Self-Healing Small-Scale Swimmers
Emil Karshalev, Cristian Silva-Lopez, Kyle Chan +6
Herein, self-healing small-scale swimmers capable of autonomous propulsion and on-the-fly structural recovery are described. The new strategy instantaneously restores the functiona…
Extrapolation theory for Stokes flow past a deformed sphere
Amir Nourhani, Paul E. Lammert
We formulate a method for computing Stokes flow past a highly deformed sphere with arbitrarily defined surface velocity. The fundamental ingredient is an explicit extrapolation ope…
Spiral diffusion of rotating self-propellers with stochastic perturbation
Amir Nourhani, Stephen J. Ebbens, John G. Gibbs +1
Translationally diffusive behavior arising from the combination of orientational diffusion and powered motion at microscopic scales is a known phenomenon, but the peculiarities of…
Bypassing slip velocity: rotational and translational velocities of autophoretic colloids in terms of surface flux
Paul E. Lammert, Vincent H. Crespi, Amir Nourhani
A standard approach to propulsion velocities of autophoretic colloids with thin interaction layers uses a reciprocity relation applied to the slip velocity. But the surface flux (c…
Efficacy of self-phoretic colloids and microswimmers
Amir Nourhani, Paul E. Lammert
Within a unified formulation, encompassing self-electrophoresis, self-diffusiophoresis, and self-thermophoresis, we provide a simple integral kernel transforming the relevant surfa…
