Assistant Professor Kirsten Ørnsbjerg Jensen receives funding: EUR 1.4 million from the EU

Assistant Professor Kirsten Ørnsbjerg Jensen, Department of Chemistry and Nano-Science Center, University of Copenhagen, has received a ERC Starting Grant from the European Research Council of EUR 1.4 million for a research project titled MatMech; Live Tapings of Material Formation: Unravelling formation mechanisms in materials chemistry through Multimodal X-ray total scattering studies

Kirsten tells this about the project:
The aim of the project is to develop a unified view of metal oxide nucleation processes on the atomic scale: From precursor complexes over pre-nucleation clusters to the final crystalline particle. The development of new materials relies on our understanding of the relation between material structure, properties and synthesis. While the intense focus on ‘materials by design’ has made it possible to predict the properties of many materials given an atomic arrangement, actually knowing how to synthesize it is a completely different story. Material synthesis methods are to a large degree developed by extensive parameter studies based on trial-and-error experiments. Specifically, our knowledge of particle nucleation is lacking, as even non-classical views on nucleation such as the concept of pre-nucleation clusters do not apply an atomistic view of the formation process. Here, I want to use new methods in Xray total scattering and Pair Distribution Function analysis to follow nucleation processes to establish the framework needed for predictive material synthesis. One of the large challenges in studying nucleation is the lack of a characterization method that can give structural information on materials without long-range order. I have demonstrated that time-resolved X-ray total scattering gives new possibilities for following structural changes in a synthesis, and the use of total scattering has opened for a new view on material formation. However, the complexity of the structures involved in nucleation processes is too large to obtain sufficient information from X-ray total scattering alone. Here, I will combine X-ray total scattering data with complementary techniques using a new multimodal approach for complex modeling analysis, providing a unifying view on material nucleation.
