Functional Nanoparticulate Synthesis and Applications
The lecture will introduce the controlled design of functional nanoparticles in connection with specific applications. The content will comprise an introduction to the basic synthesis methods of gas phase made particles including various spray and flame reactors.
The lecture will focus on flame aerosol technology which is one of the most widely used synthesis routes in manufacturing of commercial quantities of nanoparticles. The application of flame spray pyrolysis further broadens the spectrum of flame made powders as there are more liquid than gaseous precursors available. It will be shown how key process parameters provide unique opportunities for particle design and control.
The presentation will comprise the manufacture of mixed metal oxides (ceria/zirconia), the formation of stable quantum dots (ZnO embedded in silica) and the simultaneous deposition of precious metals (e.g. Pt, Au) on the formed ceramic support during the FSP synthesis. Tailoring of specific particle properties will be discussed with regard to specific applications such as heterogeneous catalysis, polishing materials, UV-filters, sensors and dental fillers. Future opportunities such as the direct deposition of gas phase made particles on sensor substrates in relation to their performance will be given.

Who Should Attend
Professionals working in the applied fields of chemistry, chemical engineering, materials science, polymer engineering, biochemistry, bioengineering, biomedical engineering and physics will find great value in this course as it brings in a condensed format an overview of this rapidly evolving field. Such professionals might be involved in research and development of processes like fine particles for batteries, films, phosphors, catalysts, polishing, medical and dental nanocomposite materials (prosthetics), pigments, optical fibers, precious metals (Ag, Au, Pt, Pd), sunscreens, cosmetics, fuel cells, solar energy storage, or polymeric materials, with an interest in expanding their area of expertise to nanoparticles. Professionals in science and engineering management, or strategic development, will benefit by gaining a better understanding of this field for their planning purposes.
