In Situ X‐Ray Diffraction Study of a Microwave‐Based Hydrothermal Synthesis of Mayenite Ca12Al14O33

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Microwave‐assisted hydrothermal synthesis enables rapid transformation of aluminium‐ and calcium‐hydroxide into mayenite with high surface area. Optimised synthesis conditions comprise a microwave step at 80°C for 5 min followed by calcination at 800°C. The reactions during calcination were studied via in situ XRD measurements.

Uncovering hidden bias in neutron diffraction residual strain measurements

Journal of Applied Crystallography, EarlyView.
This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...

Microsecond X‐ray reflectometry

Journal of Applied Crystallography, EarlyView.
X‐ray reflectometry is accelerated to 213 µs net exposure time using galvanometer scanning, which enables unprecedented temporal resolution for studying dynamic thin‐film processes.We accelerate synchrotron X‐ray reflectometry (XRR) by more than an order of magnitude and demonstrate the acquisition of full reflectivity curves within 213 µs over a qz ...
