Raman and FTIR spectroscopy methods also recognized the iron-associated presence of the organic component in the samples in the form of compounds with an aliphatic part (based on the significant contribution from methyl and methylene groups); compounds with double bonds, including benzene rings (...
Temperature's Effect on n1, n2, and n The number of sites available for hydrogen storage in hydride form and temperature have a complex relationship that depends on the particulars of the hydride material. The statistical physics model proposed for modeling the hydrogen storage in MmNi4.2Mn0.8 ...
This method enhanced the Li+ ions' ability to form a layer between the metal oxide layers and improved the performance of the lithium-ion battery. The SEM image showed that the NMA particles were well formed and did not show much agglomeration. NMA 973 had the best high-rate performance ...
With the convergence of the value for x, the site occupancies were fixed, and the displacement parameters were allowed to refine while restraining their values to be both similar and approximately isotropic (SIMU and ISOR instructions). Powder X-ray diffraction (PXRD) experiments were performed ...
Initially, the raw materials were heated to 750 ◦C to form a melt and kept for 40 min until completely melted. The melt was then cooled to 700 ◦C, and Al–10Mg ingot was added and stirred for 10 min. After that, the temperature of the melt was raised to 730 ◦C, and a ...
At 950 ◦C, austenitic grains transform into equiaxed grains with uniform size, and some grains form banded annealing twin crystals. MMeteatalsls22002244, ,1144, ,4x7 FOR PEER REVIEW 5 of 17 5 of 17 Figure 3. XRD pattern of 28Mn10Al cold−rolled annealed test steel annealed at 950 ...
When the atomic radii of two elements are similar, they are more likely to form metallic or covalent bonds, and electronegativity is a measure of an element’s ability to attract electrons in a chemical bond. The VEC number is valuable for predicting the crystal structures of compounds. ...
As shown in Figure 1, researchers have established single-phase solid solution and multi-phase composite models, respectively, for the existence of LiMO2 and Li2MnO3 phases in the form of layered single-phase solid solution [76–79] or multi-phase composite [61,80]. The main dispute ...
In nine structures, the ligand is present as the enol (O-H) tautomer, whereas only in four structures, it presents its keto (N-H) form (Table S1). In the literature, there are some examples of metal complexes with 6-OHpicH with both transition metals and lanthanoids, and most of ...
XPS results of three doped elements (Co, Cr and Al) in these two samples are very close (Figure 6d–e), which proves that the valence state and existing form of these three dopants are very stable in the synthesis process, and have good compatibility with the spinel structure LiNi0.5Mn...
