There is striking similarity between properties of the above systems despite different interactions and length scales of inhomogeneities. The fundamental relation between structural inhomogeneities and mechanical and thermodynamic properties is not fully understood because the exchange of knowledge between the solid-state, liquid-matter, soft-matter and biophysical communities is limited. Theoretical and simulation approaches developed by 3 EU MS + 1 AC + 2 TC groups are closely connected or complementary. We use mean-field, liquid-matter, DFT, integral equations, field and collective-variables theories, molecular simulation approaches, and experimental methods of electrochemistry. We will share our experience in constructing/modifying, solving and verifying experimentally models for different complex systems. The new results and theoretical approaches will help in future studies of various inhomogeneous systems. The first work package concerns systems spontaneously forming ordered patterns, from thin films on solid surfaces through particles on interfaces to biological membranes and arid ecosystems. The pattern formation can be exploited in innovative technology. In the second work package we will investigate ionic liquids/ionic-liquid mixtures, especially near charged surfaces and in porous media, and mobile ions in intercalation compounds. Mobile ions and ionic liquids in porous electrodes are potentially important in innovative electrochemistry. EU/TC knowledge transfer will be by joint theoretical, simulation and experimental studies. Open workshops will be organized. Long term visits of young researchers and joint supervision of PhD students are planned.

This project consists of four work packages. The scientific work packages are
The remaining work packages are (WP3) communication, dissemination and transfer of knowledge and (WP4) coordination and management.
The figure below shows how various groups are involved in work packages WP1 and WP2.
Work Package #1: Modeling of self-assembly in systems with competing interactions
To gain fundamental knowledge about universal and specific properties of self-assembling systems, with a special focus on the effects of confinement. In particular, structure, thermodynamic and mechanical properties of various model systems with competing interactions in single compartments with different types of walls and in porous media will be described. Younger researchers will learn advanced theoretical and simulation methods during long-term visits to IPC and CSIC.
Work Package #2: Modeling of systems with dominant electrostatic interactions
Objectives: To extend our knowledge on ionic systems in bulk and at interfaces, specifically in disordered porous media in the regions of large concentration gradients. Various models and confinements will be considered.
Our first workshop was held in Jablonna Palace in Warsaw in 2017. The aim of the workshop was to summarize the recent progress in colloidal and amphiphilic self-assembly and in the room temperature ionic liquids, both in the bulk and in confinement, as well as in mobile ions in intercalation compounds and on solid surfaces. Recent advances in theoretical and simulation methods appropriate for inhomogeneous systems, and in experimental studies of such systems were presented. Outstanding invited theoreticians and experimentalists as well as senior researchers participating in the project delivered review lectures, while younger participants presented posters during two poster sessions. Important open questions were discussed at a round-table closing the workshop. For details see here.
