Transition metalsalso exist in a 1:1 stoichiometric phase with boron (Fig. 6A). But the boron chains here show bending with bond angles 110 degrees indicative of sp3hybridized B Bsingle bondsand have identical bond lengths of ∼1.7Å which are much larger.48Metal-metal distances are also...
In this work, connectivity indices are used for the first time to predict the physical properties of a homogeneous catalyst. The existence of multiple oxidation states for transition metals requires a reformulation of the original equations for these indices. Once connectivity index descriptors have ...
Transition metals represent very interesting materials in which one can fairly readily analyze trends in their properties along the transition series. Although there have been recent calculations of their bulk and surface properties in the local-density approximation, our discussion here will be mainly ...
(MX2) of transition metals (M = Mo, W, Ni, etc.) and chalcogens (X = S, Se, Te) exhibit various electronic and optical properties5,6,7,8. The electronic and optical properties of TMD-QDs are usually explained by the combined mechanism of the quantum confinement effect, ...
Ideally, any metal-mediated process should be fast, clean, efficient, and selective and take place in a catalytic manner. These criteria are especially important considering that many of the transition metals employed in catalysis are rare and expensive. One of the ways of modifying and ...
Their characterizations have been done by elemental analysis, conductance data, magnetic susceptibility measurements, 1 H NMR, electronic, IR, ESR and X-ray studies. Ligand field parameters of some of the complexes have also been calculated. On the basis of spectral studies, the被引量: 1 ...
In this study, we have investigated several catalytic reactions on some transition metal surfaces, using density functional theory. All the reaction barriers have been determined. By detailed analyses we obtain some insight into the reaction barrier. Each barrier is related to (i) the potential ...
