Moving the Magnet Off-Center: Designing What a Colloid Builds
Group member Jonathan Victoria-Camacho shows that shifting a magnetic particle's dipole away from its center changes which structures it assembles into — loops, worms, chains, and more.
How Particle Size Ratio Reshapes a Magnetic Colloidal Suspension
A bidisperse mixture of magnetic colloids settles into rings, shells, and chains depending on the size ratio between its two species — and the resulting microstructure controls how the suspension magnetization decays in time.
