Thin Water Acts Like a Solid 138
Roland Piquepaille writes "What happens when you compress water in a nano-sized space? According to Georgia Tech physicists, water starts to behave like a solid. "The confined water film behaves like a solid in the vertical direction by forming layers parallel to the confining surface, while maintaining it's liquidity in the horizontal direction where it can flow out," said one of the researchers. "Water is a wonderful lubricant, but it flows too easily for many applications. At the one nanometer scale, water is a viscous fluid and could be a much better lubricant," added another one."

Alright, you know, if you had asked me this question, way back when, I would have said it acts like a solid. Why is this news, am I missing something?

OK, I read the paper, DOI: 10.1103/PhysRevB.75.115415.
They did experiment with a Molecular Iamge PicoPlus AFM with the funny sound proof box and rubber bands, if you saw such a system you will know what I mean. The tip they used had a stiff cantilever and was "likely to be oxidized". They carefully controlled the sample surface and make it perpendicular to the tip. And they did the experiment on three surface, mica, soda lime untreated glass and highly oriented hydrophobic graphite.
And the result is hydrophilic surfaces showed increased viscosity and the hydrophobic surface showed no change.

If I'm not mistake, solid water isn't actually slipper in and of itself.. its the thin layer of liquid water we create whenever touching it and applying pressure. Look up curling [wikipedia.org].
Of course I'm open to enlightenment if I've got something wrong.
