water properties article summary

This article is about how scientist have been studying properties of water by using  sheets of carbon and using tunneling microscopes to see how water coats the surface at room temp. They have discovered that water molecules are hard to study cause they do not sit still for very long "in constant Flux." To make the molecules stay still they accidentally they came across a technique to hold them still at room temp. using a thin layer of carbon mesh "Graphene" only one atom thick water molecules are held still under the mesh. the structures under this became more notice able in higher humidities. They had discovered that on mica the molecules were actually two molecules thick. they look like little islands. They are trying to use what the have discovered to study all surfaces like adhesion and lubricants. this study was provide by the u.s department of energies offices of basic energy science.
