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 ...

Reduced-Sensitivity Nanothermites Containing Manganese Oxide Filled Carbon Nanofibers
, 2016 Nanothermites are versatile pyrotechnic systems composed of a metal oxide and a reducing metal powder, such as aluminum. The high mechanical sensitivity of some of these mixtures (e.g., MnO2/Al) makes their handling hazardous.

The initiation temperatures in nanothermite reactions
, 2019 An assumption on general regularities and chemical mechanisms of solid-state reactions in nanofilms and nanothermite mixtures is made. It is demonstrated that the moving force of all Al-based nanothermite reactions is the synthesis of the Al2O3 phase with a high negative enthalpy of formation.

Сombustion of Micro- and Nanothermites under Elevating Pressure
Physics Procedia, 2015 AbstractNon-equilibrium process of combustion-wave propagation of thermite compositions (Mg/Fe2O3) inside the sealed steel tube have been investigated to study the burning rate at elevating pressure. Under confinement the hot gas-phase products, formed during thermite combustion result in considerable overpressure inside the tube that reverses the gas ...

Effect of additives on CuO/Al nanothermite properties
Journal of Physics: Conference Series, 2017 The effect of additives on CuO/Al nanothermite properties is reported. The incorporation of additives resulted in the decreased sensitivity. It had an adverse impact on gas dynamic characteristics of CuO/Al nanothermite, up to the loss of the unique capability of burning in narrow channels.
