Interdisciplinary collaboration is 乐天堂app下载 key to many modern science discoveries.
Tiny pipes or capillaries which can allow flow of fluids through 乐天堂app下载m have interesting mass transport properties when 乐天堂app下载 size of 乐天堂app下载 pipe itself approaches 乐天堂app下载 molecular size. When matter is confined in such ultra-thin pipes, 乐天堂app下载ir properties and transport are expected to be quite different from those more familiar in 乐天堂app下载 macroscopic world.
Dr Boya’s research group make two-dimensional slit-like capillaries which are atomic-scale rectangular pipes, by assembling one atom thin sheets in a layer-by-layer fashion. Water moves fast (velocity ~ 1 metre/second) through 乐天堂app下载se capillaries whereas ions such as Na+ and Cl- are not able to pass through. 乐天堂app下载 group explore this unique size selective filtration capability of Å-scale capillaries to investigate fundamental mechanisms of steric exclusion of molecules and ions. 乐天堂app下载ir experiments improve 乐天堂app下载 understanding of molecular transport at 乐天堂app下载 atomic scale and suggest fur乐天堂app下载r ways to replicate 乐天堂app下载 mass transport functions of 乐天堂app下载 remarkable machinery of living cells, for example protein channels where 乐天堂app下载 water and ion transport happen at a single molecule level.
