Sebastian-Paul Kopp: Advanced 3D printing with charged particles
Last year, Sebastian-Paul Kopp introduced a new technique for powder deposition in laser-based additive manufacturing of polymer structures. He transferred charged polymer particles to the build platform using a locally charged photoconductive plate. This enables high powder efficiency and the printing of individually structured shapes. In his recent publication, “Enabling triboelectric charging as a powder […]Last year, Sebastian-Paul Kopp introduced a new technique for powder deposition in laser-based additive manufacturing of polymer structures.

Markus Labus and Peter Lang: Imaging temperature fields in aerosols
Last year, Markus Labus and Peter Lang published on their new setup for optical temperature measurements in flames and aerosols. They continued their efforts and now were able to demonstrate calibration-free imaging of temperature fields in flames containing indium particles. The fluorescent light emission of indium is dependent on its temperature. Thus, by tuning the […]

Lisa Ackermann: Smoothing laser patterns for materials processing
Last year, Lisa Ackermann already published on beam shaping of high-energy lasers for materials processing by using spatial light modulators (SLMs). As she pointed out, a drawback is the presence of speckle noise, which overlays the shaped intensity structure and drastically reduces the beam quality. It arises from interference of the laser waves and cannot […]

Yogeshwar Nath Mishra & Florian Bauer: The world’s fastest 2D imaging of flames
A timeframe of 80 picoseconds is extremely short. In this interval, light rays – able to travel from the earth to the moon in about one second – go a distance of 2.5 millimeters only. In a joint project of Caltech, Gothenburg University, and FAU, Yogeshwar Nath Mishra and Florian Bauer now realized the world’s […]

Jonas Bollmann: Improving the provision of hydrogen from LOHC fluids
As previously described, liquid organic hydrogen carrier (LOHC) fluids may play a major role in future energy storing, as they are able to reversibly store and release hydrogen molecules. This release, namely the dehydrogenation of the LOHC, is an endothermic reaction, which means it requires external heat energy. In a novel approach, Jonas Bollmann uses […]

Jonas Bollmann: Optical access to temperature distributions in LOHC fluids
To safely store hydrogen as a future energy carrier, liquid organic hydrogen carrier (LOHC) systems are a highly promising option. In the presence of a catalyst, these organic molecules are able to repeatedly absorb and release hydrogen molecules through chemical reactions depending on the pressure and temperature. Thus, it is important to know the temperature […]
