Acousto-microfluidic Control of Liquid Crystals
Gustavo A. Vasquez-Montoya, Tadej Emersic, Noe Atzin +7
The optical properties of liquid crystals serve as the basis for display, diagnostic, and sensing technologies. Such properties are generally controlled by relying on electric fiel…
Dynamics of active defects on the anisotropic surface of an ellipsoidal droplet
Martina Clairand, Ali Mozaffari, Jérôme Hardoüin +6
Cells are fundamental building blocks of living organisms displaying an array of shapes, morphologies, and textures that encode specific functions and physical behaviors. Elucidati…
Generation and propagation of solitary waves in nematic liquid crystals
Xingzhou Tang, Ali Mozaffari, Noe Atzin +3
Solitons in nematic liquid crystals offer intriguing opportunities for transport and sensing in microfluidic systems. Little is known about the elementary conditions that are neede…
A minimal model of solitons in nematic liquid crystals
Noe Atzin, Ali Mozaffari, Xingzhou Tang +3
Solitons in liquid crystals have generated considerable interest. Several hypotheses of varying complexity have been advanced to explain how they emerge, and a consensus has not em…
Transformation between elastic dipoles, quadrupoles, octupoles and hexadecapoles driven by surfactant self-assembly in nematic emulsion
Bohdan Senyuk, Ali Mozaffari, Kevin Crust +3
Emulsions comprising isotropic fluid drops within a nematic host are of interest for applications ranging from biodetection to smart windows, which rely on changes of molecular ali…
Defect Spirograph: Dynamical Behavior of Defects in Spatially Patterned Active Nematics
Ali Mozaffari, Rui Zhang, Noe Atzin +1
Topological defects in active liquid crystals can be confined by introducing gradients of activity. Here, we examine the dynamical behavior of two defects confined by a sharp gradi…
Structuring Stress for Active Materials Control
Rui Zhang, Steven A. Redford, Paul V. Ruijgrok +8
Active materials are capable of converting free energy into mechanical work to produce autonomous motion, and exhibit striking collective dynamics that biology relies on for essent…
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…
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…
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…
