Semiconducting behavior over all studied ranges of frequency and temperature was observed. This behavior is attributed to the cation-anion-cation interaction, which is most predominant at B-sites in these samples. Variation of the universal exponents with temperature indicates the prese...
Since certain metallic elements produce cations with varying positive charges, the names of ionic compounds derived from these elements must describe the cation charge.Answer and Explanation: The cation of an ionic compound is called first, followed by the anion. The cation and its element have th...
ionization laser power,among other variables.[21,22]The most stable clusters observed under conditions of excess oxygen are of the form FemOm and FemOm+1,2.Wang et al.measured the infrared spectra of mass-selected0oxygen-rich cation complexes in the gas phase and studied the geometric and el...
The investigation in this thesis focuses on the synthesis of cation-ordered perovskite phases by introducing anion vacancies into the structure. Complex ca... Luo,Kun - University of Oxford 被引量: 0发表: 2013年 Phase Change of NaFeO2 during Electrochemical Na Intercalation and Deintercalation: An...
A structurally based viscosity model for fully liquid silicate slags has been proposed and applied to the Al 2 O 3 -CaO-'FeO'- SiO 2 system at metallic iron saturation. The model links the slag viscosity to the internal structure of melts through the concentrations of various anion/cation ...
Cation ordered and anion-vacancy ordered perovskite materials The polar structure of Ba2YFeO5.5 is confirmed by the observation of second-harmonic generation activity and pyroelectric behaviour. Ba2YFeO5.5 also ... Luo,Kun - University of Oxford 被引量: 0发表: 2013年 Multiferroic and magnetoelectr...
What is the name and formula of the compound formed between the cation Ca2+ and the anion O2-?What is the empirical formula of a compound composed of 22.9 g potassium (K) and 4.69 g oxygen (O)?What is the empirical formula of a compound comp...
(Bi,Na)-site and Ti-site, respectively, were exhibited the strong ferromagnetism at room temperature where the magnetization were found to great enhancement than that of single transition metal dopants which were possible resulted from co-modification at A-site via alkaline- earth and Fe cation ...
One Na atom, located on a twofold axis at = 0 and tetrahedrally coordinated by four sulfate O atoms of two [FeO(SO)(HO)]units, plays a key role in generating the noncentrosymmetric structure. Three of the seven different cation sites are on twofold axes (one Nasite and two Cs...
The general formula of spinel ferrites is AB2O4 where A and B are metal cation located at distinct crystallographic positions when A represent (Ni2+) at octahedral sites and B represent (Fe3+) at tetrahedral sites [24,25]. However, the nature of the selected metal cation and their arrange...
