On the use of multilayer Laue lenses with X-ray Free Electron Lasers
Mauro Prasciolu, Kevin T. Murray, Nikolay Ivanov +34
Multilayer Laue lenses were used for the first time to focus x-rays from an X-ray Free Electron Laser (XFEL). In an experiment, which was performed at the European XFEL, we demonst…
Influence of Contacts and Applied Voltage on a Structure of a Single GaN Nanowire
Sergey Lazarev, Luca Gelisio, Young Yong Kim +11
Semiconductor nanowires (NWs) have a broad range of applications for nano- and optoelectronics. The strain field of gallium nitride (GaN) NWs could be significantly changed when co…
High spatial coherence and short pulse duration revealed by the Hanbury Brown and Twiss interferometry at the European XFEL
Ruslan Khubbutdinov, Natalia Gerasimova, Giuseppe Mercurio +16
Second-order intensity interferometry was employed to study the spatial and temporal properties of the European X-ray Free-Electron Laser (EuXFEL). Measurements were performed at t…
Classification of diffraction patterns in single particle imaging experiments performed at X-ray free-electron lasers using a convolutional neural network
Alexandr Ignatenko, Dameli Assalauova, Sergey A. Bobkov +4
Single particle imaging (SPI) is a promising method for native structure determination which has undergone a fast progress with the development of X-ray Free-Electron Lasers. Large…
An advanced workflow for single particle imaging with the limited data at an X-ray free-electron laser
Dameli Assalauova, Young Yong Kim, Sergey Bobkov +25
An improved analysis for single particle imaging (SPI) experiments, using the limited data, is presented here. Results are based on a study of bacteriophage PR772 performed at the…
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…
