In-situ composition analysis during laser powder bed fusion of Nd-Fe-based feedstock using machine-integrated optical emission spectroscopy
Autor: Anna Rosa Ziefuss, Philipp Gabriel, René Streubel, Milen Nachev, Bernd Sures, Florian Eibl, Stephan Barcikowski
Publikováno v: Materials & Design, Vol 244, Iss , Pp 113211- (2024)
Powder bed fusion of metals using a laser beam (PBF-LB/M) is a widely used additive manufacturing (AM) technique that enables the material-efficient fabrication of complex geometries in metallic parts. However, achieving high-quality parts with desir

Speciation in nanosecond laser ablation of zinc in water
Autor: Stefan Reich, Yannis Klügl, Anna Ziefuss, René Streubel, Jörg Göttlicher, Anton Plech
Publikováno v: Science China Physics, Mechanics & Astronomy, 65 (7), Art.Nr. 274205
In situ experimental methods have been applied to resolve mass flow and chemical speciation in the pulsed laser ablation of zinc in water. The chemical speciation has been resolved by time-resolved μ-X-ray absorption spectroscopy and mapped onto the

Autor: Stephan Barcikowski, Christof Schulz, René Streubel, Erwan Bertin, Thomas Vinnay, Galina Marzun, Adrian Münzer, Hartmut Wiggers, Sven Reichenberger
Publikováno v: Applied Surface Science. :1181-1186
Ligand-free platinum nanoparticles were prepared by pulsed laser ablation in liquids (PLAL) and employed as a benchmarking catalyst to evaluate the durability of a new gas-phase synthesized graphene support in oxygen reduction conditions. Raman measu

Synthesis of gold, platinum, and gold-platinum alloy nanoparticle colloids with high-power megahertz-repetition-rate lasers : The importance of the beam guidance method
Autor: Friedrich Waag, René Streubel, Stephan Barcikowski, Bilal Gökce
Nanoparticles of noble metals and their alloys are of particular interest for biomedicine and catalysis applications. The method of laser ablation of bulk metals in liquids gives facile access to such particles as high-purity colloids and is already

In situ speciation and spatial mapping of Zn products during pulsed laser ablation in liquids (PLAL) by combined synchrotron methods
Autor: Alexander Letzel, Olivier Mathon, Bilal Gökce, Anton Plech, René Streubel, Stephan Barcikowski, Anna Rosa Ziefuss, Andreas Menzel, Sakura Pascarelli, Jörg Göttlicher, Marcus Zuber, Tilo Baumbach, Stefan Reich
Publikováno v: Nanoscale, 12 (26), 14011-14020
'Nanoscale ', vol: 12, pages: 14011-14020 (2020)
Pulsed laser ablation in liquids is a hierarchical multi-step process to produce pure inorganic nanoparticle colloids. Controlling this process is hampered by the partial understanding of individual steps and structure formation. In situ X-ray method
