TEMUL took a short trip to Forschungszentrum Jülich, Germany, and Johannes Gutenberg University Mainz, Germany, to collect diffraction data on coronene and indomethacin specimens. We used an FEI Titan G2 60-300 HOLO to observe the expected temperature dependent phase change of the coronene crystals and the expected jump as this phase transition occurs. Our colleagues at Bristol grew the indomethacin crystals in a magnetic field, resulting in the growth of nodules along the crystals' surfaces. We carried out automated diffraction tomography on the nodules from the indomethacin crystals to determine whether or not they are crystalline, and if so to determine in which phase they exist. We collected the data on an FEI Tecnai F30.

During the trip, we had the chance to explore both Julich and Mainz. We were spoiled for choice as numerous yet unique bakeries, restaurants and venues populated the streets of both towns, a favourite being Mainz's local tapas bar. The beautiful and ancient Mainzer Dom is the massive cathedral pictured in the gallery. Over 1000 years old, it is truly a testament to German engineering.
