In this work, solid solutions of La 0.7 Sr 0.3 Mn 0.9 5Fe 0.05 O 3-δ with different oxygen content were obtained by the solid-phase reactions technique. Based on investigation dynamics changes in index (3 – δ) during heating samples, formation a stressed state their grains as result annealing was established. This results decrease mobility vacancies reduction cations according to 4+ + e → 3+ sc...
The maximum conductivity achievable in Al-doped ZnO thin films prepared by atomic layer deposition (ALD) is limited by the low doping efficiency of Al. To better understand the limiting factors for the doping efficiency, the three-dimensional distribution of Al atoms in the ZnO host material matrix has been examined on the atomic scale using a combination of high-resolution transmission electro...
We present experimental photoemission and inverse photoemission spectra of SrTiO3−δ representing electron doped d 0 systems. Photoemission spectra in presence of electron doping exhibit prominent features arising from electron correlation effects, while the inverse photoemssion spectra are dominated by spectral features explainable within single-particle approaches. We show that such a spectral...
Development of a novel CO<sub>2</sub> splitting fixed-bed reactor based on copper-doped cerium oxide
Abstract Global warming has received widespread attention in recent years due to the accumulation of carbon dioxide. Looking at current energy landscape, new technologies must be developed reduce CO 2 emissions. The present work is aimed develop and test a prototype an innovative reactor for conversion into CO, operating according two-phase thermochemical cycle. main aspect this study was use c...
