In this study we investigated resveratrol (trans-3,5,4'-trihydroxystilbene) solubilization with sodium 3α,12 α-dihydroxy-7-oxo-5 β-cholanoate (S7-OD) and sodium dodecyl sulfate (SDS). The investigation was aimed at determining whether large spherical micelles (SDS) or small longitudinal micelles (S7-OD) are more convenient for incorporation of resveratrol. Also, we studied resveratrol behavior ...

Vibrational sum frequency generation spectroscopy is used to study the interactions of the charged soluble organic surfactant sodium dodecyl sulfate (SDS) with an insoluble 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) monolayer at the air-aqueous interface. Results indicate that the surfactant species compete for surface sites in the mixed system, with a lower monolayer number density of ...

In this research, the influence of additives on rheological and sedimentary properties magnetorheological fluid (MRF) was tested analyzed. The were stearic acid, sodium dodecyl sulfate (SDS), their mixture, respectively. MRF composed carbonyl iron particle, silicone oil, liquid paraffin, graphite bentonite, SDS. results indicated that mainly influenced by mass fraction particle. When fractions ...

Surfactants are chemicals that adsorb to the interface between a solution and another phase (gases or solids) self-assemble molecular clusters known as micelles in (water oil phase). Measurements of surface tension sodium dodecyl sulfate (SDS) distilled water at 298.15K reported. The increase concentration then decreased 298.15K. Critical micelle (CMC) with decrease tension. graphs versus were ...

Development of catalysts for the selective hydrolysis proteins is challenging, yet important many applications in biotechnology and proteomics. The hydrophobic particularly as due to their poor solubility, use surfactants often required. In this study, proteolytic potential catalyst systems based on Zr(IV)-substituted Keggin polyoxometalate (Et2NH2)10[Zr(PW11O39)2] (Zr-K 1:2) three different (i...

Impinging dilute sodium dodecyl sulfate (SDS) droplets on micropillar-arrayed polydimethylsiloxane surfaces were experimentally investigated. It was found that the behaviors of impinging greatly depend surface roughness and SDS concentration. Similar to pure water droplets, there exists a narrow range dimensionless Weber number, We, for complete rebound impacting droplets. The lower upper limit...

Two agro-based anionic surfactants containing an isosorbide moiety have been synthesized and their amphiphilic properties evaluated. Since isosorbide is now considered as an important platform chemical of the starch industry, these compounds could represent bio-sourced alternatives to the alkyl ether sulfates (notably lauryl ether sulfate, LES) that are based on petroleum-derived ethylene oxide...
