The quiescent X-ray emission of three transient X-ray pulsars [PDF]

, 2002
We report on BeppoSAX and Chandra observations of three Hard X-Ray Transients in quiescence containing fast spinning (P10 higher, testifying that the quiescent emission mechanism is different.

Multi-beam X-ray ptychography using coded probes for rapid non-destructive high resolution imaging of extended samples

Scientific Reports, 2022
Imaging large areas of a sample non-destructively and with high resolution is of great interest for both science and industry. For scanning coherent X-ray diffraction microscopy, i. e., ptychography, the achievable scan area at a given spatial resolution

X-ray mirrors with sub-nanometre figure errors obtained by differential deposition of thin WSi2 films

Journal of Synchrotron Radiation, 2023
Differential deposition by DC magnetron sputtering was applied to correct for figure errors of X-ray mirrors to be deployed on low-emittance synchrotron beamlines. During the deposition process, the mirrors were moved in front of a beam-defining aperture

X-ray sources as tracers of the large-scale structure in the Universe

, 2000
We review the current status of studies of large-scale structure in the X-ray Universe. After motivating the use X-rays for cosmological purposes, we discuss the various approaches used on different angular scales including X-ray background multipoles ...

Microstructural evolution during sintering of copper particles studied by laboratory diffraction contrast tomography (LabDCT)

Scientific Reports, 2017
Pressureless sintering of loose or compacted granular bodies at elevated temperature occurs by a combination of particle rearrangement, rotation, local deformation and diffusion, and grain growth.

X-ray observations of Be/X-ray binaries in the SMC

, 2003
(shortened) Fifteen Be/X-ray binaries and candidates in the SMC were observed serendipitously with the EPIC instruments of XMM-Newton during two observations of SNR 0047-73.5 and SNR 0103-72.6 in October 2000.

Evaluation of methods for 3D imaging and analysis of vascularisation in biopreparations

Current Directions in Biomedical Engineering, 2022
Motivation: Within the field of bio-implants one topic deals with the in-vitro production of 3D tissues from cell cultures. A major challenge in the cultivation of biopreparations is the imitation of the vascular system with its surrounding tissue ...

The anabolic steroid stanozolol is a potent inhibitor of human MutT homolog 1

FEBS Letters, EarlyView.
MutT homolog 1 (MTH1) is a member of the NUDIX superfamily of enzymes and is an anticancer drug target. We show that stanozolol (Stz), an anabolic steroid, is an unexpected nanomolar inhibitor of MTH1. The X‐ray crystal structure of the human MTH1–Stz complex reveals a unique binding scaffold that could be utilized for future inhibitor development ...

X-ray irradiation of the winds in binaries with massive components

, 2015
Binaries with hot massive components are strong X-ray sources. Besides the intrinsic X-ray emission of individual binary members originating in their winds, X-ray emission stems from the accretion on the compact companion or from wind collision.
