This "hydrophobic interaction" is much stronger than the expected van der Waals interaction at distances below 8 nm and decays exponentially with distance. The results highlight the long-range nature of hydrophobic (solvation) forces and indicate that these forces may determine the magnitude of the...
of this hydrophobic interaction has not been fully explained at this time. Addition of salt changes the range of the forces, and this provides a clue to the mechanism. Electrolyte correlation effects can be ruled out, as any force would depend exponentially on the Debye decay length, and this...
an interaction not observed in the KRASWTstructure. The Lys16G12Vside chain had a similar electrostatic interaction with Asp116 to Lys16WT, but its C terminus was not anchored by multiple residues on α1 and α2 of HLA-A*03:01 as in the KRASWT...
interaction energy decays as the distance between water and the confining surface increases. When the drag force vanishes, the velocity profile is parabolic. As one of the main findings of this study, it is revealed that the drag of water flow at the first water layer corresponds to an increa...
In order to quantify interaction times, we count the time elapsed within a threshold distance of 1 nm corresponding to the typical range of van-der-Waals forces. We find that the average interaction time between lecithin and the RBD is on the order of hundreds of nanoseconds. As expected, ...

and regularly ensures a high surface area contact between strands. I.e., even though fluorine holds its electrons tight, the fact that everything is crammed so close together in PTFE greatly increases the frequency of transient dipole interaction, and thus gives rise to a high melting ...
(an exponential distance-dependence for the interaction had previously been proposed by Marcelja et al., 1977). Based on these findings, it was proposed that for small solute molecules the hydrophobic pair-potentialwH(r) is exponential, proportional to the diameter of the molecules or molecular ...
There are some important differences between interaction energies among identical entities, when immersed in water (ΔGiwi) and interaction energies among different entities, also in water (ΔG1w2). These are especially striking in the hydrophobic attraction of quite hydrophilic molecules by low energy...
The inorganic salt referred to in the "Summary of the Invention" is included in the polymer-forming solution to increase the hydrophobic interaction between the hydrophobic groups on the polymer, and thereby enhance the precipitation of the polymer. This effect is known in the art as the "saltin...
