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 ...

Ignition of nanothermites by a laser diode pulse

Defence Technology, 2022
Experimental investigation has been carried out for laser ignition and combustion of nanothermites based on aluminum and oxides of copper, bismuth and molybdenum. Ultrasonic mixing of nanosized powders was used to produce compositions. For thermite ignition, initiating laser pulse with a maximum intensity of 770 W/cm2 was generated by a laser diode ...
