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 ...

A Melting‐Point Energy Window for Defect‐Induced Energy Release in Copper Nanoparticles

physica status solidi (a), Volume 223, Issue 7, 7 April 2026.
Point defects significantly modify the energetic landscape of copper nanoparticles during melting. Atomistic simulations reveal a distinct melting‐point energy window, where defect‐induced extra stored energy is sharply amplified and released. The results elucidate how defect concentration and particle size govern premelting instability, structural ...

Fluctuating Flame from Suspending Ferrimagnetic Core/Shell Al@Fe3O4 Nanoparticles in a Magnetic Field

Advanced Materials Interfaces, Volume 11, Issue 29, October 15, 2024.
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.
