Infrared-induced ultrafast melting of nanostructured platinum films probed by an X-ray free-electron laser
Luca Gelisio, Young Yong Kim, Seon Woo Lim +10
Understanding melting in metals is a hot topic of present research. This may be accomplished by pumping the system with infrared (IR) laser radiation, and probing it with hard X-ra…
Single Alloy Nanoparticle X-Ray Imaging during a Catalytic Reaction
Young Yong Kim, Thomas F. Keller, Tiago J. Goncalves +8
The imaging of active nanoparticles represents a milestone in decoding heterogeneous catalysts dynamics. We report the facet resolved, surface strain state of a single PtRh alloy n…
Gas-induced segregation in Pt-Rh alloy nanoparticles observed by in-situ Bragg coherent diffraction imaging
Tomoya Kawaguchi, Thomas F. Keller, Henning Runge +11
Bimetallic catalysts can undergo segregation or redistribution of the metals driven by oxidizing and reducing environments. Bragg coherent diffraction imaging (BCDI) was used to re…
