These assumptions were based on electronic structure calculations using molecules in the gas phase without accounting for Fermi-level pinning as a result of the metal–thiolate bond. The energy level diagram shown in Fig. 1 is based on experimental data (Table 1) from which we conclude that ...
Energy level diagram showing the splitting of the free ion quartet states under the influence of a ligand field with Td (red lines) and D2d (blue lines) symmetries. The arrows depict the transitions observed in the MCD spectrum. B ¼ 653 cmÀ1, C ¼ 2,942 cmÀ1 and the AOM ...
Lithium-sulfur (Li-S) batteries hold great promise in next-generation high-energy-density energy storage systems, but the intractable shuttle effect and the sluggish redox kinetics of polysulfides hinder the prac-tical implementation of Li-S batteries. Here, heterostructured Fe3C-FeN nanoparticles ...
Top right: schematic representations of the chemical structures for the GO and GO-Cs used in the study. The white, red, and pink dots represent C, O, and Cs atoms, respectively. (b) Schematic energy-level diagram for the various layers of the optimized tandem device. (c) J-V ...

Calculations of complete energy level schemes for 4 f n and 4 f n 1 5 d 1 electronic configurations of free trivalent rare-earth ions have been performed. Semi-empirical Hamiltonian was used for the calculation of 4 f n configuration while a fully relativistic first-principles many-electron me...
Conventional desalination units though are designed to perform at an optimal level and to operate continuously at a constant rate. As comparison, in scenario 4, the energy consumption of such a desalination plant is integrated into the system as a secondary load. In this case, the secondary ...
The energy level diagram of a typical organic dye molecule has a singlet electronic state S0 as the ground state, with total spin quantum number zero, and a succession of higher excited singlet states labeled as S1, S2, S3—with decreasing energy separation between them. When the two electrons...
