chemical compositionreaction abilityXPSUPSThe photoelectron spectroscopy technique has been used to study the oxygen species on the surface of powdered ZnO which are reactive with CO. The experiments were performed over the 30-160 eV range of photon energies using Mg X-rays. It was found that ...
studied the critical behaviour of La0.6Ca0.2Sr0.1MnO3 samples synthe- sised by sol–gel and solid-state reaction, and the particle variation has been identified as the leading cause of the property changes [31]. Reduction in the particle size was also discov- ered by Arun et al. when ...
2. Materials and Methods Polycrystalline samples were prepared by conventional solid-state reaction. High purity oxides of principal elements Pr6O11, SrO, MnO2, and carbonate CaCO3 were pur- chased from Alfa Aesar (Heysham, UK). After being mixed by hand in a mortar for 3 h, the powders ...
, Co(NO3)2∙6H2O, Ni(NO3)2∙6H2O (AR, 98%, Tianjin Kemi Ou Chemical Reagent Co., LTD.) were dissolved in deionized water to create a metal salt solution. In parallel, an excess of NaOH (AR, 96%, Tianjin Huadong Reagent Factory) and anhydrous Na2CO3 (AR, 99.8%, Tianjin ...

The reaction of methane with oxygen from La0.8Sr0.2FeO3-未 (LSF) and several LSF-Fe2O3 configurations was studied in chemical looping mode. Shell (LSF) and core (Fe2O3) (four catalysts called CS-3, CS-4, CS-5 and CS-6, over a range of coverage), LSF mixed uniformly with Fe2...
Surface reaction mechanisms in the chemical vapor deposition of (Ba, Sr)TiO_3 [BST] films were studied by investigating the effects of O_2 gas and source supply ratios on the characteristics of atomic incorporation rates. The atomic incorporation rates of Ba, Sr and Ti increased with ...
The reaction cross sections decrease with the increasing collision energy when the collision energy changes from 0.1 to 1.0 eV.Wen Wen Xia and Li Yao and Baojiu ChenJournal of Molecular Structure: THEOCHEM
The vibrational distribution, rotational distribution, reaction cross section, and rotational alignment of the product SrI were calculated, and the mechanism of the title reaction has also been discussed. The calculated vibrational and rotational distributions show that their peak values are located atv=...
The vibrational distribution, reaction cross section and product rotational alignment of the reaction Ba m-C6H4ClCH3 have been calculated, and the reaction mechanism has also been discussed. When the collision energy equals 1.08 eV, the peak value of the vibrational distribution is located at v =...
