Symposium Gas-phase Synthesis 2017

March 21 - 22, 2017 Symposium

Gas-phase Synthesis of Functional Nanomaterials:
Fundamental Understanding, Modeling and Simulation, Scale-up

Program at a Glance:
Gas-phase synthesis allows the production of a large variety of complex nanoparticles for various applications and is especially suited for scaling-up, already proven by several industrial processes. In this two-day international symposium at the UDE the fundamentals of particle formation and growth in relevant nanoparticle synthesis processes such as plasma and flame synthesis are presented. Furthermore, recent model-based approaches and simulation to predict synthesis processes and particle properties are discussed. Finally, the industrial-relevant scale-up of synthesis processes and possible applications of the produced nanomaterials are presented.

This international symposium is organized within the frame of the Horizon 2020 project Nanomaterials via Gas-Phase Synthesis: A Design-Oriented Modelling and Engineering Approach (NanoDome) and the DFG research unit (FOR 2284 Model-based scalable gas-phase synthesis of complex nanoparticles.
