Burning structures and propagation mechanisms of nanothermites
Proceedings of the Combustion Institute, 2023 Nanothermites demonstrate attractive combustion characteristics such as tunable reactivity and high energy density. There is however a lack of fundamental understanding on their burning structures and reaction mechanisms due to the multi-scale complexity associated with the material and reaction heterogeneities.
