My Research
My research focusses on the development and application of multimodal in-situ synchrotron based investigations for energy materials. I am combining X-ray absorption spectroscopy, X-ray diffraction and (X-ray) optical spectroscopy to access dynamic processes in-operando and in real-time, e.g. perovskite solar cell materials during synthesis, nano crystals during growth, catalysts in action or battery electrodes during rapid cycling.

Dr. Justus Just
Balder Beamline
I am working as a scientist at MAX IV Laboratory, Lund University. Together with my collegues I am managing the Balder beamline, which is dedicated to X-ray absorption spectroscopy (XAS) and X-ray emission spectroscopy (XES) in the medium and hard X-ray energy range, 2.4-40 keV. The high brilliance from the 3 GeV 4th generation storage ring in combination with the beamline design allows for real-time in-situ XAS measurements down to sub-second time resolution.
My particular interests are :
-
time-resolved real-time in-situ X-ray absorption spectroscopy (XAS)
-
XAS- based multimodal experiments with simultanous measurements of: X-ray diffraction (XRD) or X-ray excited optical luminescence (XEOL)
Projects
With in-FORM we develop a synchrotron based in-situ material research platform to gain insight into the formation of functional materials during deposition. This platform consists of a slot-die coating and annealing system with atmosphere control and a suitably small foot-print as well as flexibility for integration into the Balder beamline at MAX IV.

XRD@Balder: Synchronously combined in-situ X-ray diffraction and X-ray absorption spectroscopy for new catalytic materials
The collaborative project between Balder and Chalmers University, Göteborg, is aiming to develop and implement (in-situ) X-ray diffraction capabilities simultaneously with X-ray spectroscopy in one experimental setup with sub-second time resolution. This project is framed in the exploration of new catalytic materials, their molecular function and ways to use them for environmental protection and chemical production without putting planetary boundaries for sustainability at risk.
