About

Studying the interaction of solvated ions with interfaces has long been a distinguished research topic at the interface of physics, chemistry, and processing technologies. The driving forces in iontronics are not necessarily solely electric, but possibly also osmotic due to an advective fluid flow or diffusive due to ion concentration gradients. These open a plethora of applications in signal-transducing, separation, electrochemical storage, etc. Advances in nanotechnology and computation methods have created a thriving new scientific discipline. In fact, iontronics is expected to play a prominent role in addressing some of the main challenges of the 21st century related to the energy transition, water desalination, circular economy, and green technologies.
IontronicsNL is a network of scientists, mostly based in the Netherlands, with common interest in this topic. The first meeting of the network was organized by Sanli Faez, Esther Alarcon-Llado, and René van Roij at Utrecht University.

IontronicsNL Journal Club

On this website we share our take on the most recent experimental, theoretical, and numerical methods applied to this field and review some of the existing challenges, both in fundamental research as well as in industrial applications.

New Book: Physics of Electrochemical Processes

The past months have been unprecedented for many people around the world, and most were asked to work from home for long periods of time. Though of course we are happy that slowly things are improving, one positive thing did come out of the past months, which is that Maarten Biesheuvel (Wetsus) and Jouke Dykstra (Wageningen University) started writing the book they always wanted to write. The book has now over 300 pages, and is available as a pre-release free of charge from the website www.physicsofelectrochemicalprocesses.com . The book covers many of the topics related to Ionics and Iontronics, including membrane transport (electrodialysis, reverse osmosis) using 1D and 2D models, as well as the DLVW-theory for colloidal interaction, the physics of electrowetting, EDL theories (Frumkin, Donnan, GCS), bio-electrochemical processes, heat effects including electrostatic cooling, and incorporation of acid-base reactions in combined mass transport and reaction modeling. The authors ho

We are happy to announce the second IontronicsNL symposium will be jointly organized by the IontronicsNL and UK-RFB networks.   In this event, we cover the basic science required for understanding the wide range of iontronic processes in redox-flow batteries.   We will also present the latest research results on this rapidly expanding and promising solution for sustainable electrochemical energy storage. The program consists of didactic invited lectures and research presentations from the community focused mostly on recent innovative results for Redox-Flow Batteries. Invited speakers are Marnix Wagemaker (Technical University Delft) Maria Perez-Page (University of Manchester) Jouke Dykstra (Wageningen University & Research) Kathryn Toghill (University of Lancaster) Maarten Voors (Wageningen University & Research) Rathod Suman ( IISC Bangalore ) You can register (free of charge) and/or submit your abstracts here The deadli
