Abstract: Abstract The diffractive imaging-based encryption (DIBE) is vulnerable to chosen plaintext attack (CPA) because of the direct relation between plaintext and ciphertext. In this paper, a HYBRID method, which consists of combining simplified diffractive imaging-based… read more here.

DOI: 10.1038/s41467-019-10448-x
Abstract: X-ray free electron lasers (XFELs) create new possibilities for structural studies of biological objects that extend beyond what is possible with synchrotron radiation. Serial femtosecond crystallography has allowed high-resolution structures to be determined from micro-meter… read more here.

DOI: 10.1103/physrevlett.119.053401
Abstract: Established x-ray diffraction methods allow for high-resolution structure determination of crystals, crystallized protein structures, or even single molecules. While these techniques rely on coherent scattering, incoherent processes like fluorescence emission-often the predominant scattering mechanism-are generally… read more here.

DOI: 10.1126/sciadv.abf1386
Abstract: Phase coexistence during a solid-to-solid transition in a quantum material is measured using x-ray coherent diffractive imaging. Solid-state systems can host a variety of thermodynamic phases that can be controlled with magnetic fields, strain, or… read more here.

DOI: 10.1364/oe.25.010757
Abstract: We demonstrate a modal approach to simultaneous recovery of a sample transmission function and coherence properties of an illuminating X-ray beam that works from a single measurement. The approach based on coherence diffractive imaging, does… read more here.
