Grazing Incidence X-ray Fluorescence
Synchrotron radiation provides a wide range of possibilities in the field of the analysis of materials and interfaces. In particular, methods involving X-rays under grazing incidence (GI) are ideally suited for the investigation of interface-related processes, as experiments are performed with high surface sensitivity. > more
Near ambient pressure X-ray photoelectron spectroscopy
In addition to a conventional XPS spectrometer, ISAS is operating one of the few laboratory near ambient pressure (NAP) XPS-spectrometers existing worldwide. The elemental surface composition and its spatial distribution, the quantities of the elements, the surface contamination, and the chemical state of the elements are the most important data obtained from the primary information in XPS-spectra, the core electron binding energies. . > more
Nuclear Magnetic Resonance (NMR)
NMR is an important topic for the Interface Processes group. NMR methods open up a path to the detection of light elements like carbon or phosphorus, which are either difficult to assess due to ubiquitios contaminations or due to wavelength, and they also allow for the investigation of hydrogen networks potentially influencing the ordering of molecules at surfaces. > more
Surface Plasmon Resonance Imaging
Recently, a new approach in SPR imaging was suggested, allowing the detection of single nanoparticles. The developed approach can be applied for characterization of nano particles of different sorts in liquid, gaseous or vacuum environments. Any particle bound on the sensor surface gives rise to a characteristic pattern with a light spot of few micrometers in diameter on the image. > more
