Metrology with Synchrotron Radiation

High-energy density batteries play a crucial role for renewables, both as stationary storage system as well as for electric automotive applications. Every battery suffers under degradation effects leading to capacity and lifetime reduction. The understanding of the aging mechanism is mandatory for further cell improvement ...

In scanning probe microscopy (SPM) images of surfaces are created by moving a tip across the surface. Research in SPM aims to find suitable tips and physical interaction mechanisms which uncover specific surface properties. An important and proven method for mapping the magnetic order of ferromagnetic surfaces is magnetic force microscopy based on the magnetic dipole interaction ...

Fourier transform infrared (FTIR) spectroscopy is a powerful technique in analytical chemistry. Typically, spatially distributed spectra of the substance of interest are registered simultaneously using FTIR spectrometers equipped with array detectors. Scanning methods such as near-field FTIR spectroscopy are a promising alternative providing higher...
