Rb + distribution

It was shown by Roux (1974) that the two ideal sites model applies perfectly to partitioning of Rb distribution between nepheline and hydrothermal solutions. Based on the experimental work of Roux (1974), deviation from ideality in the normalized Rb/Na distribution between nepheline (X.) and hydrothermal solution (Xaq) is detectable for X, values higher than 10 (figure 10.3A) Distribution constant Xin the Nemst s law range is Kq = 0.82 (Roux, 1974), and the modification of K with increasing X, is well described by equation 10.20, within experimental approximation (figure 10.3B). 

SEI electrode is extremely complex and must be represented by a very large number of series and parallel distributions of parallel RC elements (Fig. 13b). Since the exact composition, size, and distribution of these particles are generally unknown, we prefer to make the following approximations [5, 6] the contributions RB of all particles (in the same sublayer) are com... 

Since the majority of the elements in surface dust arise from deposited aerosol and added soil it is not surprising to find strong linear relationships between the concentrations of the elements in an atmospheric dust and street or house dust. This is illustrated by the two examples given in Fig. 8 for remote house dust vs urban atmospheric dust and street dust vs rural atmospheric dust. As discussed above crustal/soil material is a major component of atmospheric dust and the soil based elements in the atmospheric dust are Al, Ca, Fe, Mg, Mn, Ni, K, Si and Ti. The elements As, Br, Cd, Cl, Co, Cu, Pb, Rb, Se, V, and Zn are, on the other hand, enriched in atmospheric dust. The same elemental distribution applies to surface dust, but in this case their concentrations (compared on a mass basis) are reduced presumably due to dilution with soil. However, the elements enriched in the atmosphere remain enriched in the surface dusts.

The integrated mass distribution of the metallic film components is shown in Figure 4.32, and a concentration of 0.20 0.03 at% is extracted. For higher concentrations of dopant the precision is much better. Figure 4.33 depicts the results of the dopant analysis by Bohne et al. (2000), compared with the nominal concentration of Cr dopant added during film growth. Standard RBS and heavy-ion...

The anion distribution in anodic oxides is usually determined by ion bombardment or chemical sectioning of alumina samples with subsequent analysis by AES or XPS methods, or by the use of the depth-resolving techniques, such as RBS.150 Different types of concentration profiles are shown in Fig. 27. 

Recent data provided by Cocke et a/.174,175 in an RBS study of the distribution of heavy anions (tungstates, molybdates, manganates) yield unusual oscillatory anion profiles. 

Considering this chain of electrical resistors, we should take into account the influence of the binder (dielectric) effecting on all the above contact resistances in the circuit and increasing their value (Rb). Evidently, the main influence on the ESR of electrode is this circuit because of a big number of contact resistances distributed in the bulk of the electrode. 

Figure 2. Relative amounts of various iron species deduced from 57Fe Mossbauer spectra of the Fe-exchanged samples shown in relation to the progress of the hydrothermal crystallization process at 80°C (A), 57Fe Mossbauer spectra of the Fe-exchanged samples after 0 (a), 120 (b), 180 (c) and 240 min (d) of the hydrothermal crystallization process at 80°C (B) and RBS spectra collected on five different particles of the sample crystallized for 240 min (C). The position of surface Fe in Fig. 2C is marked by the vertical arrow. Depth scale (depth into each particle) is increasing toward left (marked with the horizontal arrow). Fit to experimental data with assumed homogeneous depth distribution of Fe is marked with the continuous line.
