Journal ArticleDOI
Ignition and explosion of nanopowders: something new under the dust
TL;DR: In this article, the authors studied the ignition and explosion characteristics of nanoparticles and found that as the particle size decreases, minimum ignition temperature and minimum ignition energy decrease, indicating higher potential inflammation and explosion risks for metallic nanopowders.
Journal ArticleDOI
The effect of agglomeration on the emission of particles from nanopowders flow
François Henry,Philippe Marchal,Jacques Bouillard,Alexis Vignes,Olivier Dufaud,Laurent Perrin +5 more
TL;DR: In this article, an original method was proposed to evaluate the possible emission of particles from a nanopowder submitted to a shear stress in dense phase and the resulting degree of agglomeration of the particles released.
Journal ArticleDOI
Rheology of powders and nanopowders through the use of a Couette four-bladed vane rheometer: flowability, cohesion energy, agglomerates and dustiness
TL;DR: In this article, a four-bladed vane powder rheometer is proposed to study powder and nanopowder rheology at low and high shear rates, where the powder flow will evolve from a Newtonian regime to a Coulombic regime and then to a kinetic regime, at which the powder may become self-fluidized because of intense particles collisions.
Journal ArticleDOI
Exploring a new method to study the agglomeration of powders: Application to nanopowders
François Henry,Jacques Bouillard,Philippe Marchal,Alexis Vignes,Olivier Dufaud,Laurent Perrin +5 more
TL;DR: In this paper, the structure and the dynamics of agglomeration of a nanopowder are evaluated based on monitoring of the shear stress of a powder which is submitted to the mechanical solicitation of a rheometer.
Ecoulements granulaires : approche rhéologique de l'agglomération des nanoparticules
François Henry,Jacques Bouillard,Philippe Marchal,Alexis Vignes,Olivier Dufaud,Laurent Perrin +5 more
TL;DR: In this paper, an approximation d'un taux maximal de desagglomeration peut etre infere de par les signatures des cisaillements rheologiques des nanopoudres.
