Fast-paced and substantial advances in computer and mobile communication technology over the past twenty years meant an equally impressive development of information systems. This is widely experienced through ubiquitous internet access. Already back in the nineties of the last century transport related businesses and institutes saw that potential and consequently spawned a wide range of ICT solutions supporting transport logistics processes as well traffic management. That last-mentioned area of technical solutions is commonly referred to as Intelligent Transport Systems (ITS). 

The McMillan-Mayer theory allows us to develop a fomialism similar to that of a dilute interacting fluid for solute dispersed in the solvent provided that a sensible description of W can be given. At the Ihnit of dilution, when intersolute interactions can be neglected, we know that the chemical potential of a can be written as = W (a s) + IcT In where W(a s) is the potential of mean force for the interaction of a solute... 

Suppose now that we build a series of cells, alike in all respects save that the (very dilute and completely dissociated) solute has a different concentration in each cell. If the cells are alike in all other respects, the unitary terms must be the same in each coll the values of the e.m.f. for the various cells will differ owing to the difference in the communal terms. In very dilute solutions the contribution made to each communal term by the interionic forces will be small, and the dependence of the e.m.f. on the concentration will arise almost entirely from the cratic term which, for each solute species, may be written — kT In y or — IcT In x. Since we are considering a uni-univalent solute, the numerical values of y+ and t/ for the positive and negative ions will both be the same as the mole ratio of the solute. 

The CMC of C14DAO is about 1 x 10 M at 25 C. Below the CMC a typical buffering action is observed (4 x ICT M), above the CMC the titration curves are slanted toward lower pH s with increasing HCl concentration 0.2 M having a steeper slope than 8 X 10 M. Addition of SDS to a solution of C DAO affects the HCl titration curve markedly and will be discussed later. 

Whereas 2,2-diphenylhexamethyltrisilane (8) is a well-known photochemical precursor of diphenyl si ly Icnc72,155 156, a 1,3-silyl migration is usually a major side reaction in solution at room temperature. In the presence of excess ethanol, the irradiation of 8 in hexane gives 9 via diphenylsilylene extrusion and 10 (an isomeric mixture) via 1,3-silyl migration in 50 and 37%, respectively (Scheme 3)157. Since the product ratio does not depend on the solvent polarity, both reactions, silylene extrusion and 1,3-silyl migration, do not occur via the ICT state but via the nonpolar excited state158. However, the excited... 

Fischer, T. S. et al., Int. Annu. Conf. ICT, 1996, 27th(Energetic Materials), 107 Used industrially as a powerful reducant, it is supplied as a solution in hydrocarbon solvents. The undiluted material is of relatively low thermal stability (decomposing above 50°C) and ignites in air unless diluted to below 25% concentration [1]. A thermal explosion of the compound has been studied from a theoretical standpoint [2]. See other TRIALKYLALUMINIUMS... 

The confinement of a relatively large number of dye molecules in the small volume of a nanoparticle may trigger collective phenomena otherwise not observable in bulk solution. This has been demonstrated by Prasad and coworkers in the case of an ORMOSIL pH sensor.69 The PEBBLEs contain a naphthalenylvinylpyridine derivative (NVP) as pH-sensitive fluorescent dye which has been functionalized with a triethoxysilane anchor by reaction with an excess of (3-isocyanatopropyl)triethoxysi-lane (ICTES). The sol-gel polymerization in aqueous micellar solution of the NVP-ICTES derivative with VTES gives spherically shaped 33 nm silica nanoparticles in which the dye is covalently linked to the silica matrix and uniformly distributed in the nanoparticle volume. The NVP dye responds ratiometrically to protons, with a...

As we have noted the data reported in Table 7-3 refer to Franck-Condon ICT states it thus becomes interesting to analyze the effects of both the solute and the solvent relaxation. For the apolar cyclohexane, solvent relaxation effects are null whereas they are large for the polar acetonitrile, as shown in Table 7-4 in which we report the evolution of the dipole moment and of the NBO charges of the ICT state of PNA in acetonitrile when we allow both solvent relaxation and solute geometry relaxation.
