Recently, Prof. Chen Yunfei from the School of Mechanical Engineering of Southeast University published a paper titled “Drastically Reduced Ion Mobility in a Nanopore Due to Enhanced Pairing and Collisions between Dehydrated Ions” in the Journal of the American Chemical Society (JACS), which was founded in 1879 by the American Chemical Society, more than 130 years ago. It is one of the most influential international journals in the field of material and chemistry.

Based on the findings of Prof. Chen Yunfei's team about ion transport in the nanopore, the ion mobility in the nanopore under high concentration has been greatly reduced due to pairing and collision enhancement among some partial dehydrated ions; thus the transport rule of ions in a confined space has become the ideal research object of nanofluid dynamics. The discovery and understanding of any new phenomenon will deepen people’s understanding of classical fluid mechanics. This research relied on Jiangsu Key Laboratory of Micro-Nano Biomedical Device Design and Manufacturing, expecting its achievements to be widely applied in DNA sequencing, seawater desalination, salt energy generation and supercapacitors, etc..

It is reported that Professor Chen Yunfei's team has also made breakthroughs in the research of nanopore confinement. The backbone members and young teacher Si Wei and Prof. Sha Jingjie published papers in high-level journals such as Small, Nanoscale and Analytical Chemistry respectively. Among others, Small, published by Wiley-VCH Group, is ranked among the top multidisciplinary journals (TOPjournalof Chinese Academy of Sciences) with research articles about nano and micro scale covering material science, chemistry, physics, engineering, medicine and biology, etc..
