Penn Researchers Demonstrate How to Control Liquid Crystal Patterns(图)
Penn Researchers Liquid Crystal Patterns
2017/11/23
When Lisa Tran set out to investigate patterns in liquid crystals, she didn’t know what to expect. When she first looked through the microscope, she saw dancing iridescent spheres with fingerprint-lik...
Penn Physicists Discover Why Drying Liquid Crystal Drops Leave Unusual “Coffee Rings”(图)
Penn Physicists Drying Liquid Crystal Drops Coffee Rings
2017/7/21
In previous papers, University of Pennsylvania physicists investigated the “coffee ring effect,” the ring-shaped stain of particles left after drops of coffee evaporate. In one paper, they learned how...
Liquid crystal turns water droplets into 'gemstones,' Penn materials research shows(图)
Liquid crystal gemstones
2014/3/17
Liquid crystals are remarkable materials that combine the optical properties of crystalline solids with the flow properties of liquids, characteristics that come together to enable the displays found ...
A Newton-Penalty Method for A Simplified Liquid Crystal Model
harmonic maps nonlinear constraint Newton's method regularized func-tional saddle points
2012/8/10
In this paper we are concerned with the computation of a liquid crystal model de痭ed
by a simpli痚d Oseen-Frank energy functional and a (sphere) nonlinear constraint. A
particular case of this model d...
Modeling the Mechanisms of the Photomechanical Response of a Nematic Liquid Crystal Elastomer
Modeling Nematic Liquid Crystal Elastomer
2011/9/2
Recent studies of azo-dye doped liquid crystal elastomers show a strong photomechanical response.We report on models that predict experimental results that suggest photothermal heating is the dominant...
Depth Profile of Optically Recorded Patterns in Light-Sensitive Liquid Crystal Elastomers
Depth Profile Optically Recorded Patterns Light-Sensitive Liquid Crystal Elastomers
2011/8/11
Abstract: We investigated nonlinear absorption and photobleaching processes in a liquid crystal elastomer (LCE) doped with light-sensitive azobenzene moiety. A conventional one-dimensional holographic...
Ultrathin optical switch based on a liquid crystal/silver nanoparticles mixture as a tunable indefinite medium
Ultrathin optical switch liquid crystal silver nanoparticles tunable indefinite medium
2011/8/2
Abstract: We predict that a liquid crystal/silver nanoparticles mixture can be designed so that, in a frequency range, its effective ordinary and extraordinary permittivities have real parts of differ...
Fluctuation-induced Non-equilibrium Transition in a Liquid-Crystal Metastable System
fluctuation dissipation metastable configuration Langevin equation
2010/11/22
The research herein studies the Langevin dynamics allowing for an exchange of energy between
liquid crystals and the thermal environment. This dynamics leads to fluctuation and dissipation
behaviors...
Finite dimensional reduction and convergence to equilibrium for incompressible Smectic-A liquid crystal flows
Finite dimensional reduction incompressible Smectic-A liquid crystal flows
2010/11/8
We consider a hydrodynamic system that models the Smectic-A liquid crystal flow. The model consists of the Navier-Stokes equation for the fluid velocity coupled with a fourth-order equation for the la...
Colloidal particles in liquid crystal films and at interfaces
colloids confinement interfaces elastic theory computer simulations
2010/11/18
This mini-review discusses the recent contribution of theoretical and computational physics as well as experimental efforts to the understanding of the behavior of colloidal particles in confined geom...
Orientability and energy minimization in liquid crystal models
Orientability energy minimization liquid crystal models
2010/12/6
Uniaxial nematic liquid crystals are modelled in the Oseen-Frank theory through a unit vector field n. This theory has the apparent drawback that it does not respect the head-to-tail symmetry in which...
