C H Activation/Functionalization With Earth Abundant 3d Transition MetalsThe rapid development of CH functionalization reactions can be attributed to their direct synthetic approach and attractive atom-economy. Precious metal catalysis has been extensively studied and proven effective. In recent years, 3d ...
transition metalsMolecular syntheses largely rely on timeand labour﹊ntensive prefunctionalization strategies. In contrast, C–H activation represents an increasingly powerful approach that avoids lengthy syntheses of prefunctionalized substrates, with great potential for drug discovery, the pharmaceutical ...
The effects of partial substitution of these 3d transition metals for Co except for Cr in the layered NaxCo2O4 on thermoelectric properties were investigated. The electrical resistivity of these partially substituted samples significantly increased over the entire temperature range, as compared to the ...
The transition metals are the only class of solids studied whose cohesive energy is not closely approximated by this classical energy. This phenomenon is related to the near-degenerate nature of their groundstates. A simple algorithm for the calculation of the electrostatic energies in terms of ...
The defect formation energies of transition metals (Cr, Fe, and Ni) doped in the pseudo-H passivated ZnO nanowires and bulk are systematically investigated using first-principles methods. The general chemical trends of the nanowires are similar to those of the bulk. We also show that the format...
Magnetic Contribution to the Lattice Constant and Bulk Modulus of the Transition Metals and Alloys A comparison is made for the bulk modulus B and the shear moduli C and C' of several f.c.c. transition metals and alloys of the 3d series. The moduli of pa... N Môri - 《Bulletin of...
Multiple-scattering approach to the x-ray-absorption spectra of 3d transition metals The x-ray-absorption near-edge structure (XANES) has been calculated for the 3d transition metals Cr, Fe, Ni, and Cu from a multiple-scattering approach wi... M Kitamura,S Muramatsu,C Sugiura - 《Physical ...
The L23 near-edge fine structure has been investigated in electron-energy-loss spectra from thin films of 3d transition metals and an unexpected departure from the statistical L3/L2 "white-line" intensity ratio of 2: 1 is reported. For Ti, a ratio of 0.7: 1 is observed, while for ...
The ratio of CoIV=O reactivity via direct water (∼55 M) activation or via reaction with OH− (∼0.01 M at pH 12) is dependent on the reactant availability and reaction barrier. Download: Download video (98KB) Video S1. Visualization of the transition state for O–O bond formation...
