Pattern Formation in Catalytic Colloidal Microswimmers

Objective

Self-propelled particles such as bacteria, or 'Janus colloids' partially coated with catalyst, consume energy from their environment and convert it into systematic motion. Interacting ensembles of these particles compose so-called active matter which is intrinsically driven out of thermodynamic equilibrium. This allows for a rich and unusual phenomenology that includes condensation and phase separation in systems with purely repulsive interactions; giant density fluctuations; and various types of self-organized structure formation whose origin lies beyond the equilibrium principle of entropy maximization (free energy minimization). In PFCCMS we propose a novel theoretical study of activity-induced pattern formation with active colloids, addressing the interplay of an anisotropic production of chemicals at the colloidal surfaces and a chemotactic coupling of the particles to the resulting chemical gradients. Careful inclusion of noise within our coarse grained descriptions will enrich the emerging self-organized spatiotemporal structures with phenomena based on nucleation and topological defects. Our findings are expected to inform design principles for activity-induced self-organization of soft materials; we also plan to link them with the physics of gene-surfing and the spatiotemporal organization of bacterial colonies.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

MSCA-IF-EF-ST - Standard EF

Coordinator

THE UNIVERSITY OF EDINBURGH
Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
