Journal ArticleDOI
Size Quenching during Laser Synthesis of Colloids Happens Already in the Vapor Phase of the Cavitation Bubble
Alexander Letzel,Bilal Gökce,Philipp Wagener,Shyjumon Ibrahimkutty,Andreas Menzel,Anton Plech,Stephan Barcikowski +6 more
TL;DR: In this paper, the size quenching reaction between nanoparticles and ions starts already during cavitation bubble confinement or if these reactions are subjected to the liquid phase, by probing the cavitation bubbles interior by means of small-angle X-ray scattering (SAXS).
Journal ArticleDOI
Ligand-free Gold Nanoparticles as a Reference Material for Kinetic Modelling of Catalytic Reduction of 4-Nitrophenol
Sasa Gu,Julian Kaiser,Galina Marzun,Andreas Ott,Yan Lu,Matthias Ballauff,Alessio Zaccone,Stephan Barcikowski,Philipp Wagener +8 more
TL;DR: In this paper, the catalytic activity of bare gold nanoparticles prepared by laser ablation in liquid without any stabilizers or ligands was analyzed, and the results showed that the nanoparticles were among the most active catalysts for the 4-nitrophenol reduction by sodium borohydride.
Journal ArticleDOI
Magnetic Alloy Nanoparticles from Laser Ablation in Cyclopentanone and Their Embedding into a Photoresist
TL;DR: The applicability of femtosecond laser ablation for the generation of colloidal metal nanoparticles has been investigated using the example of Ni(48)Fe(52) and Sm(2)Co(17) ablation in cyclopentanone and proved the preservation of the stoichiometry of the target in Ni-Fe nanoparticles but not in Sm-Co.
Book ChapterDOI
Toxicity of gold nanoparticles on somatic and reproductive cells.
Ulrike Taylor,Annette Barchanski,Wiebke Garrels,Sabine Klein,Wilfried A. Kues,Stephan Barcikowski,Detlef Rath +6 more
TL;DR: The biocompatibility of gold nanoparticles depends on a range of particle specific aspects as well as the choice of target tissue, and further clarification of such matters are subject to ongoing research.
Journal ArticleDOI
Influence of processing time on nanoparticle generation during picosecond-pulsed fundamental and second harmonic laser ablation of metals in tetrahydrofuran
TL;DR: In this paper, the influence of fundamental and second harmonic wavelength on ablation efficiency and nanoparticle properties was studied during picosecond laser ablation of silver, zinc, and magnesium in polymer-doped tetrahydrofuran.
