Abstract

Abstract: The front cover artwork is provided by the groups of Prof. Werner Kunz (University of Regensburg, Germany) and Prof. Juan Manuel García‐Ruiz (Laboratorio de Estudios Cristalográficos, CSIC‐UGR, Spain) as well as Dr. Matthias Kellermeier (BASF SE, Germany). The image shows silica gardens, a peculiar form of tubular precipitates that grow spontaneously in purely inorganic environments. In addition to their striking morphologies, these self‐assembled structures sustain drastic chemical gradients that drive a cascade of coupled diffusion and precipitation processes, which were studied by complementary synchrotron‐based techniques in the present work.

Abstract : "The kinetics of coupled dissolution and precipitation/crystallization processes in self‐assembled silica‐garden structures are elucidated by means of synchrotron X‐ray diffraction and X‐ray absorption spectroscopy. A kinetic model is proposed to describe the relevant reactions on a fundamental physicochemical level…" This and more about the story behind the front cover can be found in the Full Paper at 10.1002/cphc.201600748 .
