In the original article, there was a mistake in the legends for Figures 3, 4, 7, and 8 as published. In these Figures, marks such as a, b, c, d, e, f, and g have not been explained. The updated legends appear below.
Figure 3. (A) UV-vis spectra and (B) main peak positions of DHM refluxed for different times. (a) DHM; (b–g) DHM refluxing for 30, 60, 90, 120, 150, and 180 min.
Figure 4. (A) UV-vis spectra and (B) main peak positions of DHM stirred for different times at pH = 8.2. (a) DHM; (b–g) DHM stirring for 1, 3, 5, 10, 20, and 30 min in pH 8.2.
Figure 7. EPR spectra of DHM in air-, nitrogen-, and oxygen-saturated alkaline solutions. (a) DHM only; (b) DHM + DMPO; (c–e) DHM + DMPO, in nitrogen-, air-, oxygen-saturated alkaline solution.
Figure 8. EPR spectra of superoxide-anion radical generation from DMSO reacted with a base in the presence of oxygen. (a) DMSO + DMPO + O2; (b) Na+PhO− + DMPO + O2; (c) Na+PhO−+O2; (d) DMSO + Na+PhO− + O2; (e) DMSO + Na+PhO−+ DMPO + O2.
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
