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 …

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 …

Coherent diffractive imaging (CDI) and scanning transmission x-ray microscopy (STXM) are
two popular microscopy techniques that have evolved quite independently. CDI promises to …

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 …

Small-angle scattering (SAS) of x-rays and neutrons is a fundamental tool in the study of
biological macromolecules. The major advantage of the method lies in its ability to provide …

Abstract Theory predicts,,, 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 …

We demonstrate a hard-x-ray microscope that does not use a lens and is not limited to a
small field of view or an object of finite size. The method does not suffer any of the physical …

Iterative projection algorithms are successfully being used as a substitute of lenses to
recombine, numerically rather than optically, light scattered by illuminated objects. Images …

Analytical tools that have spatial resolution at the nanometre scale are indispensable for the
life and physical sciences. It is desirable that these tools also permit elemental and chemical …

X-ray sources are develo** rapidly and their coherent output is growing correspondingly.
The increased coherent flux from modern X-ray sources is being matched with an …
