Hard x-ray scanning microscopy with coherent radiation: Beyond the resolution of conventional x-ray microscopes
A. Schropp,Robert Hoppe,Jens Patommel,D. Samberg,Frank Seiboth,Sandra Stephan,G. Wellenreuther,Gerald Falkenberg,Christian G. Schroer +8 more
TL;DR: In this paper, the authors demonstrate x-ray scanning coherent diffraction microscopy (ptychography) with 10nm spatial resolution, clearly exceeding the resolution limits of conventional hard X-ray microscopy, showing that the spatial resolution in a ptychogram is dependent on the shape (structure factor) of a feature and can vary for different features in the object.

TL;DR: In this paper, the authors presented an experimental realization of these optics made of silicon and demonstrate that they indeed focus 20'keV x rays to a 18.4'nm focus with a numerical aperture of 1.73'9''×'10−3 that clearly exceeds the critical angle of total reflection.

TL;DR: A laboratory based high resolution x-ray radiograph was developed for the investigation of solidification dynamics in alloys and high quality image sequences of the solidification process were obtained with high resolution in time and space.

TL;DR: The phase contrast imaging instrument at the Matter in Extreme Conditions (MEC) endstation of the Linac Coherent Light Source as mentioned in this paper can image phenomena with a spatial resolution of a few hundreds of nanometers and reveal the atomic structure through X-ray diffraction, with a temporal resolution better than 100 fs.

TL;DR: Hard X-ray microscopy with synchrotron radiation has been extensively studied in the literature as mentioned in this paper, with a focus on scanning microscopy of hard X-rays with refractive lenses.
