The new class of micro/nanofluidic diodes with an ideal perm-selective membrane were demonstrated at a wide concentration range from 10−5 M to 3 M. Moreover, the rectification factor was actively controlled by adjusting the external convective flows.
Elucidating the mechanism of electrokinetic molecular concentration in terms of theoretical limits for the concentration factor and their scaling laws.
We demonstrated how preconcentration and purification efficiencies developed by ICP (Ion Concentration Polarization) were governed by electrochemical reactions using two types of electrode configurations; large exposed electrode area (LEEA) and small exposed electrode area (SEEA).
