Nonscalable size regime

Analogous effects have also been discussed for the reactivity of different bulk metal surfaces, where the center of gravity of the d-band determines the bonding [350]. In this case, the effects on the reactivity are considerably smaller than in the case of clusters in the nonscalable size regime and are size independent. Additional factors that change the d-band structure for a particular element are strain effects and the crystallographic orientation of the respective surface plane (see Chap. 3). 

In this chapter, we focus on recent experimental and theoretical studies of chemical and catalytic properties of gas-phase metal clusters and metal clusters deposited onto support materials with sizes in the nonscalable regime.
