Journals Russian, distribution

The report gives eonsideration to the eontribution of the seientists from Russia to the development of XRF analysis in the period from 1999 to nowadays. The state of XRF in the earlier period was diseussed in the reviews. Presented in detail are only the most important advanees eonneeted to the speeial features of XRF method. The reviews and the monographs, published in this period, the Conferenees on XRF problems, held in Russia, the defended dissertations are separately diseussed (-380 papers, 5 monographs and 17 dissertations). The statistieal analysis of the publieations on XRF is presented (the distribution in the Russian and foreign journals and in the towns Moseow, Irkutsk, Novosibirsk, St. Petersburg and others). 

The explicit mathematical treatment for such stationary-state situations at certain ion-selective membranes was performed by Iljuschenko and Mirkin 106). As the publication is in Russian and in a not widely distributed journal, their work will be cited in the appendix. The authors obtain an equation (s. (34) on page 28) similar to the one developed by Eisenman et al. 6) for glass membranes using the three-segment potential approach. However, the mobilities used in the stationary-state treatment are those which describe the ion migration in an electric field through a diffusion layer at the phase boundary. A diffusion process through the entire membrane with constant ion mobilities does not have to be assumed. The non-Nernstian behavior of extremely thin layers (i.e., ISFET) can therefore also be described, as well as the role of an electron transfer at solid-state membranes.
