Self-Assembly Of Magnetic Janus Colloids
Authors: Jonathan A. Victoria-Camacho, Wilmer A. Martinez-Valle
Anisotropic potentials in Janus colloids provide additional freedom to control particle aggregation into structures of different sizes and morphologies. In this work, we perform Brownian dynamics simulations of a dilute suspension of magnetic spherical Janus colloids with their magnetic dipole moments shifted radially and parallel toward the surface of the particle to gain valuable microstructural insight. Properties such as the mean cluster size, orientational ordering, and nucleation and growth are examined dynamically.
Breakage Of Amphiphilic Janus Particles Aggregates Under Shear Flow
Authors: Joysy R. Tafur-Ushinahua, Birendra A. Magar-Puwar
We study the assembly of single-patch colloidal Janus particles under steady shear flow via Brownian dynamics simulations. In the absence of flow, by varying the Janus patch size and the range and strength of the anisotropic interaction potential, Janus colloids form different aggregates such as micelles, wormlike clusters, vesicles, and lamellae.
Fabrication Of Magnetic Janus Particles With Adjustable Magnetic Properties And Self-Propulsion
Authors: Jonathan A. Victoria-Camacho, Wilmer A. Martinez-Valle
This project aims to develop a novel technique for fabricating active-magnetic radially shifted Janus particles, previously simulated for their unique properties. This research aims to enhance the production of these distinctive active-magnetic Janus particles, with the potential to find applications in diverse fields such as micro- and nanorobotics, precision drug delivery, and colloidal science.
