“…Electrochemical Quartz Crystal Nanobalance Electrochemical Quartz Crystal Nanobalance (EQCN) data was obtained using an ELCHEMA model EQCN-700 and was used in order to track a change in frequency and in turn small, interfacial mass changes. This relationship between mass per unit area (Δm) and the resonant frequency (Δf) is given by the Sauerbrey equation 21 , which assumes that the combination of the crystal and the absorbed mass behaves as a rigid assembly. Specifically, 0.1 wt% CeO2 in ethanol was used to deposit a film onto a gold electrode as shown in Figure 2.…”

“…In particular, in chemical mechanical planarization (CMP) applications, the interaction of ceria particles with SiO 2 films has been extensively studied to understand the influence of slurry chemistry, interaction force and particle adsorption on SiO 2 films and particle removal during polishing and cleaning, respectively [5,6,7,8]. Many studies have demonstrated that atomic force microscopy (AFM) and the quartz crystal microbalance-dissipation (QCM-D) can be used to investigate the particle-surface interaction forces and the adsorbed amount, respectively [8,9,10,11]. AFM colloidal probe technique has been widely used to measure directly the interactions between ceria particles and surfaces.…”

“…With its nano-gram sensitivity, QCM is an ideal technique to study the tendency for particle-substrate interactions in changing chemical environments. Rafie Borujeny et al 5 considered the effect of suspension pH on the interaction between silica (QCM sensor) and ceria nanoparticles. By varying the ceria slurry pH between 3 and 10, the authors observed high rates of particle deposition at pH 3 and pH 7, and much lower particle deposition rates (< 1 ng/cm 2 .s) at pH 10.…”
