Surface nanobubbles or Knudsen bubbles?

Vincent S. J. Craig, Physics 4, 70 (2011) – Published September 6, 2011

AFM experiments suggest the long lifetime of surface nanobubbles is due to a balanced influx and outflux of gas molecules.

Fluid Pump without Moving Parts

Phys. Rev. Focus 26, 16 (2010) – Published October 15, 2010

Simulations show that fluid could potentially be pumped in a complete circuit through a nanometer-sized tube if its surface properties are manipulated and it’s heated in the right places.

Synopsis

Small-scale hydraulics

Published October 5, 2009

Rotating electric fields can power the flow of water along a nanochannel.

Cooking up a Smart Nanofluid

Phys. Rev. Focus 23, 9 (2009) – Published March 25, 2009

Water containing specialized nanoparticles can transport heat at two different rates, depending on the initial configuration of the particles. An improved version of this system could help regulate heat flow in devices.
