Abstract: Bibliometric techniques (i.e. citation analysis) are used to evaluate the impact and standing of Solid State Communications (SSC) among its competitor journals covering the field of condensed matter. In most cases, the analysis covers all issues dating back to the journal’s inception in 1963. In some cases, however, the analysis only covers articles published after 1973 because of limited access to the previous data under the available search system. A listing of the most cited articles appeared in SSC since its inception is given. Several of them include Nobel laureates among their authors. An analysis of the articles which remained uncited is also presented. Bibliometric data from the Institute for Scientific Information (ISI) such as the Journal Impact Factor (JIF), the Citing Half-Life as well as the Cited Half-Life are compared with those for other journals covering condensed matter and related fields. Furthermore, an analysis of the impact according to the countries of origin of authors is presented. A discussion of the results exhibited in Tables and Figures is given.

Abstract: Proton diffusion in NaHZr(PO₄)₂-5H₂O and Na₂Zr(PO₄)₂-3H₂O phases was examined by studying the kinetics of hydrogen-sodium ion exchange. Three regions characterized by an almost linear dependence of the apparent diffusion coefficients of the hydrogen ion on the pH values were obtained at pH < 7, 7 < pH < 9 and 9 < pH < 11. The phenomenon was explained by different mechanisms of defect formation in the pH ranges investigated. The distribution of the proton defect concentration in the grains was estimated for different pH values, The influence of the anion nature in the contacting solutions on the diffusion coefficients was also discussed. The rate of ion exchange increases in the series: I^- < Br^- < Cl^-, ClO₄^- 3^- 4^2-. (C) 1999 Elsevier Science B.V. All rights reserved.

Abstract: The kinetics and mechanism of diffusion of Zn²⁺, Sr²⁺, Co²⁺ and Eu³⁺ in the H⁺-form of cerium(IV) antimonate (CeSb) have been studied as a function of particle sizes, reaction temperatures and solution concentrations of the exchanging ions. The exchange rate was controlled by particle diffusion mechanism as a limited batch technique. The physical thermodynamic parameters such as, activation energies and entropies of activation have been evaluated. The mobility of these ions inside the particles of the exchanger decrease in the order:

Zn²⁺ > Sr²⁺ > Co²⁺ > Eu³⁺

Abstract: Thermodynamics and kinetics investigation of ion exchange H⁺/M⁺ (M = Li, Na) in tin acid phosphate has been carried out. The equilibrium constants and the cation diffusion coefficients in the exchange products have been determined. It was shown that the diffusion coefficient value in MxH₂ - xSn(PO₄)₂.nH₂O depends strongly on proton concentration in the solution. The cation mobility in tin acid phosphate and its ion exchange products has been investigated by impedance spectroscopy too. It was shown that the ion conductivity of these compounds is determined by the surface contribution and increases with increase in the hydration degree. (C) 2003 Elsevier B.V. All rights reserved.

Abstract: The effect of hydration and benzene adsorption on Na-23 resonance and the quadrupolar interaction in NaY zeolites is studied by triple-quantum MAS Na-23 NMR spectroscopy. In the case of a C6D6/NaY system, the results show that with an increase in benzene loading, there is an up-field trend in isotropic chemical shift (delta(CS)) and a decreasing second order quadrupolar effect (chi(s)) for the site II sodium ions. It was found that adsorbed benzene molecules have a slight effect on the environment of sodium ions on site I. All the sodium sites in NaY are influenced upon hydration. The up-field shift of the sodium delta(CS) reflects the effect of coordination of oxygen atoms on sodium cations due to hydration. The magnitude of chi(s) for hydrated sodium sites increases and then falls off with water loading. The increase in chi(s) is due to the initial hydration among SI-, SI’- and SII-sodium ions, while the decrease is the result of approaching the final stage of saturated hydration.
