While the redox-reaction-based thermite mixtures for exothermic reactions are well-known since a long time, systematic research on non-thermite reactive materials dates back to the 1960s in the USSR when Merzhanov and Borovinskaya did groundbreaking work on powder-based transition metal/carbon mixtures. Since then, the class of ingredients has widened to include metal/metal mixtures and with the progress in physical vapor deposition, precise nanoscale layering of the reactant has become possible.

Al/Ni reactive multilayer systems (RMS) with a bilayer thickness of Λ=50nm and total thickness th=5μm on a SiO2 substrate exhibit a self-propagating reaction after ignition. A common method to initiate the self-propagating reaction is by electric spark ignition. In this work, RMS are ignited by a mechanical impact using various materials with indeterminate geometries to investigate the basic mechanisms.

1 Introduction So-called energetic materials inherently store a large amount of energy, mostly as chemical energy, and can show a fast and hot self-propagating exothermic reaction after ignition.[1-5] A well-studied class of such materials are reactive multilayer systems (RMS).[3-5] They consist of alternating thin layers of two or more elements. Systems like Pt/Al, Ti/B, Al/Ni, and more[6-8] have been developed and investigated over the last years.

Recent Progress in Transition Metal Based Catalysts and Mechanism Analysis for Alcohol Electrooxidation Reactions In order to address energy and environmental challenges effectively, there is a need to promote renewable energy-driven electrochemical conversion technologies, particularly electrosynthesis. Electrosynthesis has the potential to convert abundant molecules into valuable chemicals and fuels.
