• . The presence of Pd NPs on ZnO NRs strongly affects gas adsorption and reactivity and, hence, the gas sensing as discussed in the following section. Gas-sensing performance Figure 4A shows the time responses of the electrical resistance of chemiresistors based on pristine and Pd-modified ZnO NRs to

• affects the ZnO morphology and crystallinity, the distribution of Au dopants on the ZnO nanostructures, and the chemical composition at the interface between the two systems; therefore, it should strongly influence the ZnO properties concerning the gas adsorption and reactivity, as discussed in the next

• reasonable steps would be (a) to attempt to achieve a hexagonal cluster distribution on the w'-TiOx phase by varying the metal deposition rate and/or the substrate temperature as was the case for metal clusters on Al2O3/Ni3Al(111), and (b) the investigation of the electronic as well as the adsorption and

• reactivity properties of the Pd clusters. In this regard, the influence of the two different titania films on these properties of clusters of the same metal is of particular interest [21].

• transport across the kink lines. We finally consider pseudo-ribbon-based heterostructures and propose that such structures present a novel approach for band gap engineering in nanostructured graphene.
