We show that sterically interacting self-propelled disks in the presence of random pinning substrates exhibit transitions among a variety of different states. My present main interest is the interface-dominated dynamics of complex liquids and soft matter, i. · A transition from a pin-free phase separated state to a homogeneous state can be induced by increasing the substrate strength. Langm () Living tissues undergo wetting transitions: On a surface, they can either form a droplet-like cell aggregate or spread as a monolayer of migrating cells.

Olson Reichhardt J. Ricard Alert and Jaume Casademunt. · Dewetting transition - a concept borrowed from fluid dewetting and spreading transitions for active matter mechanics - is a physiological process that takes place inside the hydrophobic pores of ion channels.

In this work, we manipulate this adhesion to induce dewetting and formation of bilayer membranes by using a mixture of a more volatile good solvent and a less volatile poor solvent for the diblock copolymers.

In particular, we analyse (i) an on–off ratchet with a constant lateral force resulting in a dewetting–spreading cycle, (ii) a ratchet switching between two shifted potentials that shows a transition between oscillating and sliding drops, and (iii) a flashing external force ratchet. Here, we utilise the rapid early development of Drosophila melanogaster embryos to uncover the.

1−12 The transport of a water drop on a solid is a complex process owing to the nature of contact between the solid and the liquid. Transitions XTRActive lenses even activate behind the car windshield. Thus, the blue lines correspond to thermodynamically defined wetting transition lines, satisfying S = S c. · If the contact angle is zero, the droplet dewetting and spreading transitions for active matter spreads across the surface, a situation referred to as complete wetting. The most commonly known phase changes are those six between solids, dewetting and spreading transitions for active matter liquids, and gasses. · Analogous to a liquid droplet, the balance of cell-cell and cell-substrate adhesion energy governs whether an aggregate will spread or form a 3D droplet. A variety of experimental techniques and biophysical dewetting and spreading transitions for active matter models have exploited these analogies allowing the quantitative characterization of the mechanical properties of model tissues. .

force resulting in a dewetting–spreading cycle, (ii) a ratchet switching between two dewetting and spreading transitions for active matter shifted potentials that shows a transition between oscillating and sliding drops, and (iii) a flashing external force ratchet. This transient phenomenon causes a metastable dewetting and spreading transitions for active matter state that forbids water molecules to cross microscopic receptor cavities. · Introduction. This transition can be viewed as an active matter version of a wetting-dewetting or spreading transition, 27 where the active particles spread out to cover the dewetting and spreading transitions for active matter surface when the pinning is strong. · Actually, we have confirmed no hysteresis; dewetting (complete-to-partial wetting) and spreading (partial-to-complete wetting) occur at almost the dewetting and spreading transitions for active matter same temperature and vapor pressure (Movies S5 and S6). dewetting and spreading transitions for active matter This transition dewetting and spreading transitions for active matter can be viewed as an active matter version of a wetting-dewetting or spreading transition 27, where the active particles spread out to cover the surface when the pinning is strong. This includes active (biologically inspired) media. To minimize the total free energy of the system, these drops coarsen over time until one single drop remains.
