The aryl group is a functional group that is derived from an aromatic hydrocarbon. They are basically aromatic ring compounds missing a single hydrogen atom. The single hydrogen deficiency makes these groups capable of bonding with another carbon chain. Figure 1 shows the general structure of aryl...
In some cases, R1 is directly bonded with phosphorus and R2 with an oxygen or a sulfur atom (phosphonates or thionphosphonates, respectively). In phosphoramidates, either R1 or R2 or both are attached with mono or di-substituted amino groups. In all the OP compounds, the X group is ...
The square-planar structure was found to be more than 3 eV lower in energy than a proposed quasi-octahedral structure. The relative energies of the square-planar and other structures for a series of nine-atom alkali halide cluster ions are found to correlate with published experimental data....
Aqueous redox flow batteries with halide-based catholytes (where the halogen atom (X) is Br or I) are promising for sustainable grid energy storage. However, the formation of polyhalides during electrochemical charging and the associated phase separation into X2 limits the operable state of charg...

(Fitting parameters shown in Supplementary Table1). In addition, the emerging peak atca. 1.4 Å and 2.5 Å can be attributed to Pb-N and Pb-Zn pairs formed at the interfaces. The formation of new atom pairs was supported by the X-ray adsorption near-edge structure (XANES) of ...
(1.40, 1.03, and 0.75 eV respectively at PBE), so that spin mixing due to the conduction-valence band mixing is reduced at lighter halogen compound, which usually weakens the spin-phonon interaction; (ii) The lighter halogen atom reduces the SOC strength of the material (weaker SOC ...
