Fast algorithms for nonlinear and constrained phase retrieval in near-field X-ray holography based on Tikhonov regularization
Simon Huhn, Leon Merten Lohse, Jens Lucht +1
Based on phase retrieval, lensless coherent imaging and in particular holography offers quantitative phase and amplitude images. This is of particular importance for spectral range…
Regularized Newton Methods for X-ray Phase Contrast and General Imaging Problems
Simon Maretzke, Matthias Bartels, Martin Krenkel +2
Like many other advanced imaging methods, x-ray phase contrast imaging and tomography require mathematical inversion of the observed data to obtain real-space information. While an…
Interaction of Alamethicin Pores in DMPC Bilayers
Doru Constantin, Guillaume Brotons, Ansgar Jarre +2
We have investigated the x-ray scattering signal of highly aligned multilayers of the zwitterionic lipid 1,2-dimyristoyl-sn-glycero-3-phosphatidylcholine containing pores formed by…
Biomimetic membranes of lipid-peptide model systems prepared on solid support
Chenghao Li, Doru Constantin, Tim Salditt
The structure of membrane-active peptides and their interaction with lipid bilayers can be studied in oriented lipid membranes deposited on solid substrates. Such systems are desir…
Dynamics of bulk fluctuations in a lamellar phase studied by coherent x-ray scattering
Doru Constantin, Guillaume Brotons, Tim Salditt +2
Using x-ray photon correlation spectroscopy, we studied the layer fluctuations in the lamellar phase of an ionic lyotropic system. We measured the relaxation rate of in-plane (undu…
Grain rotation and lattice deformation during photoinduced chemical reactions revealed by in-situ X-ray nanodiffraction
Zhifeng Huang, Matthias Bartels, Rui Xu +8
In-situ X-ray diffraction (XRD) and transmission electron microscopy (TEM) have been used to investigate many physical science phenomena, ranging from phase transitions, chemical r…
