报告摘要:

Generally, asymmetric ion transport phenomena in 1D and 2D nanofluidic systems include the ionic current rectification, and the generation of pressure-driven streaming current and concentration-gradient-driven osmotic current. In the recent years, light-controlled active transport of ionic species in abiotic materials attracts renewed attention. Using the energy of light, a remote, non-invasive, and active control to the membrane transport process can be readily achieved. Specifically, we recently discover an additional asymmetric ion transport phenomenon in 2D layered materials, in which a directional ionic flow can be initiated by a localized visible light illumination on a strip of homogeneous graphene oxide membrane.
