The complex H2Os3(CO)11, undecacarbonyldihydridotriosmium, has been studied by a single-crystal x-ray structural analysis. The complex crystallizes in the centrosymmetric monoclinic space group P21/n with a = 8.0744 (16) , b = 14.7265 (2... MR Churchill,BG Deboer - 《Inorganic Chemistry...
This suggests that they were influenced by similar source complexity and the 3D structure of the crust and upper mantle. The ray paths of PcP and PKiKP deviate substantially in the lower mantle, especially at the bottom of the mantle, and spatial separation between PcP and PKiKP sampling ...
The molecular structure shows the absence of intramolecular stacking in the crystalline state, as indicated by earlier 1H NMR analysis in solution. In addition, the crystal packing reveals the formation of a layered structure, due mainly to intermolecular N—H?O=C hydrogen bonding and arene–arene...
Zinc nitrate precipitated with NaOH solution under double-jet conditions produced uniform nanostructured zinc oxide particles containing stacked nanoplates at 80 °C in the presence of starch sodium octenyl succinate (SSOS). In the absence of SSOS, nonuniform agglomerated ZnO particles and hexagonal na...
This invention provides a multilayered structure comprising a substrate layer secured to a layer comprising a composite of a polymer and a particulate, layered compound selected from the group consisting of compounds represented by the general formula M(O3ZOxR)n wherein M is selected from the ...
Electronic structure. At their appearance above 4 GPa all new octahedral layered phases are indirect gap semiconductors. The values of GGA band gaps at 10 GPa for the investigated phases, of order 2 eV, are given in Supplementary Table S1. At 30 GPa, the gaps close and ...
(ii) a multi-layer approach produces a connective structure consistent with most real-world networks (e.g. sparse, inhomogeneous, and clustered); and (iii) the multi-layer network is a multiplex that preserves the main connective features of its constituent layers due to positively correlated ...
形成于长期俯冲环境下的镁铁—超镁铁质岩体往往来源于交代的岩石圈地幔,如扬子北缘随枣盆地中周庵岩体(~637 Ma)的全岩Sr-Nd-Os同位素组成表明该岩体来自交代富集的大陆下岩石圈地幔(subcontinental lithospheric mantle),被认为不利于形成铜镍硫化物矿床[15]。而形成于地幔柱和造山后伸展环境的镁铁—超镁铁质岩体...
Rational design of intergrowth P2/O3 biphasic layered structure with reversible anionic redox chemistry and structural evolution for Na-ions batteries Layered oxides have attracted unprecedented attention for their outstanding performance in sodium-ion battery cathodes.Among them,the two typical candidate......
The crystal structure is made up of corrugated layers consisting of square-planar (PdSe4)2- units [43], which is shown in Fig. 1, connected via common corners, and the interlayer force is van der Waals force. The phase diagram of Pd Se system is recreated from the data in reference ...
