by using the recently developed IHSAB model. The optical pumping of a TiO2 and TiO2−xNx decorated interface demonstrates a significant enhancement in the ability to sense NH3 and NO2. Comparisons to traditional metal-oxide sensors are also discussed.

The combination of tailored active interfaces, the ability to confine processes at the nanoscale, and the ability to manipulate nanostructured materials and their interaction at these select interfaces, offers the opportunity to develop
