We present dissipative particle (DPD) simulations of electrolyte flow in nanochannels for varying salt concentration and surface slip conditions. First, a method is presented by which the slip length δ Β at the channel boundaries can be tuned systematically from negative to infinity by introducing suitable wall-fluid friction forces. Using this method, we study electroosmotic flow (EOF) in nano...

this paper discusses the control of flexible microgrids, consisting of a redox flow batteries (rfb) and a new power conditioning system (pcs) for the rfb. considering the importance of energy storage, this study is essential in power systems that are developed cautiously. rfb is connected to power system by a dc/dc or dc/ac converter to produce a dc voltage. it is very important that this conve...

In this paper, we describe an amperometric-type enzymeless glucose sensing system based on a nanoporous platinum (Pt) electrode embedded in a microfluidic chip. This microchip system is comprised of a microfluidic transport channel network and a miniaturized electrochemical cell for nonenzymatic glucose sensing. Sample and buffer solutions were transferred to the cell by programmed electroosmot...

The ionic current rectification (ICR) is studied theoretically by considering a pH-regulated, conical nanopore. In particular, the effect of electroosmotic flow (EOF), which was often neglected in previous studies, is investigated by solving a set of coupled Poisson, Nernst-Planck, and Navier-Stokes equations. The behaviors of ICR under various conditions are examined by varying solution pH, bu...

Thermal end effects on electroosmotic flow in a capillary are numerically investigated in this paper. The model accounts for the dynamic coupling effects of Joule heating on the temperature field, the electrical double layer field, the applied electric potential field and the flow field in the full capillary from reservoir to reservoir. These fields are strongly coupled via temperature dependen...
