alloy, known as the Cantor alloy, exhibits a single face-centered-cubic (FCC) solid solution (space group Fm-3m and lattice parameter a = 3.3605 Å), high ductility (50–60%), reasonable strength (yield strength = 160 MPa), and toughness (>217 MPa m1/2) at room temperature [13,14...
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 ...

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 ...
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 ...
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...
In these circumstances, Equation (1) can be viewed as the sum of the following two equations that show the contributions of n1 and n2, which represent the number of hydrogen atoms in the first and second types of sites, respectively: M+ n1 2 ↔ M1 Hn1 M+ n2 2 ↔ M2 Hn2 (16)...
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...
