纳米水通道内水的流动特性研究

The behavior of water transportation across nanometer size channels

  • 摘要: 由于纳米水通道在水处理方面的潜在应用以及它与生物水通道的相似性,人们对纳米水通道的研究受到广泛重视.文章重点介绍了近10年来在纳米水通道方面的研究进展,特别是在外力或外电场扰动下,纳米碳管内水的流动特性.主要包括:热噪音环境下受控水通道内水流的开关特性;外电场驱动下纳米管道内水流的行为;受生物水通道的复杂结构启发的纳米水泵设计.

     

    Abstract: The transportation of water across nanochannels has received extensive attention due to potential applications in water treatment and because of its similarities with biological water channels such as aquaporins. This article reviews some recent progress in the understanding of water transportation across nanochannels. We will focus on the on-off gating behavior in response to external mechanical and electrical signals and noise, enhancement by structure outside the channel, and uni-directional transportation driven by charges close to a channel or electric field.
