Probing three-dimensional mesoscopic interfacial structures in a single view using multibeam X-ray coherent surface scattering and holography imaging

open access: yesNature Communications, 2023
Visualizing surface-supported and buried planar mesoscale structures, such as nanoelectronics, ultrathin-film quantum dots, photovoltaics, and heterogeneous catalysts, often requires high-resolution X-ray imaging and scattering.

Pump-probe X-ray holographic imaging of laser-induced cavitation bubbles with femtosecond FEL pulses

open access: yesNature Communications, 2021
Cavitation bubbles show many nonlinear characteristics of liquid and gas phase. Here the authors demonstrate coherent diffractive imaging of cavitation bubble using infrared pump and XFEL probe and discuss the formation and evolution of the bubbles.

The X-ray Outbursts of Be/X-ray Transients [PDF]

open access: yesInternational Astronomical Union Colloquium, 2000
AbstractWe present a new scenario for the behaviour of Be/X-ray binaries based on long-term multiwavelength monitoring and the decretion disc model. The circumstellar discs of the primaries are truncated because of the tidal and resonant effect of the neutron star. The geometry of the systems and the value of viscosity determine the presence or absence

Vimentin intermediate filaments stabilize dynamic microtubules by direct interactions

open access: yesNature Communications, 2021
The tasks of the cytoskeleton depend on the fine-tuned interplay between the three filamentous components: actin filaments, microtubules, and intermediate filaments.

Superconducting undulator activities at the European X-ray Free-Electron Laser Facility

open access: yesFrontiers in Physics, 2023
For more than 5 years, superconducting undulators (SCUs) have been successfully delivering X-rays in storage rings. The European X-Ray Free-Electron Laser Facility (XFEL) plans to demonstrate the operation of SCUs in X-ray free-electron lasers (FELs ...

Nondestructive cellular-level 3D observation of mouse kidney using laboratory-based X-ray microscopy with paraffin-mediated contrast enhancement

open access: yesScientific Reports, 2022
For three-dimensional observation of unstained bio-specimens using X-ray microscopy with computed tomography (CT), one main problem has been low contrast in X-ray absorption.

In situ X-ray area detector flat-field correction at an operating photon energy without flat illumination

open access: yesJournal of Synchrotron Radiation, 2023
Flat-field calibration of X-ray area detectors is a challenge due to the inability to generate an X-ray flat-field at the selected photon energy the beamline operates at, which has a strong influence on the measurement behavior of the detector.

Radionuclide diagnosis of ureteric function in patients with stages I-IV cancer of the cervix uteri

open access: yesОпухоли женской репродуктивной системы, 2014
The experience with serial renal scintigraphy demonstrated its high informative value and safety in evaluating the severity of intrarenal urine outflow disorders; however, failure to make an objective assessment of ureteral patency considerably limits ...
