In recent years, powder- and beam-based additive manufacturing processes have successfully established in the fabrication of highly individualized, geometrically complex components. Generating functional components for series production places the highest demands on the robustness of the processes, ...
Without knowing core parameters of a process, there is not much guidance for optimizing the process itself or its outcome. This also applies to the synthesis of functional nanoparticles. In recent years and decades, the importance and utilization of such nanoparticles in scientific, medical and indu...
The laser is a universal tool in materials processing. Focusing a high-power laser to a single spot allows various applications like welding and laser-based additive manufacturing. Heating and consequent melting of the material mainly drives these processes in which the laser beam acts as a heat sou...
After her study on material science, Marion Merklein received a PhD in mechanical engineering. Her PhD thesis is about laser forming of aluminum alloys and the influence of the laser forming process on the materials‘ microstructure and mechanical characteristics.
In 2006 she finished her habilita...
Andreas Erdmann studied physics at the Friedrich Schiller University in Jena, where he received a PhD for his work on “Nonlinear optical phase conjugation in photorefractive Bi12GeO20 crystals and applications in optical metrology”. From 1990 to 1995 he worked as a post-doc at the University of Osna...
Spray flame synthesis is a powerful tool for the generation of functionalized nanoparticles, yet sophisticated measurement techniques are required to investigate droplet evolution and nanoparticle formation in such a complex process. In his recent publication, “In Situ Determination of Droplet and N...
Laser-based additive manufacturing enables the realization of steel-based products in sophisticated new shapes. Dominic Bartels published on the “In situ modification of case-hardening steel 16MnCr5 by C and WC addition by means of powder bed fusion with laser beam of metals (PBF-LB/M)”. He investig...
For the first time, Manuel Kerscher determined the “Viscosity and Surface Tension of Benzene at Saturation Conditions from Surface Light Scattering”. His results consolidate the capability of surface light scattering as an accurate absolute measurement technique for the simultaneous determination of...
Thermoplastic foams are used in a broad variety of applications. The resulting foam properties are governed by the nucleation and bubble growth behavior, which are both strongly influenced by the thermophysical properties of the blowing-agent-loaded polymer melt. Especially knowledge on diffusion co...
The recent publication of Lisa Ackermann deals with “Uniform and efficient beam shaping for high-energy lasers”. By setting two spatial light modulators in a proper arrangement, she realized a setup that enables tailored light fields even for high-energy pulsed lasers. Thus, she was able to create a...
