Abstract

Lithium ion trafficking: Surprisingly stable and soluble spherical molybdenum oxide based porous nanocontainers/artificial cells (see graphic) interact specifically with their environment, for example, with cations abundant in solution, to incorporate them at well-defined internal cell positions. In the present case, the traffic of Li+ ions between the “outside and inside” is in equilibrium (homeostasis) as measured by NMR spectroscopy. (Li purple, Mo blue, O red)
