Bipolar ion-exchange membranes are a class of charged polymers that enable precise control of ionic fluxes and local pH, making them potentially valuable for many energy and environmental applications. This Review focuses on the fundamental physics underpinning their operation across multiple scales, from nanomorphology to integration within devices such as in bipolar-membrane electrodialysis (BPM-ED).
To mark the inaugural issue of Nature Chemical Engineering, we asked a collection of scientists working in different branches of chemical engineering to share their perspectives on the challenges and opportunities that lie ahead for their respective fields.
This Perspective discusses electrochemically mediated carbon dioxide capture systems, which can offer lower energetics than standard thermal methods, with modular scalability. New integrated configurations can further reduce costs and improve unit productivity, while further engineering of existing cell designs will enable more rapid implementation.
