In the original publication [1], minor mistakes were present in Figure 2 and Table 1. The plots for both the 35 and 40 h milling times are identical. This error occurred during data transfer from the text file to the original software. Instead of copying the data from the 35 h text file (to plot the Raman spectroscopy for the 35 h milling time), the data was copied from the 40 h text file. Hence, the data for the 40 h milling time was copied twice, and this resulted in identical curves for the results at 35 h and 40 h. We did not notice this because the difference in the data for each sample is minimal. Using the original data for the 35 h milling time, we replotted the curve and corrected Figure 2.
