Lombardo and Bell (1991) reviewed stochastic models of the description of rate processes on the catalyst surface, such as adsorption, diffusion, desorption, and surface reaction, which make it possible to account for surface structure of crystallites, spatial inhomogeneities, and local fluctuations of concentrations. Comparison of dynamic MC and mean-field (effective) description of the problem of diffusion and reaction in zeolites has been made by Coppens et al. (1999). Gracia and Wolf (2004) present results of recent MC simulations of CO oxidation on Pt-supported catalysts.

The described procedure is the only one that gives a variety of colors which may help the identification of polypeptides separated. It has, however, to be noted that some colors are dependent on the protein concentration. Comparison of the results of different variations of the silver stain method [225,226] and other staining procedures [227,228] proved that the method of Oakley et al. [227] is simple and quickly performed. In the Sammons procedures [224] (see above) the washing steps are rather time consuming but offer superior results. The most complicated procedure is that of Switzer et al. [225]. It must also be noted that the methods of Oakley et al. [227] and Switzer et al. [225] require ammoniacal silver solution which is more difficult to handle than silver nitrate. Also the above described method is the only one that allows more than one gel to be stained at once in the same tray.

Figure 12.15 shows corrosion initiation time as a function of water/cement ratio in the presence of an inhibitor. The simulation was carried out for a 2.54 cm concrete cover and 7.6 kg/m surface chloride concentration. Comparison of Figs. 12.13 and 12.15 shows that rebars better resist chloride attack with an inhibitor for every water/cement ratio. 

Here, Q is the initial solution concentration and Cf is the final solution concentration. Comparison of the k values for the imprinted and control blank gels can show the effect of imprinting on the metal-ion selectivity for a given material. A measure of the increase in selectivity due to molecular imprinting can be defined by the ratio of the selectivity coefficients of the imprinted (MIP) and nonimprinted (NP) materials ... 

Comparison of curves 1 and 4 shows that, with other conditions being equal, the amount of precipitated polymer in the system PaMS+cyclohcxane+octanol exceeds 2.6-fold that one in the. system PaMS- -dioxane- -octanol. Comparison of curves 1 and 2 (Pa.VlS4 dioxanc- -octanol) and curves 4 and. 5 (Pa lS- -cyclohexaiie- -octanol) reveals the effect of a rise in the precipitation degree with polymer concentration. Comparison of curves 3 and 5 provides an example of elimination of the optical distortions by means of shortening the cell length.
