“…Such advanced nanoscale materials as catalysts and electrocatalysts, 1,2 electromechanical actuators, 3,4 battery and filtration materials 5,6 exhibit their new functionalities due to the changes in their local structures and electronic properties that occur within a range of a few interatomic distances. 1,7 There is a paucity of either available experimental methods or a dedicated research infrastructure in the case of materials in which the response to the external stimulation is weak. In the first class of such materials, such as piezoelectrics, ferroelectrics, classical electrostrictors, and magnetostrictors, 3,8,9 the structural or electronic responses to the external excitation are uniform but weak.…”
