Rupture strain as a function of the strain rate. In the box plots, the central mark indicates the median, and the bottom and top of the box indicate the 25th and 75th percentiles, respectively. The whiskers extend to the most extreme data points that are not outliers. Data points are indicated by grey dots and outliers, as red + symbols. Statistics: two-sided Kolmogorov–Smirnov test; ns, non-significant; ** P < 0.01, *** P < 0.001, **** P < 0.0001. Data from n = 6 monolayers for 0.1% s −1 , n = 9 for 0.3% s −1 , n = 10 for 1% s −1 , n = 11 for 2% s −1 and n = 11 for 3% s −1 . In a – e , the black dots represent individual monolayers, coloured dots represent the average value and whiskers indicate the standard deviations.
