Hydrate formation and adhesion on low surface energy materials
… The presence of this liquid film depends on the spreading coefficient of cyclopentane on the solid in the presence of water. Through a systematic modification of the surface chemistry of the solid surface using two different silanes, we correlate the wettability of water and cyclopentane to the …

Effect of surfactants and brine salinity and composition on spreading, wettability and flow behavior in gas-condensate reservoirs
… to investigate the concept of modifying the spreading coefficient and wettability using low-cost surfactants in the near wellbore region, to prevent the gas flow problems associated with condensate buildup. This study also examines the effect of brine salinity and composition on wettability, …

Influence of surface tension and concentration of a non-ionic surfactant on the barrier effectiveness of a microporous polypropylene fabric for pesticide protective clothing
… absorbency test, a modified Draves test, the spreading coefficient (S<sub>c</sub>) values and, by inference, from a Zisman plot. As surfactant concentration increased, γ decreased, and then remained relatively steady past the 0.0134 percent concentration level, the critical micelle …

Synthesis of linear copolymers and of polymer brushes substituted with spiropyran groups : a step towards light driven molecular walkers
… This is explained by changes of the spreading coefficient, which enabled motion of the macromolecules on the surface.
