Evaluation of interaction forces between nanoparticles by molecular dynamics simulation / Qinghua Zeng in Industrial & engineering chemistry research, Vol. 49 N° 24 (Décembre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 24 (Décembre 2010) . - pp.12793 -12797 Titre : Evaluation of interaction forces between nanoparticles by molecular dynamics simulation Type de document : texte imprimé Auteurs : Qinghua Zeng, Auteur ; Aibing Yu, Auteur ; Gaoqing (Max) Lu, Auteur Année de publication : 2011 Article en page(s) : pp.12793 -12797 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Shape  controlled  synthesis  Microscope  Crystals  Surface Résumé : Molecular dynamics simulations are used to quantify the interaction forces between nanoparticles, which are critical to nanoparticle systems. It is shown that the fluctuation of surface atomic density and the dynamics of collisions significantly affect the interaction forces. As a result, the Hamaker method cannot accurately estimate the interaction forces for nanoparticles. The proposed approach offers an effective method for determining the interaction forces between nanoparticles. © 2010 American Chemical Society.
