Additive and nonadditive surface tension components and the interpretation of contact angles
TL;DR: In this paper, it was shown that the relation between contact angles and the three controlling parameters ybw, yg, and 7s of a polar solid, S, cannot be established by means of one single equation.

Abstract: It is demonstrated that, while the Lifshitz-van der Waals (rLW) and the polar, Lewis acid-base (rAB) surface tension components are additive, the Lewis acid-base electron-acceptor (7') and electron-donor (y-) surface tension parameters (which on account of the intrinsic asymmetry of their interactions are connected in a more complex manner) are not additive. Contact angle data cannot, in general, be correlated with a single surface tension property. The relation between contact angles and the three controlling parameters ybw, yg, and 7s of a polar solid, S, cannot be established by means of one single equation. These three unknowns can, however, be determined by means of contact angle measurements with three different liquids L (of which two must be polar and H-bonding), which are completely characterized as to their respective rkw, yL+, and y i parameters by using a modified Young-Good-GirifalcoFowkes equation 3 times. In view of these considerations. recent claims to have proven the applicability of a single "equation of state" are shown to be spurious.

Electrokinetic effect and surface free energy behavior in the adsorption process of a reactive dye onto Leacril pretreated with polyethyleneimine ion.
TL;DR: The results obtained suggest that the interaction between the amine group of the PEI previously adsorbed and the reactive beta-sulfato-ethysulfonylgroup of the dye can be responsible for the improvement in dye uptake.

Changes on the physico-chemical surface properties and adhesion behaviour of Enterococcus faecalis by the addition of serum or urine to the growth medium
TL;DR: In this article, the authors used a parallel plate flow chamber set at 37°C to simulate the conditions of flow inside the human body to characterise the surface of Enterococcus faecalis ATCC29212 through hydrophobicity, surface free energy and zeta potential.

Homogeneously and gradually anchored self-assembled monolayer by tunable vapor phase-assisted silanization
TL;DR: In this paper, a straightforward grafting approach in the vapor phase was developed in view of preparing alkyl self-assembled monolayers uniformly or gradually anchored onto silica surfaces, as demonstrated by wettability and XPS measurements.
