Pathway selection by an active droplet

Abstract

We report the movement of an active 1-pentanol drop within a closed Y-shaped channel subjected to geometrical and chemical asymmetry. A Y-shaped channel was configured with an angle of 120◦...

Can self-propelled objects escape from compression stimulation?

“…Based on the experimental results and related reports, 19–32 we discuss the mechanism of escape from C in to C out for two types of self-propelled objects: CPs and MCPs. Here, the time required for N out to reach 4 as the equilibrium condition is defined as the relaxation time, t e .…”

“…Alternatively, the repulsive force between CPs makes them difficult to crowd together. 20,23,26,32 Fig. 4 and 5 suggest that the difference in surface tension between C in and C out enhances the escape of CPs from C in to C out because CPs move in the direction of higher surface tension.…”

“…4 and 5 suggest that the difference in surface tension between C in and C out enhances the escape of CPs from C in to C out because CPs move in the direction of higher surface tension. 23,26,30–32…”
