Discovery will allow more sophisticated work at nanoscale: New method of fluid gating has implications for drug delivery, power generation and other uses

The movement of fluids through small capillaries and channels is crucial for processes ranging from blood flow through the brain to power generation and electronic cooling systems, but that movement often stops when the channel is smaller than 10 nanometers. Researchers have reported a new way to stimulate the fluid flow by using a small increase in temperature or voltage.
