Multiscale Rheo-Optical and Scattering Signatures of Deformation-Induced Anisotropy in Aqueous Cellulose Nanocrystal Suspensions under Large-Amplitude Oscillatory Shear

Abstract Aqueous surface-charged cellulose nanocrystal (CNC) suspensions exhibit concentration-dependent viscosity growth, gelation, and deformation-induced anisotropy, but the concentration and strain-amplitude ranges over which these responses emerge are not necessarily the sam...

Guest-host approach to reduce driving voltages in electro optic liquid crystal devices

We describe a simple guest-host approach allowing the reduction of driving voltages in liquid crystal (LC) electro optic devices via the increase of the effective dielectric anisotropy. This is achieved by doping the nematic LC host by molecules possessing high dipole moments. Po...
