Atomic layer deposition method was used to grow thin films consisting of ZrO2 and MnOx layers. All depositions were carried out at 300 oC. Some characteristics the manganese(III)acetylacetonate ozone process investigated, such as crystallinity dependence growth rate on temperature. partly crystalline in their as-deposited state. Zirconium oxide contained cubic tetragonal phases ZrO2, while mang...

Using a combination of high-angle annular dark-field scanning transmission electron microscopy and atomically resolved electron energy-loss spectroscopy in an aberration-corrected transmission electron microscope we demonstrate the possibility of 2D atom by atom valence mapping in the mixed valence compound Mn3O4. The Mn L(2,3) energy-loss near-edge structures from Mn2+ and Mn3+ cation sites ar...

SrMnO3 is a potential solid oxide fuel cell (SOFC) cathode material. However, the formation of different crystalline phases and poor sinterability restrict its application as in SOFC. Thus, present study focused on synthesis monophasic using sintering temperatures with variable durations. The X-ray diffraction confirms gradual transformation hexagonal to orthorhombic SrMnO3. Minor amounts Hausm...

Hollow structuring has been identified as an effective strategy to enhance the cycling stability of electrodes for rechargeable batteries due outstanding volume expansion buffering efficiency, which motivates ardent pursuing on synthetic approaches hollow materials. Herein, intriguing route, combining solid precursor transition and Ostwald ripening (SPTOR), is developed craft nano single-crysta...

A solid state synthesis of calcium manganite (CaMnO3) is described where equimolecular mixtures CaCO3:MnCO3 have been subjected to mechanical stress (high energy milling) so yielding CaCO3-MnCO3 solid solutions of nanometric particle size. TG measurements have shown that a link exists between milling time, the extent of non-stoichiometry and the milling-induced decomposition of MnCO3 to Mn3O4. ...
