2b). As this excitation disappears above TN it must originate from spin-waves meaning that the total energy results from the sum of all magnetic contributions such that S(Q,ω) ≈ D + 2J + 4J′. Simulating the spin-wave features (overlay plot in Fig. 2b), taking into account energy ...
The Fourier Transform of the EXAFS spectra confirm the oxidic nature of the Ni phase in all catalysts as identified by XANES, with major contributions from Ni-O and Ni-Ni (oxide 2nd shell) at 2.0 and 2.9 Å, respectively in Table 1. Furthermore, the absence of a significant scatter at...
School of Materials, The University of Manchester, Manchester, M13 9PL, UK Liang Qiao Contributions C.L. conducted the TEM analysis and is the main author for this paper; T.Y. and F.Z. provided assistance in TEM sample preparation; J.K. and Y.Z. conducted the ion beam irradiation and...
To obtain insight into the origins of the structural signatures of the first coordination shell, calculated EXAFS spectra of M-N4, M-N3-O, M-N2-O2, M-N-O3, M-O4, and M-N4-O2 (O2molecule adsorbed atop the metal center) configurations were employed for comparison with the experimental re...
The optical band gaps of the nickel(II), copper(II) and zinc(II) complexes were found to be 1.91, 2.50, and 1.96 eV, respectively, which means that they can be employed as semiconductors and that they are in the same range as highly effective photovoltaic materials. The Urbach energy ...
In order to improve the resistance to metal sintering, many strategies were applied to improve the Ni dispersion and different methods of catalyst preparation have been investigated, such as evaporation-induced self-assembly, core-shell, and sol-gel, to limit the Ni crystallite growth [6,7,8,9...
Another Kural points that the foundation for all good things to happen in life solely lies on the integrity and self discipline we hold. This can also be described as Character. We have often heard” Wealth is lost, nothing is lost; health is lost something is lost; but if character is...
So basically, we have a democracy where election success tends to be purchased with campaign contributions. In other words, we have a corrupt democracy. But we all know this, and we allow it anyway. We consider this corrupting money (and the influence it purchases) a necessary evil of ...
