Types of single particle symmetry breaking in transition metal oxides due to electron correlationVery accurate wave functions are calculated for small transition metal oxide\nmolecules. These wave functions are decomposed using reduced density matrices\nto study the underlying correlation of electrons. The...
The N-type NGO comprises either pure or doped materials of any one of TiO2, SnO2, ZnO, NiO, MnO, CoO, FeO, Fe2O3, V203, Mn203 and Ti203. The PV cell employs environmentally friendly metal oxides derived from sustainable natural resources. 展开 ...
Usually they are metal oxides (that is, compounds of metallic elements and oxygen), but many ceramics (especially advanced ceramics) are compounds of metallic elements and carbon, nitrogen, or sulfur. In atomic structure they are most often crystalline, although they also may contain a combination...
Metal-based bis- catecholate- and tris-catecholate-coordination complexes were constructed based on the atomic structures of catechols and typical coordination complexes in metal oxides (planar square for the bis-complex and octahedron for the tris-complex). Metal- catecholate complexes were chosen ...
oxidescontain O2−ions or oxygen atoms,hydridescontain H−ions or hydrogen atoms,sulfidescontainS2−ions, and so forth. Subclasses of organic compounds includealcohols(which contain the ―OH group),carboxylic acids(characterized by the ―COOH group),amines(which have an ―NH2group), and so ...
Trace element composition of iron oxides from IOCG and IOA deposits:relationship to hydrothermal alteration and deposit subtypes. Mineralium Deposita 54, 525-552, https://doi.org/10.1007/s00126-018-0825-1. [34] Huang, X.W., Sappin, A.A., Boutroy, E., Beaudoin, G., Makvandi, S.,...
Thermistors are typically ceramic semiconductors. In most cases they are composed of metal oxides, which are dried and sintered to obtain the desired form factor. The types of oxides and additives determine their characteristic behavior. For NTC thermistors, common materials include cobalt, nickel, ir...
Dissolved oxygen in water column (A) and sediment (B) of each treatment 在实验结束时测量植物根际的沉积物溶解氧浓度, 穗花狐尾藻组、黑藻组和空白对照组沉积物溶解氧浓度随深度发生极小的变化, 两种冠层型植物组沉积物溶解氧浓度甚至在2 cm以上深度还略低于对照组(图3B)。刺苦草组沉积物中溶解氧浓度在6 ...
Fossil fuel combustion has a number of negative environmental consequences. Fossil-fueled power plants emit air pollutants such as sulfur dioxide, particulate matter, nitrogen oxides, and toxic chemicals (heavy metals: mercury, chromium, and arsenic), and mobile sources, such as fossil-fueled ...
Ferritesare oxides of iron with the formulaMFe2O4, whereMis a divalent ion such as nickel, zinc, cadmium, manganese, or magnesium. The ferric iron ion is trivalent, and the oxygen ion accepts two electrons. ActuallyMcan also be divalent iron, forming magnetite (Fe3O4). The crystal structu...
