Journal ArticleDOI
Fabrication by Laser Irradiation in a Continuous Flow Jet of Carbon Quantum Dots for Fluorescence Imaging
Carlos Doñate-Buendía,Rafael Torres-Mendieta,Alexander Pyatenko,Eva Falomir,Mercedes Fernández-Alonso,Gladys Mínguez-Vega +5 more
TL;DR: The integrated photostability of the CQDs internalized in in vitro cells is measured and it remains almost constant during at least 2 h, revealing their outstanding performance as fluorescent labels.
Journal ArticleDOI
Oxide dispersion-strengthened alloys generated by laser metal deposition of laser-generated nanoparticle-metal powder composites
Carlos Doñate-Buendía,Felix Frömel,Markus Benjamin Wilms,René Streubel,Jochen Tenkamp,Tim Hupfeld,Milen Nachev,Emine Gökce,Andreas Weisheit,Stephan Barcikowski,Frank Walther,Johannes Henrich Schleifenbaum,Bilal Gökce +12 more
TL;DR: In this article, a new method is proposed for producing nanoparticle-metal composite powders for laser additive manufacturing of oxide-dispersion strengthened (ODS) alloys, and the structural properties of manufactured ODS alloys were analyzed, and their hardness, remnant porosity, and temperature-dependent compression behavior were characterized to study the effect of the composition and size of the nanoparticles on the structural and mechanical properties.
Journal ArticleDOI
Microstructure formation and mechanical properties of ODS steels built by laser additive manufacturing of nanoparticle coated iron-chromium powders
Carlos Doñate-Buendía,Philipp Kürnsteiner,Felix Stern,Markus Benjamin Wilms,René Streubel,Ihsan Murat Kusoglu,Jochen Tenkamp,Enrico Bruder,N. Pirch,Stephan Barcikowski,Karsten Durst,Johannes Henrich Schleifenbaum,Frank Walther,Baptiste Gault,Baptiste Gault,Bilal Gökce +15 more
TL;DR: In this article, the microstructure, nanoparticle evolution, and mechanical properties of ODS steels prepared by dielectrophoretic controlled adsorption of 0.08 wt% laser-synthesized yttrium oxide (Y2O3) on an iron-chromium ferritic steel powder (PM2000) were evaluated by electron backscatter diffraction, scanning electron microscopy-energy-dispersive X-ray spectroscopy, and atom probe tomography.
Journal ArticleDOI
Depositing laser-generated nanoparticles on powders for additive manufacturing of oxide dispersed strengthened alloy parts via laser metal deposition
René Streubel,Markus Benjamin Wilms,Carlos Doñate-Buendía,Andreas Weisheit,Stephan Barcikowski,Johannes Henrich Schleifenbaum,Bilal Gökce +6 more
TL;DR: In this article, the adsorption of pulsed laser-dispersed nanoparticles onto metal powders in aqueous solution without using any binders or surfactants is presented.
