Geometry and kinetics determine the microstructure in arrested coalescence of Pickering emulsion droplets
Zhaoyu Xie, Christopher J. Burke, Badel Mbanga +2
An important strategy to stabilize emulsions is to arrest coalescence of the constituent droplets with an opposing rheological force. Colloidal particles adsorbed on the surface of…
The role of curvature anisotropy in the ordering of spheres on an ellipsoid
Christopher J. Burke, Badel L. Mbanga, Zengyi Wei +2
Non-spherical emulsion droplets can be stabilized by densely packed colloidal particles adsorbed at their surface. In order to understand the microstructure of these surface packin…
Simulating defect textures on coalescing nematic shells
Badel L. Mbanga, Kate K. Voorhes, Timothy J. Atherton
Two nematic shells brought in contact coalesce in order to reduce their interfacial tension. This process proceeds through the creation of a liquid neck-like bridge through which t…
Shape and Chirality Transitions in Off-Axis Twist Nematic Elastomer Ribbons
Yoshiki Sawa, Kenji Urayama, Toshikazu Takigawa +5
Using both experiments and finite element simulations, we explore the shape evolution of off-axis nematic elastomer ribbons as a function of temperature. The elastomers are prepare…
Frustrated order on extrinsic geometries
Badel L. Mbanga, Gregory M. Grason, Christian D. Santangelo
We study, analytically and theoretically, defects in a nematically-ordered surface that couple to the extrinsic geometry of a surface. Though the intrinsic geometry tends to confin…
Modeling elastic instabilities in nematic elastomers
Badel L. Mbanga, Fangfu Ye, Jonathan V. Selinger +1
Liquid crystal elastomers are cross-linked polymer networks covalently bonded with liquid crystal mesogens. In the nematic phase, due to strong coupling between mechanical strain a…
