Nanofluidic reverse electrodialysis platform using controlled assembly of nanoparticles for high power energy generation

This paper presents a novel microplatform for high power energy generation based on reverse electrodialysis. The effective cation-selective membrane for power generations is realized between two microfluidic channels using geometrically controlled in situ self-assembled nanoparticles with cost-effective and simple way. Nano-interstices between the assembled nanoparticles have a role as the collective three-dimensional nanochannel networks and they can increase the generated power, significantly. The proposed system can contributes to supply power sources to miniaturized devices and be also used to studies and investigate nanoscale electrokinetics by changing sizes, materials, and shape of the assembled nanoparticles, or geometry control of microchannel.
