Water Transport through Carbon Nanotubes with the Radial Breathing Mode Qi-Lin Zhang ,2, Wei-Zhou Jiang*,Jian Liu, Ren-De Miao, Nan Sheng Department of Physics, Southeast University, Nanjing 211189, China 2 Department of Mathematics and Physics, Anhui Polytechnic University, Anhui 241000, China 3 Shanghai Institute of Applied Physics, Chinese Academy of Sciences, Shanghai 201800, China Institute of Science, PLA University of Science and Technology, Nanjing 211101, China Molecular dynamics simulations are performed to investigate the water permeation across the single-walled carbon nanotube (SWCNT) with the radial breathing mode(RBM) vibration. It is found that the RBM can play a significant role in breaking hydrogen bonds of the water chain accordingly increasing the net flux drama+, and wedmninm dwnetinnllw +h mher ef water molecules inside the tube with 70 from this frequency region the trans RBM.
