Snapshot of the organization of water molecules and the hydrogen bonds on titanium dioxide.  

The blue-green cloud around the atoms shows the distribution of charge density. Simulations indicate that the hydrogen bond density is higher on the surface of titanium dioxide than on tin dioxide. But, the hydrogen bonds are found to be stronger on tin dioxide than titanium dioxide.
