Pressure-driven water flow through a carbon nanotube controlled by a lateral electric field

Abstract

Tuning the water flow through nanochannels provides a key to many physicochemical phenomena, such as energy harvesting, desalination, biosensors and so on. Electric field has been proven to be an...

Fabrication and study of a high output power flexible fabric hydrovoltaic generator

“…18 Su's team found that the lateral electric field strongly affects the dynamics of single-file aqueous chains, which has important implications for the design of novel gated nanofluidic devices. 20 Liu et al experimentally found that MXene membranes with a large number of negatively charged two-dimensional nanocapillaries in a 5 kPa aqueous solution of 0.01 M NaCl produced a flow current density as high as 1.3 mA m and an output of 0.29 μW m −2 power density. 21 Although nanohydroelectric technology offers attractive advantages and many scholars have proposed to increase the duration of power generation; for example, Yao et al prepared an ultrathin nanoscale protein film that can maintain a sustainable power generation output of 0.55 V and 250 nA for 2 months.…”
