General Description:

Anisotropic potentials in Janus particles provide additional freedom to control particle aggregation into clusters with different sizes and  morphologies. In our research group, we study the process of aggregation and breakage in a dilute suspension of magnetic Janus colloids with their magnetic dipole moments shifted radially towards the surface of the particle using a simulation method called Brownian dynamics. Using these simulations, a catalog of the different dynamic formations of magnetic colloids depending on the magnetic interaction parameter λ and the dipole displacement s is found, thereby obtaining a phase diagram that represents the regions of different types of aggregations. We continue our study obtaining the critical values of the Péclet number Pe (a dimensionless group that represents the competition between propulsion and Brownian motion) for which it promotes or stops the growth or formation of aggregates.
