Superconductivity found in thin films of TiO2

Many of us are familiar with titanium dioxide (TiO2), a whitener commonly used in sunscreens and paints such as the white lines seen on tennis courts. Less well known are other higher titanium oxides--those with a higher number of titanium and oxygen atoms than TiO--that are now the subject of intensifying research due to their potential use in next-generation electronic devices.
