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.

D‐stroi – a uniaxial load frame for X‐ray diffraction and imaging
Journal of Synchrotron Radiation, EarlyView.A remote miniature load frame for X‐ray diffraction and imaging applications is presented. The load frame has been assessed for mechanical stability and suitability for various synchrotron X‐ray‐based techniques.We present a remotely controlled miniature load frame for in situ tensile deformation of millimetre‐sized metal samples in synchrotron X‐ray ...

Deciphering unusually large modulations in two related organic hydroxy channel structures
Acta Crystallographica Section B, EarlyView.Two related organic hydroxy‐channel compounds are shown to have unusually large structural modulations.The incommensurately modulated structures of two related organic hydroxy‐channel compounds [(R)‐1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐(octan‐2‐yl)urea, 1; 1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐octylurea, 2] have been determined and compared to the structure of a ...

Acta Crystallographica Section D, EarlyView.Monte Carlo simulations of neutron protein diffraction experiments provide useful data that models neutrons interacting with instrument components, as well as the crystal diffraction itself. These data can be applied to instrument development, such as the commissioning of the NMX Macromolecular Diffractometer at ESS.Monte Carlo neutron ray‐tracing ...
