Mixed valencies system Sr 1Àx La x PbO 3Àd (0 6 x 6 0.15) has been prepared by solid state reaction at 900 °C. All solutions crystallize in a distorted perovskite structure and were carefully examined by chemical analysis and X-ray diffraction. The La 3+ -substitution was checked via the linear depe

In the framework of a series of studies carried out by our research team, the excess molar enthalpies H E m and excess molar volumes V E m for 21 binary mixtures composed of one of three butyl esters (ethanoate, propanoate, and butanoate) and one of seven odd n-alkanes (pentane to heptadecane) were
## Sm x Sr 1 -x CoO 3 -ı (SSCx) materials are promising cathodes for IT-SOFCs. The influence of Sm content in SSCx (0.2 ≤ x ≤ 0.8) oxides on their oxygen nonstoichiometry, oxygen desorption, thermal expansion behavior, electrical conductivity and electrochemical activity for oxygen reduction is sy
Excess molar enthalpies H E m and excess molar volumes V E m were determined at the temperature 298.15 K for 21 binary mixtures of three propyl esters (ethanoate, propanoate, and butanoate) and seven odd n-alkanes (pentane to heptadecane). All the mixtures exhibited endothermic enthalpies which decr
