Shlomo Magdassi is a professor of chemistry, at the Casali Center for Applied Chemistry, the Institute of Chemistry and the Center for Nanoscience and Nanotechnology at the Hebrew University of Jerusalem, Israel. His research focuses on colloid science, and in particular on formation, formulation and applications of novel micro and nanoparticles. These particles can be used as active components in functional inks and coating, for example light absorbing particles for solar energy devices, and metal nanoparticles and CNTs for 2D and 3D printing. He is the editor of three books, among them “The chemistry of inkjet inks”. In addition to his scientific publications, he also has various inventions on applications of colloids in industrial products. Based on these inventions, some commercial activities evolved leading to worldwide sales and establishing new companies.
