Nanoscale Fluid Transport: Size and Rate Effects

Nanoscale fluid transport: size and rate effects.

The transport behavior of water molecules inside a model carbon nanotube is investigated by using nonequilibrium molecular dynamcis (NMED) simulations. The shearing stress between the nanotube wall and the water molecules is identified as a key factor in determining the nanofluidic properties. Due to the effect of nanoscale confinement, the effective shearing stress is not only size sensitive b...

Nanoscale Fluid Mechanics: Transport in Microfluidic Devices

Microand nanofabricated devices have led to revolutionary changes in our ability to manipulate tiny volumes of fluid or microand nanoparticles contained therein. This has led to countless applications for chemical and particulate separation and analysis, biological characterization, sensors, cell capture and counting, micropumps and actuators, high-throughput design and parallelization, and sys...

Size effects and strength fluctuation in nanoscale plasticity

Stochastic, discontinuous flow is ubiquitous in the plastic deformation of small-volume metallic materials. We have identified a sizestrengthening effect on the stress to initiate the jerky plastic yielding in nanoscale volumes of copper single crystals, subjected to nanoindentation in different orientations. Such a nanoscale size effect arises due to the stochastic nature of dislocation source...
