Journal of Applied Crystallography, EarlyView.We present an improved numerical angle‐dependent absorption correction procedure for line‐collimated small‐ and wide‐angle X‐ray scattering measurements in thin‐walled quartz capillaries. The procedure accounts for the constrained illuminated volume, measured primary beam profiles and capillary‐wall absorption, enabling physically consistent data ...

Journal of Applied Crystallography, EarlyView.We performed grazing‐incidence total X‐ray scattering on an indium tin oxide thin film using a convergent incident beam. This approach enables the acquisition of total scattering profiles up to Q = 21 Å−1, demonstrating the feasibility of laboratory instruments for thin film pair distribution function analysis.Grazing‐incidence total X‐ray scattering ...

From mystery to modulation: the structural story of Rb2[Si2O5]
Acta Crystallographica Section B, EarlyView.The crystal structure of Rb2[Si2O5] has been solved and refined as an incommensurately modulated phase. Each [SiO4] tetrahedron of the phyllosilicate adopts one of two distinct orientations, and the positions of their constituent silicon and oxygen atoms are modeled using a combination of crenel and harmonic positional modulation functions.The crystal ...

The Focal v Control Test: Dealing With P‐hacking Concerns in Meta‐analytical Research
British Journal of Management, EarlyView.ABSTRACT While overwhelming consensus exists that p‐hacking practices trouble management literature, the issue remains largely undiscussed in meta‐analytical research. This is surprising, since meta‐analyses traditionally deal with these types of systematic biases.

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.ABSTRACT Objectives To quantify the discrepancy between anatomical and motor levels in foetuses with open spinal dysraphism and identify prenatal factors associated with this difference. We also examined associations between anatomical level and ultrasound findings. Design Retrospective observational study.

CMAS Attack – A Serious Challenge for Environmental Barrier Coatings
, 2018 Advanced ceramic matrix composites (CMC) promise higher energy efficiency of turbine engines due to substantially higher operation temperatures. The synergistic effect of heat and water-rich exhaust gases, however, is strongly affecting CMC lifetime ...
