Figure 1: Simulated state diagram illustrating various membrane structures for different Peclet numbers (Pe) characterizing particle propulsion strength and volume fractions (ϕ) of active particles. The three main regimes are tethering (red symbols), fluctuating (blue symbols) and bola/prolate (brown symbols) vesicle shapes. Each dot containing a grid pattern indicates the position of the nearest snapshot within the shape diagram. Simulations mimic a nearly tensionless flaccid vesicle. Copyright: authors

From Soft Active Systems to Synthetic Cells

Scientists from the ETH Zurich and Forschungszentrum Jülich highlight their recent collaborative study on a novel active system of self-propelled particles (SPPs) enclosed in a lipid vesicle, which exhibits dramatic shape changes resembling... (Read more)

Molecular Exchange of Telechelic Polymer Micelles

Telechelic polymers encompass many interesting aspects of soft matter physics – including hierarchical self-assembly, non-Newtonian flow behaviour, and colloidal interactions. Furthermore, they are important as associative thickeners in products used in daily life... (Read more)
