چکیده
Robert Schöllhorn* and Wolfgang Schramm Anorganisch-Chemisches Institut der Universität Münster, Gievenbecker Weg 9, D-4400 Münster Z. Naturforsch. 84b, 697-699 (1979); received February 19, 1979 Topotactic Reactions, Intercalation Compounds, Niobium Chalcogenides, Ionic Conductivity, Superconductivity Cathodic reduction of Nb3S4 and Nb3Se4 electrodes in electrolytes containing cations of appropriate size results in the formation of ternary phases A^ [Nb 3 X4p. The cations An+ are taken up into empty channels of the rigid lattice framework and exhibit high ionic mobility at room temperature.

Layered ternary chalcogenides AxMX2 (A = al kali metal, M = transition metal, X = S, Se) of group IV b to VI b elements may be prepared either by reactions a t high temperatures (600-1000 °C) from the elements1 and via alkali halide m elts2 or at low temperatures from the corresponding binary phases MX2 by intercalation of alkali metals from liquid ammonia3. Both series of compounds were found...
متن کاملElectron-Transfer Reactions on Passive Chromium
The kinetics of electron transfer between electrochemically passivated chromium and several outer-sphere redox couples have been investigated as a function of passive-film thickness, d = 5 to 25/~, in 1M H2SO4. The apparent rate of electron transfer decreased exponentially with increasing thickness of the passivating overlayer. Similarly, during potentiostatic film growth, the electron-transfer...

The lining structure of Tunnel Boring Machine (TBM) excavated tunnels is composed of series of precast Reinforced Concrete (RC) pieces which are called segment. At the present paper, a novel method is introduced for seismic retrofitting of segmental tunnels located at active fault zones in rock environment with case study of Amirkabir dam to Tehran water transfer tunnel (Karadj tunnel). The mai...
متن کاملInvestigating ion-surface collisions with a niobium superconducting tunnel junction detector in a time-of-flight mass spectrometer
The performance of an energy sensitive, niobium superconducting tunnel junction (STJ) detector is investigated by measuring the pulse height produced by impacting molecular and atomic ions at different kinetic energies. Ions are produced by laser desorption and matrix-assisted laser desorption in a time-of-flight mass spectrometer. Our results show that the STJ detector pulse height decreases f...

The formation of nano/ultrafine grained ferrite in low carbon steels containing different amounts of niobium was investigated using thermomechanical treatment which consisted of annealing of 85% cold rolled martensite with different parameters. The specimens were characterized by optical and scanning electron microscopy and Vickers hardness test. A lamellar dislocation cell structure was formed...
