Sentence examples for increasing electron density from inspiring English sources
The protonation reaction was facilitated owing to the increasing electron density of the azo group, due to the donating effect of the hydroxyl group at the ortho position.
The cell performance maximum through increasing electron density at counter electrode surface to enhance its catalytic ability is still a challenging problem.
For polarization Coulomb field scattering, the electron mobility rises with the increasing electron density, but it decreases for the LO phonon scattering and the interface roughness scattering [6, 9].
Its intensity (Figure 2) presents an abrupt increase at 0.85 V which is consistent with the increasing electron density accumulated at the 2DEG just after the resonant tunneling condition.
A probable explanation for this effect might be the use of PVP as stabilizer, which has the ability to donate electron to the vacant d-orbital of metal atoms, hence leading to Pt Pt bond expansion of the surface-near atoms by increasing electron density [2, 22, 47].
This is supported by model calculations of the greenhouse gas effects on foF2 because hmF2 closely follows the boundary between the increasing electron density below and decreasing electron density above, only a small trend in foF2 is expected (e.g., Qian et al. [2009]).
As in alkenes, the π bonds constitute regions of increased electron density lying parallel to the carbon-carbon bond axis.
A π bond forms a region of increased electron density because the electron pair is more distant from the positively charged carbon nuclei than is the electron pair of the σ bond (see chemical bonding: The quantum mechanics of bonding).
These lower wave number shift from the pure citrate ions and nitrate-LDH suggest the increased electron density around the functional groups.
Moreover, thiophenes that could be considered refractive to HDS, are readily oxidized because of their increased electron density on the sulfur atom [48].
Furthermore, the increased electron density caused by the Ta-doped TiO2 improves the fill factor of the solar cell.
