Thermophoresis of colloids in nematic liquid crystal

Autor: Qi-Huo Wei, Andrew Konya, Jakub Kolacz, Robin L. B. Selinger

Publikováno v: Soft matter. 16(8)

Thermophoresis, or the directional motion of colloidal particles in liquids driven by a temperature gradient, is of both fundamental interest and practical use. In this work we explore the thermophoresis of colloids suspended in nematic liquid crysta

Gradient-driven diffusion and pattern formation in crowded mixtures

Autor: Andrew Konya, Brandy Grove, Prithviraj Nandigrami, Robin L. B. Selinger

Publikováno v: Physical Review E. 95

Gradient-driven diffusion in crowded, multicomponent mixtures is a topic of high interest because of its role in biological processes such as transport in cell membranes. In partially phase-separated solutions, gradient-driven diffusion affects micro

Nature, 546(7660):636 (546), 632-636. Nature Publishing Group

Oscillating materials that adapt their shapes in response to external stimuli are of interest for emerging applications in medicine and robotics. For example, liquid-crystal networks can be programmed to undergo stimulus-induced deformations in vario

Modeling Defects, Shape Evolution, and Programmed Auto-origami in Liquid Crystal Elastomers

Autor: Andrew Konya, Robin L. B. Selinger, Vianney Gimenez-Pinto

Publikováno v: Frontiers in Materials, Vol 3 (2016)

Liquid crystal elastomers represent a novel class of programmable shape-transforming materials whose shape change trajectory is encoded in the material's nematic director field. Using three-dimensional nonlinear finite element elastodynamics simulati

Monte Carlo Studies of the XY Model on Two-Dimensional Curved Surfaces

Autor: Jonathan V. Selinger, Alex Travesset, Robin L. B. Selinger, Andrew Konya

Publikováno v: The Journal of Physical Chemistry B. 115:13989-13993

To explore the interaction between topological defects and curvature in materials with orientational order, we perform Monte Carlo studies of the two-dimensional XY model on the surface of curved substrates. Each curved surface is patterned with a ra

Brownian Motion of Arbitrarily Shaped Particles in Two-Dimensions

Autor: Jonathan V. Selinger, Kai Sun, Andrew Konya, Feng Wang, Ayan Chakrabarty, Qi-Huo Wei

We implement microfabricated boomerang particles with unequal arm lengths as a model for nonsymmetric particles and study their Brownian motion in a quasi-two-dimensional geometry by using high-precision single-particle motion tracking. We show that

Brownian Motion of Boomerang Colloidal Particles

Autor: Andrew Konya, Feng Wang, Kai Sun, Ayan Chakrabarty, Jonathan V. Selinger, Qi-Huo Wei

We investigate the Brownian motion of boomerang colloidal particles confined between two glass plates. Our experimental observations show that the mean displacements are biased towards the center of hydrodynamic stress (CoH), and that the mean-square
