It is thus possible that a quinary σ phase containing Cr, Co, Fe, Mn, and Ni elements can also form. Moreover, despite being stable over different compositional domains, the lattice parameters of the reported binary Cr-X σ phases were very comparable due to the similarity in their atomic...
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 ...
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 ...
In addition, the rod-like TMn phases that form during solution treatment in the Mn- containing alloys are non-shearable, which enhances the yield strength by the Orowan looping. The CRSS induced by the TMn phase can be expressed as follows [45,46]: ∆τ = √Gb 2π 1 − · 1 ·...
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 (...
At 950 °C, austenitic grains transform into equiaxed grains with uniform size, and some grains form banded annealing twin crystals. FFigiguurree44. .MMicircor-os−tsrutrcutuctrueroefo2f8M28nM-1n0−A10l Acolldco-rlodl−lerodllaendneaanlneedatleesdt stetesetlsatenenleaanlendeaalte9d50at...
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 ...
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...
These chains are further connected by HL− ligands to form a 3D coordination network. Interestingly, both the hydroxy and the carboxylate groups of the ligands are deprotonated and coordinated to the metal centres, whereas the pyridyl group is protonated and uncoordinated, although it partic- ipa...
