Dynamic site‐interconversion reduces the induction period of methanol‐to‐olefin conversion

open access: yesAIChE Journal, EarlyView.
Abstract Reaction–diffusion coupling across the catalyst pore, grain, pellet, and reactor bed has been studied using a particle‐resolved transient microkinetic model applied to temperature‐programmed desorption and step‐response studies of methanol and dimethyl ether conversion over ZSM‐5 catalysts, respectively.

Bimodal Ionic Conduction through Polymer Films due to Nano Confinement

open access: yesAngewandte Chemie, EarlyView.
This minireview revisits the phenomenon of nano‐confined ion conduction through polymer films. Ions diffuse through polymer films in two distinct modes depending on the nano‐structure and free space for the passage of hydrated or partially hydrated ions.

Li21Ge8P3S34: New Lithium Superionic Conductor with Unprecedented Structural Type

open access: yesAngewandte Chemie, EarlyView.
The discovery of high ion‐conductive inorganic crystal structures remains a challenge in facilitating the development of all‐solid‐state batteries. Ionic conductors reported to date have predominantly been limited to well‐known crystal structures. In this work, we report a new, unprecedented crystalline structure, Li21Ge8P3S34, which demonstrates high ...

Aza‐Diphosphazenanes: Inorganic Cyclohexane‐like Connectors with Stereochemically Tunable Exit Vectors for Molecular and Macromolecular Chemistry

open access: yesAngewandte Chemie, EarlyView.
New aza‐diphosphinanes have been prepared and a model has been developed to explain their cis/trans isomerization. Two‐fold oxidation leads to new aza‐diphosphazenanes as robust inorganic connectors with selectable stereochemistry. Polycondensation reactions results in the first inorganic cyclo‐linear polyphosphazenes which have high‐molecular weights ...
