Self-propulsion of a metallic superoleophobic micro-boat [PDF]
Journal of Colloid and Interface Science, 2016 The self-propulsion of a heavy, superoleophobic, metallic micro-boat carrying a droplet of various aqueous alcohol solutions as a fuel tank is reported. The micro boat is driven by the solutocapillary Marangoni flow. The jump in the surface tension owing to the condensation of alcohols on the water surface was established experimentally.

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, 2011Current 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, 1987We 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, 2014We characterize the swimming speed of an euglenoid, which is propelled by large shape deformations traveling along its body.
