Burning structures and propagation mechanisms of nanothermites

Proceedings of the Combustion Institute, 2023
Nanothermites demonstrate attractive combustion characteristics such as tunable reactivity and high energy density. There is however a lack of fundamental understanding on their burning structures and reaction mechanisms due to the multi-scale complexity associated with the material and reaction heterogeneities.

EU Regulation of Nanobiocides: Challenges in Implementing the Biocidal Product Regulation (BPR) [PDF]

, 2016
The Biocidal Products Regulation (BPR) contains several provisions for nanomaterials (NMs) and is the first regulation in the European Union to require specific testing and risk assessment for the NM form of a biocidal substance as a part of the ...

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 ...

Thermal behavior and combustion performance of Al/MoO3 nanothermites with addition of poly (vinylidene fluorine) using electrospraying

Materials Research Express, 2020
To investigate the effect of the addition of poly (vinylidene fluoride) (PVDF) on nanothermites, Al/MoO _3 /PVDF energetic nanocomposites were prepared using electrospraying method. As a control group, Al/MoO _3 was also designed. Then, both samples were

Charge‐Dipole Acceleration of Polar Gas Molecules towards Charged Nanoparticles: Involvement in Powerful Charge‐Induced Catalysis of Heterophase Chemical Reactions and Ball Lightning Phenomenon

Journal of Nanomaterials, Volume 2010, Issue 1, 2010., 2010
In humid air, the substantial charge‐dipole attraction and electrostatic acceleration of surrounding water vapour molecules towards charged combustible nanoparticles cause intense electrostatic hydration and preferential oxidation of these nanoparticles by electrostatically accelerated polar water vapour molecules rather than nonaccelerated nonpolar ...
