ABSTRACT
We develop process technologies for synthesis, formulation and application of functional particle systems. This contribution shows how particle technology moves forward from careful control of “only” particle size to systems with higher complexity both on the level of single particles and particle ensembles. Today, other disperse properties beyond size, i.e. particle shape, particle surface, particle structure and particle composition are in the focus. We highlight aspects of these trends towards higher complexity by focusing on self-assembly and particle aggregation by oriented attachment of discrete clusters and quantum dots into well-defined structures of rods, ellipsoids, mesocrystals, porous spheres and thin films, all with interesting functional properties. The amazing aggregation processes may lead to well-organized and highly regular structures beyond the classical picture of fractal aggregates. Applications include printable electronics, solar cells, catalyst materials and particles for additive manufacturing.

ABOUT THE SPEAKER
Dr. Wolfgang Peukert is a Full professor for Particle Technology at the Department of Chemical and Biochemical Engineering of the University of Erlangen-Nürnberg, Germany (since 2003). Previously, he was a Full professor for Particle Technology at Technical University Munich (1998-2003), a Board member of Hosokawa Micron Int., New York (1997-98) and the R&D Director at Hosokawa MikroPul (1993-98). He obtained his doctorate and diploma in chemical engineering from the University of Karlsruhe, Germany, in 2000 and 1984, respectively. He has won several awards including the Ernest Solvay Prize in 2012, Leslie Ford Lecture in the UK Particle Technology Forum in 2008 and the Gottfried Wilhelm Leibniz Prize in 2005. His research areas include applications of particle science and technology in chemical engineering, materials science, nanotechnology, colloid science, biotechnology, environmental science and product design of nano- and mesostructured particles.
