Capillary Interactions on Fluid Interfaces: Opportunities for Directed Assembly
Nima Sharifi-Mood, Iris B. Liu, Kathleen J. Stebe
A particle placed in soft matter distorts its host and creates an energy landscape. This can occur, for example, for particles in liquid crystals, for particles on lipid bilayers o…
Pair Interaction of Catalytically Active Colloids: From Assembly to Escape
Nima Sharifi-Mood, Ali Mozaffari, Ubaldo Córdova-Figueroa
The dynamics and pair trajectory of two self-propelled colloids are reported. The autonomous motions of the colloids are due to a catalytic chemical reaction taking place asymmetri…
Reply to the Comments on "Curvature capillary migration of microspheres" by P. Galatola and A. Wurger
Nima Sharifi-Mood, Iris B. Liu, Kathleen J. Stebe
We have studied microparticle migration on curved fluid interfaces in experiment and derived an expression for the associated capillary energy for two cases, i.e., pinned conta…
Self-Diffusiophoretic Colloidal Propulsion Near a Solid Boundary
Ali Mozaffari, Nima Sharifi-Mood, Joel Koplik +1
We study the diffusiophoretic self-propulsion of a colloidal catalytic particle due to a surface chemical reaction in a vicinity of a solid wall. Diffusiophoresis is a chemico-mech…
Films of bacteria at interfaces: three stages of behaviour
Liana Vaccari, Daniel Allan, Nima Sharifi-Mood +3
Bacterial attachment to a fluid interface can lead to the formation of a film with physicochemical properties that evolve with time. We study the time evolution of interface (micro…
Curvature Capillary Migration of Microspheres
Nima Sharifi-Mood, Iris B. Liu, Kathleen J. Stebe
We address the question: How does capillarity propel microspheres along curvature gradients? For a particle on a fluid interface, there are two conditions that can apply at the thr…
