Brief description of the centre/research group (including URL if applicable) (max 1600 ch): 

ICN2's core activities include frontier and applied research in nanoscience and nanotechnology, technology transfer and public outreach. Its trustees are the Generalitat of Catalonia (Generalitat), the Spanish National Research Council (CSIC) and the Autonomous University of Barcelona, where it is located. It currently employs over 200 researchers, over half of which are from outside of Spain.

The Advanced Electron Nanoscopy Group contributes to the above research agenda by exploring the limits of electron microscopy to provide a greater understanding of the behaviour and properties of different materials. Growing interest in materials science has led to major global demand for characterisation tools for the observation and chemical analysis of synthesised nanostructures at the atomic scale. This group's research lines are based on single atom recognition and localisation. The group also works to develop new methodologies for performing direct correlations between the structural and chemical properties of materials at the atomic scale and their physical properties at sub-nanometre scale, together with a detailed atomic-level study of the growth mechanisms in nanostructures using 3D models.

Title of project: 

Scanning transmission electron microscopy and Integrated differential phase contrast imaging in environmental experiments for Tumbling the main players of a chemical reaction (SITO)

Project description (max 1600 ch): 

SITO aims at the in-situ characterisation of the nanostructures involved in catalytic reactions, through the imaging of both light and heavy elements to give direct information about the active sites and the reactive molecules. Recently, routes to materials synthesis have been improved to develop a new class of catalytic material, optimising atom utilization efficiency. The new electron microscopy technique developed in SITO contributes to this improvement as it promises the unprecedented identification of the reactive spots. This will be realised by using integrated differential phase contrast (iDPC)-STEM imaging combined with environmental microscopy. The newly introduced iDPC-STEM technique consists of the acquisition of electrons through the use of an annular detector split into four quadrants. Signal differences between two opposite quadrants are used to obtain the x and y component of the differential phase contrast. By further integrating these two components, an image is obtained where the contrast is linearly scaled with the atomic number. Here all the electrons in the bright field illumination cone are detected, such that light elements contribute a high signal-to-noise ratio. By combining this new imaging technique with dynamic in-situ experiments, it is possible to obtain unprecedented images where both the active sites of nanostructured systems and the reacting molecules appear in the same image.
