Tuning cholesteric cellulose nanocrystal self-assembly in spherical confinement via salt and sonication
Diogo Vieira Saraiva, Anne Meike Hogeweg, Lisa Tran
Cellulose nanocrystals (CNCs) self-assemble into cholesteric liquid crystals that produce structural color upon solvent removal. Although most studies examine this process in plana…
Controlling viscosity to engineer focal conic domains in photonic cellulose nanocrystal films
Diogo V. Saraiva, Lotte Polling, Ivo R. Vermaire +3
Cellulose nanocrystals (CNCs) form cholesteric architectures that can have color specific reflectivity and enable sustainable photonic films. However, achieving uniform color, supp…
Shaping boundaries to control and transport topological defects in colloidal nematic liquid crystals
Gerardo Campos-Villalobos, André F. V. Matias, Ethan I. L. Jull +2
Anisotropic rod-like particles form liquid crystalline phases with varying degrees of orientational and translational order. When confined geometrically, these phases can give rise…
Flexible, photonic films of surfactant-functionalized cellulose nanocrystals for pressure and humidity sensing
Diogo V. Saraiva, Steven N. Remiëns, Ethan I. L. Jull +2
Most paints contain pigments that absorb light and fade over time. A robust alternative can be found in nature, where structural coloration arises from the interference of light wi…
Curvature directed anchoring and defect structure of colloidal smectic liquid crystals in confinement
Ethan I. L. Jull, Gerardo Campos-Villalobos, Qianjing Tang +2
Rod-like objects at high packing fractions can form smectic phases, where the rods break rotational and translational symmetry by forming lamellae. Smectic defects thereby include…
