The problem of phase retrieval, ie, the recovery of a function given the magnitude of its
Fourier transform, arises in various fields of science and engineering, including electron …

X-ray crystallography has been central to the development of many fields of science over the
past century. It has now matured to a point that as long as good-quality crystals are …

Very high resolution X-ray imaging has been the subject of considerable research over the
past few decades. However, the spatial resolution of these methods is limited by the …

We present a technique called white-light diffraction tomography (WDT) for imaging
microscopic transparent objects such as live unlabelled cells. The approach extends …

Transmission electron microscopy is a powerful imaging tool that has found broad
application in materials science, nanoscience and biology,,. With the introduction of …

X-ray-based analytics are routinely applied in many fields, including physics, chemistry,
materials science, and engineering. The full potential of such techniques in the life sciences …

Cell density shows very little variation within a given cell type. For example, in humans
variability in cell density among cells of a given cell type is 100 times smaller than variation …

Tomography has made a revolutionary impact on the physical, biological and medical
sciences. The mathematical foundation of tomography is to reconstruct a three-dimensional …

There exists a conspicuous gap of knowledge about the organization of life at mesoscopic
levels. Ultra-fast coherent diffractive imaging with X-ray free-electron lasers can probe …

Emerging X-ray free-electron lasers with femtosecond pulse duration enable single-shot
snapshot imaging almost free from sample damage by outrunning major radiation damage …
