Based on such comparisons and taking into account typical uptakes of aromatic solutes (of the order of 0.005 mol/g under most favorable conditions), it is tempting to postulate that the dispersion interactions—which allow a much more effective utilization of the carbon surface—may be the dominant driving force for the adsorption of organic solutes. In particular, aromatic solutes have a natural affinity for the graphene layers on the carbon surface (see Fig. 3) because of the possibility of 7i-7t overlap. Indeed, 7C-7t interactions and 7t-cation complexation are currently very powerful concepts and popular re.search topics [75-77,714,88,715-717,89,90,718,719]. (Thus, for example, the landmark paper by Hunter and Sanders [74] currently has close to 800 citations in the Science Citation Index.)... 

As we remarked in previous works (Cataldo et al. 2010, 2011 Ori and Cataldo 2011) the distance-based index W(N) shows, on D-dimensional structures, a polynomial-like behavior W(N) N (with s = 2 +HD) whose validity has been recently extended to D > 1 fractals (Ori et al. 2011). In case of D = 2 graphenic planes, the Wiener index formula is ... 

In Fig. 3.2 the graphene lattice is represented under an up-down armchair orientation it has N starred nodes and the closed form for its Wiener index is (Cataldo et al. 2011) ... 

Table 1.1 data allow the interpolation of the previously introduced parameters affecting the nature of the bondonic particles of these GNR systems, that after calibration data one gets the 83% correlated Wiener topological index with the working pristine and SW defect graphene s potentials (Putz Ori, 2012)... 

The most common situation is Li intercalation in graphite (Fig. 3a), which proceeds by the so-called staging phenomenon [18]. This staging phenomenon is described by an index, which indicates the number of unoccupied graphene layers between two Li-occupied layers [18, 26]. As already quoted, the maximum intercalation capacity is 372 mAh/g, which corresponds to x = 1 in reaction (6).
