Abstract
In the above paper, the y-axis label of Figure 1 was incorrect. The y-axis label should read “Δf / Hz”and the corrected figure is shown below as Figure 1. Salt-concentration (Csalt) dependence of the frequency shift (Δf) of PMETAC brushes in the presence of different types of counterions with Na+ as the common cation. Here, the overtone number (n) is 3. The authors apologize for this oversight.
