Controllable fabrication of angstrom-size channels has been long desired to mimic biological ion channels for the fundamental study of ion transport. Here we report a strategy for fabricating angstrom-scale ion channels with one-dimensional (1D) to three-dimensional (3D) pore structures by the ...
A lamellarmembrane assembled by parallel restacking of two-dimensionalnanosheets provides a novel platform for studying the electrostaticmanipulation of ion mobility under angstrom-scale confinement.The membrane nanostructure in aqueous solution is unstable due tointercalation. However, because accurate measuremen...
Ion and water transport at the Angstrom/Nano scale has always been one of the focuses of experimental and theoretical research. In particular, the surface properties of the angstrom channel and the solid-liquid interface interaction will play a decisive role in ion and water transport when the ch...
Ion beam cleaning is a process in which a beam of energetic ions is directed toward a substrate with the intent of removing contaminants. Removal of these contaminants enhances adhesion properties and improves the interface between the film and the substrate. In ion beam etching, the energy of ...
The energy barriers act against ionic movements, which hold the target ion while facilitating the transport of competing ions. The membrane consists of bilayer metal-organic frameworks (MOF-on-MOF), possessing a 6 to 3.4-angstrom passable cavity structure. The ionic current measurements exhibit an ...
A broad-spectrum antibacterial silicate-based angstrom Ag ion-nonoporous material able to kill more than 11 bacteria including ring worm, fungus, candida, blue mold, etc is prepared from the Ag ions and the silicate-base nanoporous material chosen from the molecular sieves of X-ray zeolite, A...
ion transportnanofluidics.Emulating angstrom-scale dynamics of the highly selective biological ion channels is a challenging task. Recent work on angstrom-scale artificial channels has expanded our understanding of ion transport and uptake mechanisms under confinement. However, the role of chemical ...
