Cobalt-free curing of alkyds and of vinylester-styrene coatings
Many coatings dry via chemical crosslinking reactions, which are catalyzed by transition metal complexes. The toxicity of some of these metals is under review currently. In this project, we will search for alternative catalysts based on transition metals that avoid potential toxicity.

Polyester synthesis using novel and efficient esterification catalysts
Aim of this project is to develop new catalysts for polyester syntheses with an attractive environmental and economic profile. These catalysts will lead to more eco-friendly processes and will broaden the scope of raw materials (including renewable-based raw materials) that can be used in polyester syntheses.

Perovskite crystallization for stable and large scale printable solar cells
The project aims at obtaining fundamental insights in the processes that govern perovskite thin film formation and crystallization for photovoltaic applications. Crystallite size, crystallite orientation, surface coverage, surface roughness and interaction with the receiving surface are crucial parameters that determine the solar cell performance. One of the principal issues in perovskites currently revolves around stability. The significant strides made in recent time provide the opportunity to comfortably think of large scale deployment. Scale-up of printing technology to GWp/a scale, necessary to impact global energy systems, requires intimate knowledge on the crystallization processes and their dependence on process conditions. Using a range of in-situ spectroscopic and X-ray diffraction techniques the mechanisms and kinetics of crystallization of organometal perovskite layers will be investigated in real time during film formation. This will provide guidelines to develop large scale and fast roll-to-roll printing processes for this promising new energy technology.
