For the hard network, the higher bond energy is responsible for the stiffness of the hydrogels, while the dynamic [Fe.sup.3+] and -CO[O.sup.-] coordination bonding provides self-healing properties by reversible dissociation and re-association.
The 532nm wavelength corresponds to a photon of energy 2.33eV, so the energy of two photons is 4.66eV, just within the range of the C-H bond energy (4.3-4.85eV) in CH4.
We forecast few additional defaults for the rest of 2018, with the high-yield bond energy sector default rate declining to 2% for the year, in line with that of the total high-yield universe, and the leveraged loan energy sector default rate falling to 11%.
Taking into account the hydroxyl groups are shared by the octahedron edges, the presence of divalent or trivalent cations in one or more vicinal octahedron can change the bond energy of the hydroxyl groups in lamellae surface and these aspects were also inferred in above mentioned work [38].
The bond energy is estimated as the difference in the energies of the two fragments and the entire molecule.
Generally, bond length of chemical bond is inversely proportional to the bond energy: the more low bond energies, the more crack of chemical bond.
When the conversion rate was low, the functional groups of weaker bond energy were decomposed into oil and gas, while those with higher bond energy were broken up and produced most of the tar, though at higher temperatures and with higher energy.
It is clear from this Fig that pure Si dots show high binding energy per silicon atom compared to the pure Ge dots as would be expected on the basis of the relative bond energy, whereas mixed dots are somewhere in between.
So the average bond energy for per surface area of the unit sphere (Fig.
Moreover, in recent years bond energy calculation has been applied in estimation of surface properties through (atomic scale) broken bond model; thus the bond strength should be known between different neighboring atoms.
In fused silica, the stability of total glass network cannot be considered only with the change of single bond energy. A strain of one bond will influence the structural stability of glass network in a certain area.
where V is the potential energy when the distance of two atoms is r, [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is the equilibrium distance between the atoms, and [epsilon] is the bond energy at the equilibrium distance.
