Incomplete reactions in nanothermite composites. [PDF]
Exothermic reactions between oxophilic metals and transition/post transition metal-oxides have been well documented owing to their fast reaction time scales (≈10 μs). This article examines the extent of the reaction in nano-aluminum based thermite systems through a forensic inspection of the products formed during reaction.

Group Combustion of Dispersed Spherical Core–Shell Nanothermite Particles
The group combustion characteristics of core–shell nanothermite particles differ from other dispersed solid or liquid fuels. In a core–shell structure, each discrete nanothermite particle can undergo an exothermic reaction as the oxygen atoms in the ...

The initiation temperatures in nanothermite reactions [PDF]
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.

Coulomb Effect of Intermediate Products of Core–Shell SiO2@Al Nanothermite [PDF]
Nanothermites as high-energy-density and high-reaction-rate materials have important applications in civil and military fields. Nevertheless, it is difficult to detect all intermediates and products using conventional experimental methods.

Abrupt Transition of Nanothermite Reactivity: The Roles of Loading Density, Microstructure and Ingredients [PDF]
Nanothermites are widely applied as specific power sources for microscale initiators and pyrotechnics. Increasing the charge density enhances energy storage within a confined combustion chamber, but it also alters the reaction kinetics.
