Fig. 53. Master plot of transient hole traces in isopropylcarbazole-Lexan film at room temperature in units log i vs log t/t,. The traces were normalized to t,( and shifted along the log i axis for the best superposition [292]...

A subsequent paper also includes results from higher light intensity illumination, conditions under which mass transport can begin to play a role.76) A master plot of the log of the light intensity vs. the log of the reactant concentration...

Figure 27. Master plots of the imaginary parts of the dielectric spectra for 100 mol% (a), 75 mol% (b), and 35 mol% (c) of glycerol measured in the temperature intervals 202-292 K, 197-290 K, and 176-221 K, respectively. The dashed line represents CD law with pCD = 0.58. (Reproduced with permission from Ref. 208. Copyright 2005, American Chemical Society.)...

Moreover, this fitting shows that in the considered temperature-frequency landscape, only the temperature dependence of As = As(T) and r = x(T) is observed, while the other parameters B, (3, A, and q are not temperature-dependent. Thus, the proposed phenomenological model (114) as a modification of the CD function (21) with a conductivity term could be successfully applied for simultaneous fitting of dc-conductivity, the main process, and the EW presented in the master plots (see Fig. 27). 

Since the parameters A and q of the master plot are not dependent on temperature, the ratio x/xo is also independent of temperature that is, the scale To follows the same VFT law as the main relaxation time x (Fig. 37). 

Figure 39 shows the water content dependence of normalized conductivity on the master plots evaluated by using the relation... 

Moreover, the experimental data through dc-conductivity, the main process and the EW could be described by the new phenomenological function (114). If the concentration remains the same, only two variable parameters, As and x, with a set of constants, can describe the whole temperature dependence of spectra. The universality in the master plots of dielectric spectra for glycerol and glycerol-water mixtures has the same origin as elementary molecular processes... 

Figures 6, 7 and 8 are shear modulus and loss factor master plots for HOI as collected by each of the three apparatus. Note that the left ordinate is log G, the right ordinate is loss factor and the abscissa is log frequency. In each case, the plotting reference temperature is 10 C.

E 5 is the root-mean-square field strength at 500 Hz. (From Parthasarathy et al. 1994, with kind permission from Elsevier Science-NL, Sara Burgerhartstraat 25, 1066 KV Amsterdam, The Netherlands.). 

This first requires that one choose a functional form of f(y) so that its integral can be determined for use in eq n. (21). Then a value of Z is guessed and P(y) is calculated for arbitrary values of y and 8. This allows Z to be computed from eq n. (17) and its value is then compared with the one guessed. The procedure is repeated until convergence is obtained. Since these values of P(y) and Z are obtained for arbitrary values of y and 8, a master plot can be constructed and used in a very general fashion. Such...
