a Concentration of surface Si free radicals in low-energy crushed samples and high-energy crushed samples after 1 min incubation with anoxic water under an anoxic environment (n = 6). b H2O2 produced after two minutes of reaction of low energy and high-energy crushed samples with anoxic water under an anoxic environment (n = 6). The minimum and maximum values are represented by the whiskers, the interquartile range is represented by the box, and the median value is shown by the line in the centre of the box.
