Traditional technologies used to manufacture current pyrotechnic switches are based on synthesis, pressing/casting and injection of macroscopic organic energetic materials (explosive or highly energetic materials), which leads to bulky and dangerous systems. We propose, instead, a nanothermite-based safety switch, which provides a compact...

Aluminum as fuel has demonstrated compelling attributes over decades of research, including affordability, abundance, and a high specific energy density. It stands out as the most extensively studied metallic fuel 1,2 . However, Al faces a challenge in the form of a high ignition point, primarily attributed to the presence of its native oxide....

This paper describes a kinetic model dedicated to thermite nanopowder combustion,in which core equations are based on condensed phase mechanisms only. We explore all combinations of fuels/oxidizers, namely Al, Zr, B/CuO, Fe2O3, WO3, and Pb3O4, with 60 % of thetheoretical maximum density packing, at which condensed phase mechanisms govern the...

This work presents a triggerable ultimate security device (USD) capable of physically destroying a memory chip that contains classified data within a few milliseconds upon the detection of intrusion. The USD is designed as an add-on module that can be positioned onto any electronic chip, IC circuit, or memory card without requiring any...
