Defining the trade routes of ancient civilizations is of particular importance when no written sources are available. The fragility, rarity, and preciousness of ancient gold work require the use of nondestructive techniques like X-ray fluorescene at BAMline at BESSY II.

Air pollution is one of the many issues in large cities that influence the quality of life and the environment. ClearfLo (Clean Air for London) is a large, multidisciplinary and multi-institutional field project with the goal of refining the knowledge of processes and interactions in the
atmospheric boundary layer that influence the weather, the atmospheric chemistry and air quality in this megacity.
An international group of researchers from Germany and France have investigated structural changes of industrially relevant ferroelectric materials on a time scale down to 50 microseconds. Ferroelectrics find a multitude of applications as actuators, sensors, or data storage devices.
In 2010, researchers from European XFEL and Deutsches Elektronen-Synchrotron predicted a dramatic improvement in the already remarkable features of X-ray free-electron lasers by placing a special crystal into the path of the radiation while rerouting the electron beam around the crystal. In 2012, their colleagues from the Linac Coherent Light Source (LCLS) in the US and the Technological Institute for Superhard and Novel Carbon Materials in Russia implemented the proposed setting and confirmed superior beam quality.
