High Efficiency Electrokinetic Energy Conversion via Superhydrophobic
Abstract
A key strength of Stonybrook s technical approach is the combination of theoretical/computational modeling with advanced fabrication and characterization techniques. Specific tasks are as follows: (1) Modeling: combination of continuum-based models, molecular dynamics, and mesoscopic simulations to determine electrokinetic coupling coefficients for different nanostructure morphologies. (2) Optimization: system-level analysis (parametric continuation) and stability analysis to determine optimal combinations of channel dimensions, electrolyte concentration, and pressure differentials for which the energy conversion efficiency is enhanced. (3) Manufacturing: fabrication of nanostructured surfaces and integration in single-channel micro/nanofluidic devices; using block-copolymer assisted lithography, photolithography or combination thereof. (4) Characterization: determination of slip lengths and electrostatic potentials via environmental CP-AFM, forced imbibition using SAXS and other synchrotron-based X-ray techniques, andmacroscopic wettability measurements. Measurement of streaming currents/potentials for the designed micro/nanofludic devices under a range of relevant conditions (e.g., pressure differentials, temperature).
