Crystallization behavior of ion beam sputtered HfO2 thin films and its effect on the laser-induced damage threshold

open access: yesJournal of the European Optical Society-Rapid Publications, 2021
In this work, we present our results about the thermal crystallization of ion beam sputtered hafnia on 0001 SiO2 substrates and its effect on the laser-induced damage threshold (LIDT).

Microsecond hydrodynamic interactions in dense colloidal dispersions probed at the European XFEL

open access: yesIUCrJ, 2021
Many soft-matter systems are composed of macromolecules or nanoparticles suspended in water. The characteristic times at intrinsic length scales of a few nanometres fall therefore in the microsecond and sub-microsecond time regimes.

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

Origin of the scatter in the X-ray luminosity of early-type galaxies observed with ROSAT [PDF]

open access: yes, 2000
Statistical properties of X-ray luminosity and temperature are studied for 52 early-type galaxies based on the ROSAT PSPC data. All of the X-ray luminous galaxies show largely extended emission with a radius of a few times of 10$r_e$, while X-ray faint ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Adversarial robustness improvement for X-ray bone segmentation using synthetic data created from computed tomography scans

open access: yesScientific Reports
Deep learning-based image analysis offers great potential in clinical practice. However, it faces mainly two challenges: scarcity of large-scale annotated clinical data for training and susceptibility to adversarial data in inference.

MHz X-ray photon correlation spectroscopy using an acoustic levitator at the European XFEL

open access: yesJournal of Synchrotron Radiation
The structural and dynamical properties of soft-matter systems play an important role in crystallization and nucleation theory. Despite their significance, the dynamical properties are still poorly understood because of experimental constraints and the ...

Adsorption of oleic acid on magnetite facets

open access: yesCommunications Chemistry, 2022
Metal oxide nanoparticles functionalized by organic molecules are important building blocks for nanocomposites. Here, the authors study the adsorption of oleic acid on magnetite (001) and (111) surfaces experimentally by SXRD, LEED, FT-IRRAS and XRR, and

Diffuse X-ray scattering from polished silicon: application of the distorted wave Born approximation

open access: yesJournal of Synchrotron Radiation, 2022
Measured diffuse X-ray scattering data for a `smooth' as well as for a `rough' silicon sample were fit to theoretical expressions within the distorted wave Born approximation (DWBA).
