Накратко на български
Разпределението на йони около сложни структури, като ДНК или колоидни частици, определя как се формират електрическите полета около тях. Това помага за по-доброто разбиране на процесите в тялото и създаването на нови материали и електронни устройства.

Topological Colloidal Double Layers
"In the project Topological Colloidal Double Layers (TCDL) we addressed the problem how a complex geometry or topology can influence the distribution of ions in a wide variety of systems, spanning charge-stabilised colloidal dispersions, but also biological systems such as charged proteins or DNA. We encounter ions everywhere in daily life, where the simplest example is table salt or sodiumchloride, which dissociates in Na+ and Cl-, and other ions that form an integral part of the human body where they are involved in many cellular processes, but also in electronic devices. Our research, is therefore very topical, and leads as a far-reach goal, to a better general understanding of how ions can be used to manipulate electrical charges around large-scale structures (such as proteins), but also in devices. Moreover, new materials can be discovered, that are based on these complex-shaped ion distributions, having immediate societal and technological benefits. The overall objectives of the TCDL project were to find out how ionic charges, that can be as simple as table salt, can influence electrical fields and how they distribute themselves around charged complex-shaped particles (such as colloidal particles or biological charged ""big"" molecules such as DNA). Moreover, this may lead to many novel interesting inter-particle interactions and to the formation of new large-scale structures, such as colloidal crystals, which possible photonic applications."

Цел на проекта
Charged colloidal suspensions consist of charged micron-sized particles dispersed in a solvent with nanometer-sized ions, and they find ample applications in material science, food industry and drug development. The particle charge, together with a diffuse ion cloud that screens this particle charge, is called the electric double layer and it is pivotal in understanding the phase behaviour and interactions in these suspensions. However, no attention has been paid to the topological properties of the electric double layer. While drawing heavily on recent advances in liquid crystalline systems with topologically non-trivial orientational ordering, we propose to explore the topology of electric double layers, which could ultimately lead to enhanced stability of charged colloidal crystals. Specifically, we will focus on particles with topologically non-trivial shapes and explore the coupling between the topological invariants of the particle (such as genus) with the emergent electric double layer, and how this affects interparticle interactions and the phase behaviour. Finally, the goal of this proposal is to obtain a precise control over charged colloidal suspensions that are protected by topological, rather than only energetic binding, opening a fundamental and applied route to a new class of topological soft matter.
