HZB and Freie Universität Berlin establish the joint research group “X-Ray Microscopy” for studying complex cellular processes

In May this year, the joint research group “X-Ray Microscopy” was launched, combining the expertise of teams led by Prof. Dr. Gerd Schneider (Helmholtz-Zentrum Berlin) and Prof. Dr. Helge Ewers (Freie Universität Berlin). While Ewers’ group contributes its experience in the field of optical microscopy and biological research, the HZB workgroup is responsible for X-ray microscopy at the synchrotron source BESSY II. The two methods help researchers to gain a detailed insight into the processes taking place inside cells.

We are very pleased about the new cooperation with Prof. Ewers’ workgroup. It gives our own activities in this field a much stronger connection to the biological research being done at the university,” says Prof. Dr. Gerd Schneider. The core duties of his department at HZB include making advancements to the x-ray microscopes and lenses at the synchrotron source BESSY II. The active exchange between the new cooperation partners will give a new boost to method development, says Schneider. Prof. Dr. Helge Ewers is also excited about the future-oriented cooperation: “X-ray microscopy opens up entirely new possibilities for us in the research of intracellular processes.”

The joint research group is all about the complementary use of optical and X-ray microscopy. Optical microscopy and super-resolution methods are excellent for locating proteins marked with dye molecules in tissue samples. X-ray microscopy, in turn, allows correlative imaging of the distribution of proteins, viruses or nanoparticles over a relatively large section in high-resolution and three-dimensions. The two microscopy methods thus deliver a comprehensive picture of the intracellular structures and processes.

After a successful upgrade, the X-ray microscope TXM at the synchrotron source BESSY II is now available again to users. Aside from biological studies, which can now be conducted with the combined expertise in the joint research group, the X-ray microscope is used above all for exploring various questions of materials and energy research.

    Spintronics at BESSY II: Domain walls in magnetic nanowires
    Magnetic domains walls are known to be a source of electrical resistance due to the difficulty for transport electron spins to follow their magnetic texture. This phenomenon holds potential for utilization in spintronic devices, where the electrical resistance can vary based on the presence or absence of a domain wall. A particularly intriguing class of materials are half metals such as La2/3Sr1/3MnO3 (LSMO) which present full spin polarization, allowing their exploitation in spintronic devices. Still the resistance of a single domain wall in half metals remained unknown. Now a team from Spain, France and Germany has generated a single domain wall on a LSMO nanowire and measured resistance changes 20 times larger than for a normal ferromagnet such as Cobalt.

    How much cadmium is contained in cocoa beans?
    Cocoa beans can absorb toxic heavy metals such as cadmium from the soil. Some cultivation areas, especially in South America, are polluted with these heavy metals, in some cases considerably. In combining different X-ray fluorescence techniques, a team at BESSY II has now been able to non-invasively measure for the first time where cadmium accumulates exactly in cocoa beans: Mainly in the shell. Further investigations show that the processing of the cocoa beans can have a great influence on the concentration of heavy metals.
