Preparation Laboratory
The preparation laboratory of the Department of Physics prepares samples for use in physics experiments and measurements. The range of services includes the processing of single crystals and semiconductors by sawing, grinding, lapping and polishing of planar surfaces, the X-rayographic orientation of single crystals, the production of coatings in high vacuum such as contact layers, antireflection coatings, electrodes and the like, as well as electroplated gold plating. In addition, the preparation laboratory develops new preparation methods and serves as a warehouse for consumables. Also offered are the production of deionized and distilled water, as well as consulting and disposal of sample material.

![3D visualisation of human neuronal tissue reconstructed by multi-scale X-ray phase contrast tomography. Neuronal cell nuclei are shown in yellow for the granule neurons in the dentate gyrus region of the hippocampus. Blood vessels are shown in red. By changing the X-ray optical magnification in the multi-scale recordings, one can zoom into regions-of-interest (red ovals). In these scans the resolution is high enough to resolve sub-structures of the nucleus, associated with different DNA packing regimes.
