a, b Stress–strain curves of the micropillars compression of ZIF-8 and MIL-68, respectively. c Comparison of some representative ZIF-8 and MIL-68 stress–strain curves, obtained by compression under different strain rates. d, e Representative pillars before microcompression test (left), after test (middle) and magnified views of the ZIF-8 and MIL-68 monoliths after the tests (right).
