With increase of Fe content in SrCol-xFexO3-δ from x=0 to x=0.2, the phase composition changed pro- gressively in the order of hexagonal→brownmillerite （main）＋hexagonal→cubic （main）＋ brownmillerite→single cubic phase. Transition between the hexagonal/brownmillerite phase and the cubic phase took place with variation of the operating conditions, and was associated with remarkable changes in the electrical conductivity and oxygen permeation flux.展开更多

The transport of potassium or calcium ion through the liquid membrane, in which the derivatives act as carriers, has been studied. The electron-effect of the substituent on the upper rim of calixarene possesses important effect on the net transport of metal ions. The p- tert-butylcalix[4]arene is the best carrier of calcium ion, compared with p-tert-calix[4]arene（n = 4, 6, 8）. The ptert-butylcalix[4]arene acid is better than p-tert-butylcalix [4]arene. The calixr43crown is the best carrier of calcium ions of all the carriers. The pH gradient between the source and receiving phase, and the concentration of K^＋ , Ca^2＋ ions in the source phase affect mainly transport. After the transport, the pH value of the source phase is found to be decreased, once the calix [n ] arene derivatives act as carrier. But it is not the case for the calix[n] crowns. It might be interpreted as the result of their different mechanisms.展开更多

These are scientifically and technologically important materials with orthorhombic perovskite-like structure and space group Pbnm. Lanthanum ferrite, LaFeO3 is semiconducting and antiferrom agnetically ordered at zero. The thermodynamics of perovskite-type or related materials of potential use in, e.g., solid oxide fuel cells have been studied to a rather limited extent only.展开更多
