Power Generation by Pressure-Driven Transport of Ions in Nanofluidic Channels

We report on the efficiency of electrical power generation in individual rectangular nanochannels by means of streaming currents, the pressure-driven transport of counterions in the electrical double layer. Our experimental study as a function of channel height and salt concentration reveals that th...
