Hossein Rahbar has attended the 9th World Congress on Particle Technology (WCPT9) held in Madrid, Spain (Sep 18-22, 2022), to give an oral presentation on “Sintering of Nickel Nanoparticles by Molecular Dynamics” at this event. His project mainly focuses on finding process parameters that reduce aggregation during gas phase synthesis of nickel nanoparticles with the carbonyl process using multiscale process modeling. This model facilitates development of new types of nickel nanoparticles and could reduce the cost needed for process design and optimization.
