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 extern...
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 ...
Last year, Florian Bauer published on his work on in-situ spectroscopy of soot formation. He continues his efforts in his recent publication on the “Characterisation of the transition type in optical band gap analysis of in-flame soot”. By monitoring the flame at two different positions, he uses abs...
Bastian Lehnert works on the optimization of 3D imaging of transient fuel sprays. His measurement technique is called ‘diffuse back illumination extinction imaging’. Simply said, the fuel spray is placed between an LED panel with specific characteristics and a High-Speed-Camera which records the lig...
Earlier this year, Dominic Bartels published his work on in-situ modification of case-hardening steel. He continues these efforts in his recent work “PBF-LB/M of Low-Alloyed Steels: Bainite-like Microstructures despite High Cooling Rates”. It focusses on the processing of this group of steels using ...
Last year, Alexander Wittmann introduced a laser with a wavelength of 1.94 µm for the consolidation of thermoplastic polymer coatings on metallic substrates. Since light of this wavelength is absorbed in the polymers themselves, light-absorbing additives are not required for the coating process. Thi...
Sebastian-Paul Kopp works on a new technique for powder deposition in laser-based additive manufacturing. Similar to the principle of a laser printer, a light-induced charge pattern on a photoconductive plate allows a spatially resolved distribution of polymer powder on the build platform. This redu...
Last year, Tim Russwurm showed that “Flame Luminesce in an Optically Accessible Engine with an Active Fuelled Pre-Chamber Ignition System” is a suitable detection technique for ignition and combustion processes. By monitoring the inside of an engine cylinder with a high speed camera he gained insigh...
To monitor the material’s topography in laser machining, optical coherence tomography (OCT) is a promising imaging technique, which goes beyond the state-of-the-art methods like laser triangulation. In his latest publication, Thomas Will identified relevant Features for image processing of OCT image...
Accurate knowledge of thermophysical properties of working fluids in chemical and energy engineering is necessary for the proper design or optimization of apparatuses and processes. This aspect is linked to the subject area Thermophysical Property Research dealt within the research activities of the...
