A08: High Resolution NMR for Investigating Fluid Behavior on Solid Surfaces
In this project the possibilities of measuring local concentration gradients near a contact line will be explored. Such a capability would greatly enhance understanding between mass transport and wetting. Conventional methods of Nuclear Magnetic Resonance (NMR) will be extended using an in-house 1D micro imaging system with static field gradients and a commercial 3D micro imaging system with pulsed field gradients. A spatial resolution of ~1µm is expected. First investigations will be restricted to quasi-stationary processes. One challenge is to minimize the restrictions in terms of time resolution.
