Front Cover: Functional Rhythmic Chemical Systems Governed by pH-Driven Kinetic Feedback (ChemSystemsChem 2/2023)

Abstract

The Front Cover depicts an hourglass and suggests a pH variation over time. The temporal variation of pH caused by hydrogen or hydroxide ion autocatalytic reactions provides a convenient way to control the state or drive the mechanical motion of coupled pH-sensitive physicochemical systems. More information can be found in the Review by Brigitta Dúzs, István Lagzi and István Szalai.
