Significantly enhanced energy output from 3D ordered macroporous structured FeO/Al Nanothermite Film

, 2013
A three-dimensionally ordered macroporous FeO/Al nanothermite membrane has been prepared with a polystyrene spheres template. The nanothermite, with an enhanced interfacial contact between fuel and oxidizer, outputs 2.83 kJ g of energy.

Microwave Ignition of Thermites

Propellants, Explosives, Pyrotechnics, Volume 49, Issue 10-11, October 2024.
Abstract This study investigates the microwave ignition behavior of a range of thermites of aluminum, boron, titanium, and tantalum fuels with oxides of Bi2O3, CuO, and Fe2O3. In order to gain insight into the modes of energy transfer leading to ignition, thermites are heated in either a purely electric or magnetic field environment within a single ...

Al/SnO₂ Nanothermite ESD Desensitization by Means of the Elaboration of Tailored SnO₂–Polypyrrole Composites

, 2023
Incidents can occur when handling energetic materials (EMs) due to their sensitivity to external stimuli. Mechanical (friction, impact) and electrical (electrostatic discharge (ESD)) stimuli can trigger involuntary ignition of EMs. Nanothermites, defined

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 ...

Ti/CuO and Ti/CuO/Cellulose Nitrate Nanothermites: An Early Insight into Their Combustion Mechanism

Energies
Most nanothermite compositions utilise Al as a fuel, due to its low cost, high reactivity and availability. Nevertheless, aluminothermites exhibit high ignition temperature and low active metal content.
