2616. Tilting Transition in a Liquid Crystalline Polymer Brush

The equilibrium phase behaviour of a semi-dilute, liquid crystalline (LC) polymer brush is investigated, using self-consistent field theory with wormlike chains and implicit solvent. For good solvent conditions, the isotropic interactions favor a stretched brush while the anisotropic LC interactions favor collapsing into a high-density nematic state. By allowing the nematic director to orient...

2741. Direct Measurement of the Dynamic Modulus of Gellan Gum Micro-Capsules

Prof. John Frostad (University of British Columbia)

Invited Speaker / Conférencier(ère) invité(e)

Micro-capsules are increasingly being studied as models for cells, as drug delivery vehicles, and even as devices for enhanced oil recovery form porous substrates. As such, understanding of their mechanical properties is critical for rational design and optimal performance. Here we describe experiments using a Cantilevered-Capillary Force Apparatus to probe the dynamic (or complex) modulus of...

2425. Electrokinetic transport in porous media

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

Electrokinetic transport phenomena, predominantly realized in charged polymeric and porous media, offer possibilities for applications in nanofluidic systems, energy harvesting and biosensing. In this work, we present a theoretical and numerical study of nonlinear coupling between wall deformation and the flows of water and ions in a charged, deformable nanochannel. The classical...
