Fast Ptychographic Near-Field Computed Tomography
Sami Wirtensohn, Silja Flenner, Imke Greving +13
Near-field X-ray ptychography enables quantitative three-dimensional imaging with nanometer-scale resolution, but its broader application is limited by long acquisition times - oft…
Imaging aerosolized viruses with an X-ray free-electron laser using single-particle rotational invariants
Tim B. Berberich, Johan Bielecki, Jonas A. Sellberg +12
X-ray free-electron lasers (XFELs) enable diffraction-before-destruction measurements of individual nanosized bioparticles, making it possible to study the structure and dynamics o…
Nanoscale cuticle mass density variations influenced by pigmentation in butterfly wing scales
Deepan Balakrishnan, Anupama Prakash, Benedikt J. Daurer +6
How pigment distribution influences the cuticle density within a microscopic butterfly wing scale, and how both impact each scale's final reflected color, remains unknown. We use p…
Nanoscale Mapping of Magnetic Orientations with Complex X-ray Magnetic Linear Dichroism
Marina Raboni Ferreira, Benedikt J. Daurer, Jeffrey Neethirajan +5
Compensated magnets are of increasing interest for both fundamental research and applications, with their net-zero magnetization leading to ultrafast dynamics and robust order. To…
