Objective The present paper investigates the effect of nanoparticle concentrations on interfacial tension and wettability during low salinity water flooding (LSWF) at microscale. Method A wide range LSW were prepared investigated for their ability to modulate with crude oil. impact fluid-rock interactions was studied through contact angle measurements water-wet, intermediate-wet oil-wet glass s...

A model is presented suggesting the interaction of CO(2) and bicarbonate on lipids of the cell membrane. The interfacial tensions between water and oil (benzene) phases were measured using the stalagmometer and the sessile drop methods. Effects of electrolyte solutions and of CO(2) on molecular arrangement at the interface were calculated. Chloride solutions against oleic acid in benzene produc...

The assembly and function of cilia on Caenorhabditis elegans neurons depends on the action of two kinesin-2 motors, heterotrimeric kinesin-II and homodimeric OSM-3-kinesin, which cooperate to move the same intraflagellar transport (IFT) particles along microtubule (MT) doublets. Using competitive in vitro MT gliding assays, we show that purified kinesin-II and OSM-3 cooperate to generate moveme...

Ferula gumosa  Boiss is one of the natural plants of Iran whose exudates (Barijeh) can be used in food industry. In the present study the properties of the gum extracted from tubers of Ferula gumosa were examined. For this purpose, gum was extracted from crude exudates by alcoholic extraction with 90% (v/v) ethanol. The purity of gum was relatively high, and it was composed mostly ...

The physicochemical parameters of tris(2-methylbutyl) phosphate (T2MBP), a molecule possessing the essential characteristics required to be considered as promising extractant in solvent extraction stage fast reactor fuel reprocessing, have been evaluated present study. In this context, density, viscosity and interfacial tension (IFT), which are few among important selection criteria prior its d...

Abstract The use of nanoparticles (NPs) can considerably benefit enhanced oil recovery (EOR) by changing the wettability rock, improving mobility drop, and decreasing interfacial tension (IFT) between water. Prior to application in fields, it is essential conduct measurements at laboratory scale. However, estimation reservoir difficult most experiments. Practicably, ZnO NPs were used modify roc...

The test-area (TA) perturbation approach has been gaining popularity as a methodology for the direct computation of the interfacial tension in molecular simulation. Though originally implemented for planar interfaces, the TA approach has also been used to analyze the interfacial properties of curved liquid interfaces. Here, we provide an interpretation of the TA method taking the view that it c...

Lecithin-rich mixtures of the nontoxic surfactants lecithin and Tween 80 are effective marine oil spill dispersants, but produce much higher oil-water interfacial tension than other, comparably effective dispersants. This suggests interfacial phenomena other than interfacial tension influence lecithin-Tween 80 dispersants' effectiveness. The interface between seawater and dispersant-crude oil m...

Cadherins are transmembrane proteins that mediate cell-cell adhesion in animals. By regulating contact formation and stability, cadherins play a crucial role in tissue morphogenesis and homeostasis. Here, we review the three major functions of cadherins in cell-cell contact formation and stability. Two of those functions lead to a decrease in interfacial tension at the forming cell-cell contact...
