Self-assembly of surfactant molecules drives changes of liquid crystal molecular alignment around droplets in nematic emulsions. 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 alignment structures around the drops in response to chemical, thermal, electric, and other stimuli. We show that absorption or desorption of trace amounts of common surfactants can drive…

Design and Preparation of Nematic Colloidal Particles.

Colloidal systems are abundant in technology, in biomedical settings, and in our daily life. The so-called "colloidal atoms" paradigm exploits interparticle interactions to self-assemble colloidal

Theory of elastic interaction between axially symmetric 3D skyrmions in confined chiral nematic liquid crystals and in skyrmion bags

We study axially symmetrical 3D skyrmionic particles (torons, hopfions) in a thin homeotropic cell filled with a cholesteric liquid crystal. In this case, the contribution of the chirality term on

Unsteady Separated Stagnation-Point Flow Past a Moving Plate with Suction Effect in Hybrid Nanofluid

Previous research has shown that incorporating stagnation-point flow in diverse manufacturing industries is beneficial due to its importance in thermal potency. Consequently, this research




Inverse nematic emulsions, in which surfactant-coated water droplets are dispersed in a nematic host fluid, have distinctive properties that set them apart from dispersions of two isotropic fluids or

Hexadecapolar colloids

The physical underpinnings of formation of colloidal elastic hexadecapoles are uncovered and the ensuing bonding inaccessible to elastic dipoles, quadrupoles and other nematic colloids studied previously are described.

Nematic liquid crystal boojums with handles on colloidal handlebodies

Robust generation of boojums is demonstrated by controlling surface topology of colloidal particles that impose tangential boundary conditions for the alignment of LC molecules and discusses how this interplay between the topologies of colloids surfaces and boojum may lead to controlled self-assembly of colloid particles in nematic and paranematic hosts, which, in turn, may enable reconfigurable topological composites.

Physics of colloidal dispersions in nematic liquid crystals

Edge pinning and transformation of defect lines induced by faceted colloidal rings in nematic liquid crystals.

How transformation of bulk and surface defect lines induced by faceted colloids can enrich the diversity of elasticity-mediated colloidal interactions is discussed and how these findings may impinge on prospects of their controlled reconfigurable self-assembly in nematic hosts is discussed.

Colloidal inclusions in liquid crystals: Phase separation mechanisms and some dynamical aspects

This article reviews recent findings on the formation of ordered colloidal structures from bulk demixing in liquid crystalline materials. In contrast to classical phase separations, which lead to

Lattice Boltzmann simulation of asymmetric flow in nematic liquid crystals with finite anchoring.

This work considers the hydrodynamics of a nematic LC in a hybrid cell, where opposite walls have conflicting anchoring boundary conditions, and employs a 3D lattice Boltzmann method to simulate the time-dependent flow patterns that can arise.

Colloidal interactions and unusual crystallization versus de-mixing of elastic multipoles formed by gold mesoflowers

The gold microparticles can induce elastic multipoles of different symmetries when dispersed in a nematic liquid crystal as building blocks for various crystals, showing that gold mesoflowers may serve as a designer toolkit for engineering colloidal interaction and self-assembly, potentially exceeding that in atomic and molecular systems.

Power-Law Forces Between Particles in a Nematic

Abstract Macroscopic particles of size a immersed in liquid crystalline solvents (e.g. polystyrene spheres in a lyotropic nematic) will exert long-range forces on each other by distorting the

Microscope textures of nematic droplets in polymer dispersed liquid crystals

Computer simulations are made of polarizing microscope textures of supramicron‐sized nematic droplets with director configurations which commonly occur in polymer and other dispersions. The
