Dichography: Two-frame Ultrafast Imaging from a Single Diffraction Pattern

Linos Hecht, Andre Al Haddad, Björn Bastian +47

We experimentally demonstrate that pairs of time-delayed ultrabright and ultrashort X-ray pulses of two different colors, delivered by modern X-ray Free Electron Lasers, can provid…

Nonlinear phenomena in X-ray fluorescence from single nanoparticles under extreme conditions

Sebastian Cardoch, Tamme Wollweber, Sarodi Jonak Dutta +26

Materials exposed to intense femtosecond X-ray pulses with energies above their K-shell absorption edge can enter an extremely ionized state, which could give rise to nonlinear phe…

Single-particle incoherent diffractive imaging and amplified spontaneous emission in copper nanocubes

Tamme Wollweber, Sarodi Jonak Dutta, Zhou Shen +26

We demonstrate element-specific incoherent diffractive imaging (IDI) of single copper nanocubes using intensity correlations of K fluorescence at a hard X-ray free-electron las…

Direct observation of the exciton polaron by serial femtosecond crystallography on single CsPbBr quantum dots

Zhou Shen, Margarita Samoli, Onur Erdem +28

The outstanding opto-electronic properties of lead halide perovskites have been related to the formation of polarons. Nevertheless, the observation of the atomistic deformation bro…

Impact of gas background on XFEL single-particle imaging

Tong You, Johan Bielecki, Filipe R. N. C. Maia

Single-particle imaging (SPI) using X-ray free-electron Lasers (XFELs) offers the potential to determine protein structures at high spatial and temporal resolutions without the nee…
