while a broad optical absorption peak from 500 to 1000 nm (peaking at 700 nm) emerged and intensified, suggesting the intervalence charge transfer between Fe2+and Fe3+ 30, directly revealing the formation of the PB structure (Fig.3c). To monitor the ionic concentration during the cation...

Like bulk magnesium, they found that a self-limiting oxide layer formed around themagnesiumthat protected it from further oxidation without changing the material's plasmonic properties. That helped preserve the particles' characteristic shape, which remained stable even three months after synthesis and s...
The morphology and element distribution of samples were examined by transmission electron microscopy (TEM, Thermo/Tecnai G2 20, United States) and scanning electron microscope (SEM, Zeiss/Sigma300, Japan). The structure of materials was characterized by X-ray diffraction (XRD, Bruker, D8 ADVANCE,...
These films display a dual-layered structure similar to that of the AE81 M + 0.5%Ca alloy, consisting of an inner layer enriched with fluorides and an outer layer predominantly containing oxides. The oxide film of AE81 M + 2%Ca, which exhibits a similar structure, is not shown here for...
The Mg1.1Mn6O12 center dot 4.5H(2)O named as magnesium octahedral molecular sieves (Mg-OMS-1) owns nanobelt structures as a cathode material for aqueous magnesium-ion battery. The morphology and structure of Mg-OMS-1 are measured by X-ray diffraction, scanning and transmission electron ...
Crystal Structure of a New Acentric Oxide Fluoride of VIV: BaVOF4 The structure of BaVOF 4 has been determined by X-ray diffraction data from a single crystal obtained by hydrothermal synthesis: S.G. Fdd2 (acentric), Z =... MP Crosnier-Lopez,H Duroy,JL Fourquet - 《Zeitschrift Für...
residual porosity was the result of a disturbed flow of the shielding gas that transferred contaminants from magnesium vapour onto the melted layers. Other authors [81] established that such contaminants deposited on the powder surface in the form of oxide layers might result in weak interlayer bond...
involved in H-2, D-2, and (H-2 + D-2 + HD) production, and found that adducts with hydrogen atoms (H-center dot) were not obtained from the spin-trapping reaction between 5-(2, 2-Dimethyl-1,3-propoxy cyclophosphoryl)-5-methyl-1-pyrroline N-oxide (CYPMPO) and the MgCC material...
In particular, the Fe particles are mainly located in the light areas of image, while the dark zones are composed of magnesium oxide (Figure 3a). As can be noticed by the observation of SEM (Scanning Electron microscopy) images (Figure 3b), the zones characterized by the presence of iron ...
