Mechanical properties of Al2O3 inverse opals by means of nanoindentation [PDF]

open access: yes, 2016
In order to understand the mechanical behaviour of Al2O3 inverse opals, nanoindentation techniques have been implemented in material layers with three different microstructures, in terms of hollow or polystyrene spheres, with Al2O3 shells of distinct ...
