The Solids Processing Group is currently working on the following projects
1. DFG CRC 814 Additive Manufacturing (07/2019 to 07/2023, 750 k€)
Within the Collaborative Research Centre (CRC), the group is looking into particle formation processes for the design of multi-component polymer and metal powders. The aim is the production of new compound material that allows designing local and global properties of parts in selective laser sintering processes. The research is funded by the German Research Foundation (DFG).
2. High-temperature polymer powders for selective laser sintering (07/2019 to 06/2022, 350 k€)
Together with an industrial partner, new process routes for the production of high-temperature polymer powders for use in selective laser sintering are developed. The research is funded by the Free State Bavaria within the Research Programme “New Materials”. The project is coordinated by the Projektträger Jülich GmbH (PTJ Jülich).
3. High-impact polypropylene powders for selective laser sintering (04/2019 to 03/2021, 190 k€)
Together with a network of industrial partners, new process routes for the production of easily colourable high-impact polypropylene powders for use in selective laser sintering are developed. The research is funded by the German Federal Ministry for Economic Affairs and Energy (BMWi) within the ZIM programme. The project is coordinated by VDI/VDE-IT.
4. Simulation of tablet coating in drum coaters (12/2019 to 11/2022, 260 k€)
Together with partners from industry and academia, a new approach on tablet coating in rotating drums is pursued. In a combination of modelling and experiments, micro-, meso and macroscale processes are considered. The aim is the establishment of new correlations and short-cut models for coating efficiency, accurracy and yield. The research is funded by Bayerische Forschungsstiftung (BFS).
5. DFG CRC 1411 Design of Particulate Products (01/2020 to 12/2023, 385 k€)
The objective is the development of a new scalable technology for continuous production of stationary phase materials for use in particle chromatography from suspensions by “spray printing”, i.e. layer-by-layer build-up of functional, porous substrates by individual droplet placement and drying. We will design and implement a new device for layer-by-layer build up. We will perform experiments on solids formation from drying free and sessile droplets and derive dynamic models that will allow describing predictively layer morphology and spatial heterogeneity of the porous substrates.
6. Fundamental investigation of comminution behaviour in a fluidized bed opposed gas jet mill (03/2020 to 02/2021, 65 k€)
Within this project the comminution behaviour in fluidized bed opposed gas jet mills is numerically modelled. The aim is the development of a new model that allows prediction and design of the equipment given material parameters. This work is jointly funded by CAPES (Brazilian Research Foundation) and the Alexander-von-Humboldt Foundation.
7. DFG PP 2289: Formulation of hetero-aggregates in continuously-operated opposed jet fluidised beds (10/2021 to 09/2024, 305 k€)
The vision of the project is the establishment of a scalable continuous process for formulation of multinary hetero-aggregates from dry primary particles as an alternative to flame synthesis and aerosol processes. The functionality of the hetero-aggregates will be grounded in the designed composition and distribution of hetero-contacts between constituents achieved by mixing at the primary particle scale (~ 10 nm).
