ESR for individual parallel 0% glycerol samples over the temperature range (averaged values in Fig. 2b). It should be noted that the black points represent the reference samples, which have been held at room temperature at all times. However, they are marked to the temperature of the corresponding measurement round to provide reference for the aging of the samples over multiple measurement cycles.
