Is anyone familiar with a recent report where liquid water has been condensed inside a carbon nanotube and then imaged with an electron microscope at very low pressure (10^-5 torr)? Supposedly the water does not evaporate at this low a pressure. Is this truly possible and why? Does anyone have the reference for this experiment?

This is possible. When liquids are constrained inside solid devices, its behavior can suffer dramatic changes. In the case of water, confinement produces marked loss of structural order and modifications in its microscopic dynamics.
