Δf, where Δm is the change of mass of the coating and Cf is the sensitivity factor of the crystal. The sensitivity factor of the coated quartz was obtained by performing a copper deposition experiment conducted in 0.1 M CuSO 4 mixed with 1 M H 2 SO 4 by applying …
