Abstract Induced‐charge electroosmosis (ICEO) offers a practical approach to drive microscale flows by application of AC electric fields across polarizable surfaces, enabling diverse functions including microfluidic pumping, active cargo transport, and biosensing. While ICEO along pristine surfaces is well‐understood, applications often require surface modifications that affect in manner poorly understood. Here, this study introduces dielectrophoretic (DEP) polarizability measurement, DPM,...
Cellulose esters (CEs) are promising biodegradable substitutes for traditional petroleum-based plastic materials. Research on structure–property relationships of CEs is necessary to evaluate their suitability industrial applications such as food packaging. with different side-chain lengths were synthesized and studied. Their thermal moisture barrier properties characterized. triheptanoate (CTH) was proved have an optimal (WVTR = 0.31 g·mil/day/in.2) used blend...
We report direct measurements of potential energy landscapes for different shaped colloidal particles interacting with nonuniform AC electric fields. Epoxy particle shapes investigated include disks, ellipses, squares, rectangles, and rhombuses, which are all part the superelliptical prism shape class chosen to systematically vary anisotropy corner features. The measurement configuration consists noninteracting single sedimented onto microscope slides within fields between parallel coplanar...
We report a model to predict equilibrium density profiles for different shaped colloids in two-dimensional liquid, nematic, and crystal states nonuniform external fields. The predictions are validated against Monte Carlo simulations optical microscopy experiments circular, square, elliptical, rectangular colloidal particles AC electric fields between parallel electrodes. the densities of all is based on balance local quasi-2D osmotic pressure compressive force due induced dipole-field...
