Fluidization of Fine Powders

José Manuel Valverde Millán is Assistant Professor in the Department of Electronics and Electromagnetism, Faculty of Physics, University of Seville. He is an Associate Editor of the Journal of Nanoparticle Research. His research activity is interdisciplinary and lies between engineering and fundamental physics. A major contribution of his studies was the development of a novel powder tester, which earned him an award by Xerox Co.. He also received the Outstanding Researcher Award by the International Iberian Nanotechnology Laboratory- INL. He has authored 73 journal papers, 4 educational monographs, 5 patents.  He has carried out detailed studies on the fluidization and mechanical properties of fine powders. This work is aimed at formulating models for a deeper understanding of the special behaviour of powder systems. A main subject of his studies has been the development of synthetic powders with enhanced CO2 capture efficiency.
