Fabrication of micrometer-sized drops as templates for particles

Mathias Steinacher

Drops are omnipresent in our daily life for example in the form of rain drops or as oil drops in a salad dressing. On a technological basis, drops can be used to conduct chemical or biological reactions. These drops often serve as templates to produce mate ...

Refinement for single-nanoparticle structure determination from low-quality single-shot coherent diffraction data

Christoph Bostedt, Christophe Nicolas

With the emergence of X-ray free-electron lasers, it is possible to investigate the structure of nanoscale samples by employing coherent diffractive imaging in the X-ray spectral regime. In this work, we developed a refinement method for structure reconstr ...

Multispectroscopic Study of Single Xe Clusters Using XFEL Pulses

Christoph Bostedt, Christophe Nicolas

X-ray free-electron lasers (XFELs) deliver ultrashort coherent laser pulses in the X-ray spectral regime, enabling novel investigations into the structure of individual nanoscale samples. In this work, we demonstrate how single-shot small-angle X-ray scatt ...

Using the excellent performances of a SACLA (RIKEN/HARIMA, Japan) X-ray free electron laser (X-FEL), coherent diffraction imaging (CDI) was used to detect individual liposome particles in water, with or without inserted doxorubicin nanorods. This was possi ...

2018

Here we present a new approach to diffraction imaging of amyloid fibrils, combining a freestanding graphene support and single nanofocused X-ray pulses of femtosecond duration from an X-ray free-electron laser. Due to the very low background scattering fro ...

Generation and measurement of sub-micrometer relativistic electron beams

Rasmus Ischebeck, Eugenio Ferrari, Christian David

The generation of low-emittance electron beams has received significant interest in recent years. Driven by the requirements of X-ray-free electron lasers, the emittance of photocathode injectors has been reduced significantly, with corresponding increase ...
