“…They usually comprise pure metals such as Al and Ni, and can be prepared by multiple synthesis methods, including sputtering, evaporation, ARB and electrodeposition [31,121,127,128,144,362,[365][366][367][368]. The release of energy in reactive multilayers can be initiated by several techniques, including mechanical loading, thermal heating, laser heating or electrostatic discharge [31,127,128,144,[365][366][367][368]. The ignition starts a self-propagating reaction that is characterized by a high-temperature wavefront that propagates through the multilayer, which then transforms reactants into products [121,127,128,144].…”
