"switching off electrically driven ion flow in 1 direction through nanopore poret... if pore surface negatively charged, negative ions interact with it rather than pass through, and only positive ions flow, taking energy with them... high (low) ion concentrations from increased (decreased) electricity = increased (decreased) temperature... scalable... generate electric potential using temperature gradient... temperature sensing, blue energy harvesting, microelectronics, nanomedicine"
