The original version of this Article contained errors in the third and fourth sentences of the legend to Table 1, which incorrectly read ‘The hardness was computed using the Chen–Niu model23, the fracture toughness—using the Niu–Niu–Oganov model27. Refs. a40, b41, c52, d53, e58, f59, g60, h61, i62, j63, k64, m66, n67, p68, q69.’ The correct version revises all references and states ‘The hardness was computed using the Chen–Niu model72, the fracture toughness—using the Niu–Niu–Oganov model74. Refs. a29, b30, c43, d44, e49, f50, g51, h52, i53, j55, k56, m58, n57, p54, q59.’ This has been corrected in both the PDF and HTML versions of the Article.
