Composite Nanochannels as Nanopumps Driven by Symmetric Temperature Gradients

摘要：

In this work, we propose a composite nanochannel system, where half of the channel is of low surface energy, while the other half has relatively high surface energy. It is shown that fluids in such channels can be continuously driven by a symmetric temperature gradient. In the low surface energy part, the fluid moves from high to low temperature, while the fluid migrates from low to high temperature in the part of high surface energy. The mechanisms that govern the flow are explained.
