(Figure Presented) Does water suffer from claustrophobia? The local structural and dynamic properties of water in confined (300-4000 nm) spaces were characterized by an NMR study of the size-dependent relaxation phenomena, which in turn reflect changes in water mobility and proton transfer. The results are important for understanding fluidics in extended nanospaces and in implementing micro-/nanofluidic devices. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
