“…Their analyses in different temperature regimes allowed them to extract a migration barrier for the current-carrying defect, with a value E m =0.53 eV [8] or 0.54±0.02 eV [9]. This is in very good agreement with our calculated migration barrier of 0.51 eV for the V − Li and V + H defects (see Table I).…”

“…Experimental values for the ionic conductivity were reported by Varotsos and Mourikis [8] and Ikeya [9]. Their analyses in different temperature regimes allowed them to extract a migration barrier for the current-carrying defect, with a value E m =0.53 eV [8] or 0.54±0.02 eV [9].…”

“…Other experimental observations include the production of H − ions by heating LiH in vacuum [6], and loss of hydrogen from LiH surfaces at room temperature, causing the formation of a lithium metal phase [7]. Regarding the ionic conductivity, LiH was reported to have an activation energy of 1.70±0.10 eV and a cation vacancy migration barrier of 0.54±0.02 eV [8,9]. A detailed understanding of these reactions and phenomena is still lacking, largely due to the absence of information about the formation and migration of native point defects in LiH.…”

“…Before an earthquake, the pressure increases in the future focal area and produces changes in various physical properties like porosity, conductivity , dielectric constant (Varotsos, 1978(Varotsos, , 1980, etc. In addition, it affects the relaxation time of electric dipoles which are formed in an ionic solid between introduced aliovalent impurities (Varotsos and Miliotis, 1974) and vacancies created for charge compensation (Varotsos and Mourikis, 1974;Kostopoulos et al, 1975). This relaxation time, τ , is given by the equation…”

Abstract. The power law relation between the stress drop of "non thrust" earthquakes and the lead time of precursory Seismic Electric Signals (SES), obtained by Dologlou (2008a), has been tested by using additional data from the most recent earthquake that occurred on 8 June 2008, in Andravida, NW. Peloponnesus, Greece and from two other destructive earthquakes that occurred in the past in Ionian sea. A critical exponent α=0.33 is derived which is close to the one (e.g. 0.29) reported by Dologlou (2008a). The above preliminary result strengthens the hypothesis that probably signatures of criticality are present in the earthquake preparation and precursory SES processes and that both phenomena are governed by same physics.

A simple model for calculating the compressibility of the transition-metal carbides and nitrides alloys ZrxNb1−xC and ZrxNb1−xN

The 4d-transition-metals carbides (ZrC, NbC) and nitrides (ZrN, NbN) in the rocksalt structure, as well as their ternary alloys, have been recently studied by means of a first-principles full potential linearized augmented plane waves method within the local density approximation. These materials are important because of their interesting mechanical and physical properties, which make them suitable for many technological applications. Here, by using a simple theoretical model, we estimate the bulk moduli of their ternary alloys ZrxNb1−xC and ZrxNb1−xN in terms of the bulk moduli of the end members alone. The results are comparable to those deduced from the first-principles calculations.
