Dynamics of a microswimmer near a curved wall: guided and trapped locomotions
Nima Sharifi-Mood, Pablo G. Díaz-Hyland, Ubaldo M. Córdova-Figueroa
We propose a combined analytical-numerical strategy to predict the dynamics and trajectory of a microswimmer next to a curved spherical obstacle. The microswimmer is actuated by a…
Capillary Assembly of Colloids: Interactions on Planar and Curved Interfaces
Iris B. Liu, Nima Sharifi-Mood, Kathleen J. Stebe
In directed assembly, small building clocks are assembled into an organized structures under the influence of guiding fields. Capillary interactions provide a versatile route for s…
Elastocapillary driven assembly of particles at free-standing smectic-A films
Mohamed Amine Gharbi, Daniel A. Beller, Nima Sharifi-Mood +4
Colloidal particles at complex fluid interfaces and within films assemble to form ordered structures with high degrees of symmetry via interactions that include capillarity, elasti…
Curvature capillary repulsion
Iris B. Liu, Giulia Bigazzi, Nima Sharifi-Mood +2
Directed assembly of colloids is an exciting field in materials science to form structures with new symmetries and responses. Fluid interfaces have been widely exploited to make de…
Self-Propelled Colloidal Particle Near a Planar Wall: A Brownian Dynamics Study
Ali Mozaffari, Nima Sharifi-Mood, Joel Koplik +1
Miniaturized, self-propelled locomotors use chemo-mechanical transduction mechanisms to convert fuel in the environment to autonomous motion. Recent experimental and theoretical st…
Curvature-driven migration of colloids on lipid bilayers
Ningwei Li, Nima Sharifi-Mood, Fuquan Tu +4
Colloids and proteins alike can bind to lipid bilayers and move laterally in these two-dimensional fluids. Inspired by proteins that generate membrane curvature, sense the underlyi…
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…
Capillary migration of microdisks on curved interfaces
Lu Yao, Nima Sharifi-Mood, Iris B. Liu +1
The capillary energy landscape for particles on curved fluid interfaces is strongly influenced by the particle wetting conditions. Contact line pinning has now been widely reported…
