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.

Controlled Substrate Destruction Using Nanothermite
Propellants, Explosives, Pyrotechnics, 2017 The experiments described in this paper look to further transient electronic device development by exploring the fracturing capabilities of aluminum copper (II) oxide and aluminum bismuth (III) oxide nanothermites. In particular, a quick, inexpensive test was developed that was able to characterize the substrate fracturing capability of these ...
