The topical issue titled “Charged Species in Bulk and at Interfaces: Interaction, Mobility, Transport, and Regulation” is derived from a series of three CECAM workshops held in 2016, 2018, and 2022. The aim of this issue is to advance our understanding of the complex phenomena surrounding charged species in various environments from a fundamental perspective, with some excursions into practical applications. The issue addresses the characterization of the interactions between a broad variety of charged species as well as of the complex macroscopic behaviour arising from these interactions. Modelling pair interactions between highly charged macromolecules and surfaces resulting from (possibly mobile) charges presents significant challenges; equally challenging is understanding how these interactions govern self-assembly, assembly kinetics, transport in dense systems, response to external electric fields, and regulatory mechanisms. In particular, the transport of charged species, both in bulk and at interfaces, has garnered significant attention due to its fundamental and technological implications. The role of electrostatics and dynamics in biological systems – spanning a wide range of length scales has become a rapidly growing area of research.

The Collection covers the following subjects: computational approaches to lipid-based nucleic acid delivery systems, effective interactions and phase behaviour of protein solutions in the presence of hexamine cobalt (III) chloride, phase transitions of ionic fluids in nanoporous electrodes, effect of repulsive interaction and initial velocity on collective motion process, as well the microfluidic platform for synthesis of polymer and polymer-protein-based protocells. In the fundamental aspect, a hard sphere model for single-file water transport across biological membranes, local electroneutrality breakdown for electrolytes within varying-section nanopores, and Ions and dipoles in electric field: nonlinear polarization and field-dependent chemical reaction are presented.

All articles of this collection are available here and are freely accessible until 30 May 2025. For further information read the Editorial.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
