Research description

Core-shell nanoparticles have much-highlighted potential applications in heterogeneous catalysis, energy storage and medical applications. There is currently one big catch: we have no idea how to make large quantities and are essentially limited to labscale processes. My research focuses on the coating of nanoparticles in the gas phase with atomic layer deposition (ALD): a technique from the semi-conductor industry that can deposit a wide range of materials. The challenge is to understand how nanoparticles agglomerate to loose dynamic clusters and understand the agglomeration process in gas flows during coating, such that uniform coatings can be made.

I will aim at developing numerical models for the gas dynamics in fluidized beds with agglomerates of nanoparticles, their interaction and coating. Since the relevant length scales range form nm to cm, a multi-scale modelling approach is well expected.
