This article reports on the fabrication and microstructures of novel Al@Fe3O4 core–shell composite nanoparticles. Thermal analysis suggests the as‐prepared particles predominantly go through a solid‐state reaction mechanism that exhibits 30% lower activation energy compared to physically mixed nanocomposite.

Microwave Ignition of Thermites
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 ...
