The advent of X-ray free-electron lasers (FELs) promises to eliminate the resolution limitation imposed on imaging of biological materials by radiation damage 1. Owing to the extreme brevity and high ...
Reconstructing the phase of a field from intensity measurements is an old and ubiquitous challenge, known as the phase retrieval problem 1,2,3. It has found numerous applications spanning from ...
X-ray diffraction studies conducted at high pressure with a beryllium pressure vessel show that compression parallel to the c-axis of CaCO$_{3}$-I (calcite), as the phase boundary of CaCO$_{3}$-II ...
