The fairly close weights of the 3d orbital on the Ni centre and the 1s orbital on the hydride ligand suggest the covalent nature of the Ni–H bond. However, the larger weight of the d-orbitals than the 1s orbital in the LUMO+12 as well as the LUMO+1 and the remarkable bulge on ...
In this work, by means of density functional theory (DFT) computations, we first confirm that the ppC molecule Be9C24 À is a local minimum on the potential energy surface. Based on the structural characters of Be9C24 À , we design a ppC-containing 2D material, namely Be5C2 ...
The term “active site” used in the first embodiment means a site at which charges are transferred within the enzyme. For example, the active site is a redox center or a site receiving charges from the redox center. The redox center includes the following two concepts. One type of re...
