solvation

sol·va·tion

(sol-vā'shŭn),
Noncovalent or easily reversible combination of a solvent with solute, or of a dispersion means with the disperse phase; if the solvent is water, solvation is called hydration. Solvation affects the size of ions in solution, thus Na+ is much larger in H2O than in solid NaCl.

solvation

The interaction of solvent molecules with the molecules or ions dissolved in them.

The interactions occurring in different solutions can also be confirmed by the solvation number, which is measure of structure forming or structure breaking tendency.
17) and the extent of resin solvation of asphaltene aggregates may be fairly uniform.
4] solutions, which may be possibly attributed to solvation effect of potassium and ammonium.
In order to achieve a reliable model of the flap dynamics, a continuum treatment of water was employed, which accurately and rapidly included the effects of aqueous solvation but resulted in reduced viscosity and more rapid conformational changes.
The decrease in the value of 'r' with the increase in temperature may indicate that the reduced species are solvated, the extent of decrease in the value of 'r', is different at different pH values, may be due to the difference in the extent of solvation (Mehta et al, 1979).
The energetics would resemble the solvation of a polar substance (dions) in a solvent, with an additional force due to the applied electric field.
Formation of higher order structures are aided by non-covalent forces such as hydrogen bonding, hydrophobic stacking, solvation effects and electrostatic interactions.

For instance, a more polar polymer can be used to interact more favorably with a growing polypeptide by increased solvation of all the reactive sites.
Studies conducted on the water sorption of dental materials indicate that excessive water uptake may cause a decrease in mechanical strength, distortion, and depression of the glass transition temperature [25] due to plasticization, solvation, reversible rupture of weak inter-chain bonds and irreversible disruption of the polymer matrix [26].
The Solubility module covers a wide range of concepts: vapor pressure and solution equilibrium, molecular solvation, and factors affecting solubility, miscibility, dispersion, and colligative properties of solutions.
