Angular Trapping of Spherical Janus Particles [PDF]
Small Methods, 2020 AbstractDeveloping angular trapping methods, which enable optical tweezers to rotate a micronsized bead, is of great importance for studies of biomacromolecules in a wide range of torque‐generation processes. Here a novel controlled angular trapping method based on model composite Janus particles is reported, which consist of two hemispheres made of ...

Screening of heterogeneous surfaces: charge renormalization of Janus particles [PDF]
, 2009 Nonlinear ionic screening theory for heterogeneously charged spheres is developed in terms of a mode-decomposition of the surface charge. A far-field analysis of the resulting electrostatic potential leads to a natural generalization of charge ...

Exact axisymmetric interaction of phoretically active Janus particles
, 2020 We study the axisymmetric interaction of two chemically active Janus particles. By relying on the linearity of the field equations and symmetry arguments, we derive a generic solution for the relative velocity of the particles. We show that regardless of

Controllable Assembly and Application of Janus Smart Nanosheets for Oil Displacement
Frontiers in Chemistry, 2020 Based on the development status of low permeability reservoirs, an intelligent nano-flooding agent is needed to improve the displacement efficiency of reservoirs. Janus particles have the characteristics of small size and strong interfacial activity, and

Electrophoresis of Janus Particles: a Molecular Dynamics simulation study
, 2016 In this work, we use Molecular Dynamics and Lattice-Boltzmann simulations to study the properties of charged Janus particles in an electric field. We show that for relatively small net charge and thick electrostatic diffuse layer mobilities of Janus ...

Hydrodynamic simulations of self-phoretic microswimmers
, 2014 A mesoscopic hydrodynamic model to simulate synthetic self-propelled Janus particles which is thermophoretically or diffusiophoretically driven is here developed.

Phoretic self-propulsion at finite P\'eclet numbers [PDF]
, 2014 Phoretic self-propulsion is a unique example of force- and torque-free motion on small scales. The classical framework describing the flow field around a particle swimming by self-diffusiophoresis neglects the advection of the solute field by the flow ...
