Germany-Brazil bilateral Workshop “New light on mechanisms of chemical reactions”

 

The development of new materials as well as the improvement and tunability of their structure-related properties such as luminescence, magnetism, particle or pore size on the atomic level depend on their rational synthesis. This goal can be achieved by elucidating the mechanisms behind the formation of solid materials like nucleation, crystal growth and/or phase transitions as well as the influence of synthesis parameters on these processes applying in-situ characterization techniques. Control of the crystal structure and particle morphology/size and therefore the structure-related properties is of eminent importance in a variety of advanced technological fields. For example, nanoparticulate luminescent materials are applied in the production of light-emitting diodes (LEDs), displays for laptops and mobile telephones. General nanosized materials are used in sensors, as selective markers for cell imaging or in advanced energy storage systems, while metal organic frameworks exhibit a large potential for gas sorption or in catalysis. Therefore, the rational development of such materials contribute for instance to the production of environmental friendly energy-saving electronic devices or for the advance of medical diagnosis. This workshop aims to combine the expertise of the German participants on studying mechanisms of formation of solid materials by in-situ characterization methods with the expertize of the participants of the universities of the Brazilian São Paulo state on the development of new functional materials exemplified above. Examples of discussed in-situ approaches are synchrotron-based in-situ X-ray diffraction (XRD) analysis, in-situ extended X-ray absorption fine structure (EXAFS), in-situ mass spectroscopy (MS), in-situ nuclear magnetic resonance (NMR), in-situ pair distribution function (PDF) and in-situ luminescence analysis of coordination sensors (ILACS).
