Multi-modal impedance and X-ray characterization enables simultaneous detection of bulk and interfacial crystallization A multi-modal platform enabling simultaneous impedance spectroscopy and X-ray scattering is presented. When applied to zeolite crystallization, four-electrode impedance measurements reliably track bul...

Running in situ isothermal crystallisation studies of #zeolites (165°C, 40 bar) at BM01@SNBL @esrf.fr, simultaneously monitoring conductivity, T and P in situ, using our newest sample environment.

Tracking crystallization processes can be cumbersome, specifically when samples react with the sample environment. In a special setup, enabling in situ 2- and 4-electrode impedance measurements, crystallization effects at electrodes or in the bulk can clearly be distinguished, while at the same time enabling structural characterization with X-ray diffraction.

The paper about our combined X-ray and impedance characterization cell is out!

Ewoud made his PhD at NMRCoRe, working on parahydrogen hyperpolarization. He then joined Sami Jannin @ CRMN, Lyon for a successful postdoc, developing dissolution DNP. Highly looking forward to having Ewoud back at NMRCoRe and to enable the exciting new science he is planning.

Congratulations to all new @FWOVlaanderen postdoctoral fellows, and especially to Dr. Ewoud Van Eeckhaute. He was awarded a senior postdoctoral fellowship to rejoin NMRCoRe.

Chemistry of Materials In inorganic systems, zeolites crystalize with a framework maximizing the topological cation occupancy. This explains how inorganic cations can template a multitude of different zeolite topologies. View the article.
