Genie in a Channel — •Stefan Reutter — TU Darmstadt

When high-energy heavy ions are shot at a thin sample (< 100 µm), they leave a large number of parallel ion tracks. These can be etched to obtain mesoscopic cylinders with a narrow diameter distribution whose mean can be varied between 30 nm and 1 µm.

These channels can then be filled with a liquid to investigate properties such as diffusion and phase behaviour when trapped in a volume small enough that confinement effects become significant, but at the same time large enough that surface effects do not have a dominating influence on liquid dynamics.

I will present the results of diffusometry measurements on simple liquids and binary liquid systems in ion track channels obtained by Static Field Gradient Echo NMR experiments.
