The microscopic structure of of water [and ice] in carbon nanohorns by neutron diffraction on GEM has shown that water has a density that is ~20% lower than the normal liquid with enhanced local hydrogen-bond correlations. It therefore appears that the hydrophobicnature of the carbon interface effectively isolates the water from surrounding substrate. A previous DINS experiment on this system showed unexpected difficulties in the gas adsorption procedure. Data recorded at room temperature however revealed interesting differences from previously measured water in hydrophilic silica xerogels and MCM-41. We propose a continuation experiment with stabilized and controlled water loading to measure in the supercooled phase at 250 K , as stated in the original proposal, and a stable-hydration reference measurement at 293 K.
