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...
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 ...
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...
The elasticity and flexibility of a human muscle and its contractile properties depend on the presence of reactive oxygen species as well as calcium ions. Mena Michael investigates the calcium responsiveness of muscles both during active contraction and passive stretching. He systematically assessed...
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...
A promising approach to reconstruct human muscle tissue after trauma, necrosis or tumor ablation is the use of cell-free muscle scaffolds processed from previously intact donor organs. Up to now, the required chemical decellularization of tissues is performed mostly manually, with predefined incubat...
