Abstract: Ni$_3$Si$_2$O$_5$(OH)$_4$ phyllosilicate nanoscrolls were investigated by two techniques: the bending-based test method of AFM and the indentation method with visual control in STEM. In the first case, the average measured Young's modulus, about 200 GPa, turned out to be significantly higher than in the second one, 40 GPa. The reasons for this discrepancy are analyzed.

Keywords: AFM, in-situ TEM, nanomechanics, indentation, Young's modulus.
