Sotiris Emmanuel Pratsinis

Sotiris Pratsinis is Professor of Process Engineering and Materials Science at ETH Zurich, Switzerland. He has ChE Diploma from Aristotle University of Thessaloniki, Greece and MSc/PhD from University of California, Los Angeles. His research centers on particle dynamics for synthesis of novel functional materials. He teaches Mass Transfer & Micro-Nano-Particle Technology, has graduated 40 PhD students (at leading industrial and academic institutions worldwide today), published 400+ refereed articles, received 20+ patents that are licensed to industry and have contributed to creation of four spinoffs.    He pioneered the creation of robust algorithms for agglomerate dynamics (two-dimensional population balances) that are interfaced readily with fluid mechanics, facilitating multiscale process design for manufacture of particulate commodities and lightguide preforms. He has shown experimentally how to closely control particle size, crystallinity and morphology, from perfectly spherical to fractal-like structures.  He resolved the toxicity origin (ions or particles) of nanosilver (one of the most widely used nanomaterials) that had challenged early on its broad application. He developed the flame spray pyrolysis process for scalable synthesis of films and particles creating new (e.g. single atom) catalysts, gas sensors for breath analysis, nutritional supplements, bioimaging and dental materials. He is member of the Swiss Academy of Engineering.
