Infinite Self‐Propulsion of Circularly On/Discharged Droplets

Advanced Materials
AbstractSelf‐propulsion of droplets in a controlled and long path at a high‐speed is crucial for organic synthesis, pathological diagnosis and programable lab‐on‐a‐chip. To date, extensive efforts have been made to achieve droplet self‐propulsion by asymmetric gradient, yet, existing structural, chemical, or charge density gradients can only last for a

Phoretic Self-Propulsion

Annual Review of Fluid Mechanics, 2017
It is well-known that micro- and nanoparticles can move by phoretic effects in response to externally imposed gradients of scalar quantities such as chemical concentration or electric potential. A class of active colloids can propel themselves through aqueous media by generating local gradients of concentration and electrical potential via surface ...

Enhanced diffusion of pollutants by self-propulsion

Physical Chemistry Chemical Physics, 2011
Current environmental models mostly account for the passive participation of pollutants in their environmental propagation. Here we demonstrate the paradigm-changing concept that pollutants can propagate themselves with a rate that is greater than the rate for standard molecular diffusion by five orders of magnitude.

Self-Propulsion at Low Reynolds Number

Physical Review Letters, 1987
We formulate the problem of self-propulsion at low Reynolds number in terms of a gauge field over the space of shapes. The computation of this field is discussed, and carried out in some examples. We apply our results to determine maximally efficient infinitesimal swimming motions of spheres and circular cylinders.

On the self-propulsion of the euglenoid

Applied Physics Letters, 2014
We characterize the swimming speed of an euglenoid, which is propelled by large shape deformations traveling along its body.
