World Congress on Particle Technology is intended to invite and encourage advanced research in the area of Particle Technology. The Special Topics area is intended for this very purpose. Over the last several decades, Particle Technology has transformed from an Art into Science and with the rapid development of instrumentation and computational power, there has been tremendous innovation in both experimental and modeling techniques for particulate systems. This has also enabled the development of a variety of novel low carbon processes which have particle technology at their core. The Special Topics area is a great platform for sharing these innovations. We invite papers related to: Application of Particle Technology in Sustainable Processes such as biofuels and biomass conversion Advanced experimental techniques in all aspects of particulate systems Advanced modeling techniques for particulate systems – both Discrete as well as continuum approaches Industrial applications of experimental and computational particle flows
