5have led to studies of effective ways of utilizing these molecules for synthesis of value-added chemicals. The catalytic reduction of CO2by light alkanes (methane, ethane, propane, etc.) has been the subject of many investigations due to its promising role in mitigating CO2emissions...
Due to a strong Coulomb coupling in the V(2 +)-O(2 −) pair (Frenkel pair), the ion-vacancy separation requires a sufficiently high electric field in the oxide, unless the positive charge is instantaneously compensated for by a capture of an injected electron (a relatively low probability...
The cooperativity was found in these complexes because their interaction energies are stronger than the sum of the pair interaction energies. The electrostatic force was believed to be the main net contribution to the stability of these complexes. The simultaneous interactions involving CO2, CO and ...
Earlier formulas for the electron‐pair bonding energies of methane, and radicals derivable from methane, are combined with recent data on the energy levels of the carbon atom, the heat of sublimation of carbon, the energy for removal of the first hydrogen, and the dissociation energy of CH to...
We present a novel paraphrase fragment pair extraction method that uses a monolingual comparable corpus containing different articles about the same topics... W Rui,C Callison-Burch - Workshop on Building & Using Comparable Corpora: Comparable Corpora & the Web 被引量: 45发表: 2011年 Deactivation...
The lone pair of −OH involved in the hydrogen bond with the adjacent μ3−OH group is consequently weakened. These calculations were made on Al7O8H50 (above) and Al7O8H6+ (below) clusters using crystallographic distances using a cluster embedding technique at the B3LYP/6-311G(d,p) ...
Arrange the strengths of the bonds below: lone pair, single bond, double bond, triple bond. Why is bond strength in CN^- stronger than the bond strength in B_2? What types of covalent bonds are present in a triple bond? a) Put the followi...
