Chemistry and biology at micro-scale interfaces play a significant role for the understanding of the functioning of eco- and climate systems at the macro-scale. Improved mechanistic understanding of processes occurring at interfaces, e.g. biosphere-atmosphere and hydrosphere-atmosphere, is vital for the prediction of our future climate.
In nature many processes are occurring simultaneously resulting in an inherent complexity at environmental interfaces. To disentangle such a complexity, we are using a novel combination of X-ray absorption spectroscopy (XAS), X-ray photoemission spectroscopy (XPS), thermal analysis (isothermal microcalorimetry, thermo-gravimetric analysis) and microscopy techniques (scanning electron microscopy, mass spectrometry imaging) together with stable isotope chemistry.
