X-ray diffraction imaging with high resolution in all three dimensions is demonstrated, as determined by a quantitative analysis of the reconstructed volume images, and the techniques to be used in atomic-resolution ultrafast imaging at x-ray free-electron laser sources are established.
An assessment of the resolution limitation due to radiation-damage in x-ray diffraction microscopy.
Femtosecond diffractive imaging with a soft-X-ray free-electron laser
Theory predicts1,2,3,4 that, with an ultrashort and extremely bright coherent X-ray pulse, a single diffraction pattern may be recorded from a large macromolecule, a virus or a cell before the sample…

This work represents a previously uncharacterized application of x-ray diffraction microscopy to a specimen of this complexity and provides confidence in the feasibility of the ultimate goal of imaging biological specimens at 10-nm resolution in three dimensions.
Massively parallel X-ray holography
Advances in the development of free-electron lasers offer the realistic prospect of nanoscale imaging on the timescale of atomic motions. We identify X-ray Fourier-transform holography1,2,3 as a…
Femtosecond time-delay X-ray holography
The notion that X-ray flash imaging can be used to achieve high resolution, beyond radiation damage limits for biological samples is supported, and the technique is applied to monitor the dynamics of polystyrene spheres in intense free-electron-laser pulses.

Two refinements of the iterative constraint-based scheme are developed to address the current experimental realities of this imaging technique, which include missing central data and noise.
SHARP: a distributed, GPU-based ptychographic solver
A set of algorithmic and computational methodologies used at the Advanced Light Source, and DOE light sources packaged as a CUDA based software environment named SHARP is introduced, aimed at providing state-of-the-art high-throughput ptychography reconstructions for the coming era of diffraction limited light sources.
Origin and hysteresis of lithium compositional spatiodynamics within battery primary particles
Using an operando x-ray microscopy platform that maps the dynamics of the Li composition and insertion rate in LixFePO4, it is found that nanoscale spatial variations in rate and in composition control the lithiation pathway at the subparticle length scale.
Chemical composition mapping with nanometre resolution by soft X-ray microscopy
A soft X-ray ptychography approach can now image 5-nm-sized objects. Chemical component distributions in the delithiation of LiFePO4 nanoplates — a process relevant for energy storage — links…
