Charge deformabilities

Electrostatic interactions between a spherical charged protein particle and an oppositely charged, deformable interface can be estimated by evaluating the electrostatic force on a small segment of the interface as that produced by an adjacent flaf section on the protein surface. The strength of this interaction is dependent on the separation distance (b) between those two segments, and so will be a function of the position of the interfacial segment ... [Pg.153]

However, adsorption is a complex process that cannot be described by only one parameter. Thus we developed an isotherm for adsorption of ions that included most of the parameters already described (Section 6.8.13). It included heterogeneity of the surface, displacement of solvent molecules from the electrode, transfer of charge, deformation of the adsorbing ions, ion size, lateral interactions, etc. [Pg.248]

Polarizability is a measure of the ability of an ion s electron cloud to be deformed by nearby charges. Deformation of the electron cloud induces a dipole in the ion. The attraction between the induced dipole and the nearby charge increases the binding of the ion to the resin. [Pg.592]

It is important to note that similar beneficial mixing flows and solid polymer particulate charge deformations to those discussed earlier also occur in the multilobal variants of the counterrotating, intermeshing TSEs, as well as in CMs. We used the co-rotating, fully intermeshing twin screw kneading element pairs, because the relentless expansion/ contraction cycles can best be demonstrated with them. [Pg.532]

Dungan and Hatton [12] solved Eq. (6) together with Eq. (48) for the problem depicted in Fig. 6, where a spherical particle is interacting with an oppositely charged deformable interface. To obtain their solution they used a boundary-integral method, in which the surfaces of the interface and sphere are discretized and assigned constant surface charge density boundary con-... [Pg.267]

In the d o case of a singly-occupied metal d-orbital interacting with a doubly occupied ligand orbital (which in general will be a synnetry-adapted linear combination of atomic orbitals, see Table VI) the charge deformation can be written as (21) ... [Pg.54]

The existence of an electric quadrupole interaction is one of the most useful features of Mossbauer spectroscopy. The theory is closely related to that used in nuclear quadrupole resonance spectroscopy [14, 15). Any nucleus with a spin quantum number of greater than / = 4 has a non-spherical charge distribution, which if expanded as a series of multipoles contains a quadrupole term. The magnitude of the charge deformation is described as the nuclear quadrupole moment Q, given by... [Pg.54]

The inclusion of covalency and charge deformation is physically reasonable, while the potential parameters are still determined empirically. Moreover, increase of the number of parameters causes arbitrariness in their determination. Now we need to revise the interatomic potential from a different standpoint apart from experimental observations. [Pg.202]

The very same charge deformability of the mixed-valence Sm ion due to 4f" - 4f"5d excitations used for the description of the Raman intensities in fig. 37 has been used to describe the phonon anomalies (Bilz et al. 1979). Therefore we can conclude that the dominant F scattering intensities of Sm 25S near 250 cm" and 85 cm , respectively, arise mainly from the LO and LA phonon anomalies in the [111] direction, emphasizing scattering from L-point phonons. The available data on the LO(L) phonon frequencies of RS are depicted in fig. 38 as a function of the lattice parameter. The LO(L) phonons of intermediate-valence metallic SmS and Sm jY 25S lie between the divalent reference line given by YbS and EuS, and the trivalent reference line spanned by YS, GdS, PrS and LaS, thus exhibiting the behavior of an alloy of divalent and trivalent Sm ions. Figure 39 shows the bulk modulus of several RS compounds at room... [Pg.204]
