On April 14, 2020, Girard, Henri-Louis; Bourrianne, Philippe; Chen, Dayong; Jaishankar, Aditya; Vreeland, Jessica L.; Cohen, Robert E.; Varanasi, Kripa K.; McKinley, Gareth H. published an article.Formula: C10H22S The title of the article was Asphaltene Adsorption on Functionalized Solids. And the article contained the following:
Asphaltenes, heavy aromatic components of crude oil, are known to adsorb on surfaces and can lead to pipe clogging or hinder oil recovery. Because of their multicomponent structure, the details of their interactions with surfaces are complex. We investigate the effect of the physicochem. properties of the substrate on the extent and mechanism of this adsorption. Using wetting measurements, we relate the initial kinetics of deposition to the interfacial energy of the surface. We then quantify the long-term adsorption dynamics using a quartz crystal microbalance and ellipsometry. Finally, we investigate the mechanism and morphol. of adsorption with force spectroscopy measurements as a function of surface chem. We determine different adsorption regimes differing in orientation, packing d., and initial kinetics on different substrate functionalizations. Specifically, we find that alkane substrates delay the initial monolayer formation, fluorinated surfaces exhibit fast adsorption but low bonding strength, and hydroxyl substrates lead to a different adsorption orientation and a high packing d. of the asphaltene layer. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Formula: C10H22S
