(488a) Fine Particle Systems – a Personal View on Multidimensional Particle Characterization

Reg Davies was an outstanding pioneer of particle science and technology. His PARSAT team at Dupont belonged to the best and most influential groups in industry worldwide. A long-term vision in particle science and technology is the targeted design of particulate products including their surfaces, as mentioned by Reg in his outstanding review Particle Science and Technology – a view at the millennium. Starting from his views on the future of fine particle systems I will describe progress in systematic approaches to rigorous optimization of particle formation, formulation and characterization based on predictive structure-property and process-structure functions. As Reg was also a pioneer in particle characterization, I will discuss recent developments in multidimensional characterization of particles with respect to size, shape, composition and surface properties for a range of different material systems. Recent developments in multiwavelength analytical ultracentrifugation and nanoparticle chromatography in the liquid phase as well as electrospray-assisted mobility-classified mass spectrometry in the gas phase allow nowadays the precise and amazingly accurate multidimensional and multimodal characterization of fine particles.
