Nanostructure and Functionality

Structure-Functionality at the atomic scale

The functionality of materials strongly relates to the structure of the materials down to the atomic scale. In catalysis, for instance the activity depends on the surface structure and composition of the active material. However, such surface structures and configurations reacts to the environment that be temperature, gas pressure, and gas composition. Monitoring the dynamics at atomic scale is key to understand the reactions and thereby materials with tailored functionality. In NanoFunc, our research is focused on developing electron microscopy based characterization techniques and methodologies to unravel the dynamics of nanomaterials at the atomic scale and relate them to functionality. 

The increased sensitivity and speed of modern detectors calls for novel approaches for analysis of the vast amount of data produced during experiments. Machine assisted analysis, such as machine- and deep learning is fundamental to the data treatment. Our goal is to bring such analysis into the electron microscopy data treatment in a robust and accessible way.

Applications of electron microscopy based in situ characterization in NanoFunc include, but are not limited to research within catalysis, growth of low-dimensional nanostructures (CNTs, graphene), oxidation processes, and layered 2D materials.
