Versatile reaction-separation model

The versatility of lattice models to describe encounter-controlled reactions in systems of more complicated geometries can be illustrated in two different applications. In this subsection layered diffusion spaces as a model for studying reaction efficiency in clay materials are considered and in the following subsection finite, three-dimensional lattices of different symmetries as a model for processes in zeolites are studied. Now that the separate influences of system size N, dimensionality d (integral and fractal), and valency v have been established, and the relative importance of d = 3 versus surface diffusion (and reduction of dimensionality ) has been quantified, the insights drawn from these studies will be used to unravel effects found in these more structured systems. 

Even a relatively simple bacterial photosynthetic system is very complex and its synthetic imitation is a challenging task. Mimicking of the natural photosynthetic process requires synthetic models of all the crucial components and linking them together into a working molecular assembly. All the elements (antenna, charge separation, and reaction centres) may involve transition metals. Application of metal complexes facilitates mimicking of this complex chemical system due to rich and versatile photochemical processes typical for transition metal complexes (see section 6.4 in Chapter 6) [48].
