Wormlike micellar solutions are composed of long flexible structures that result from self-assembly processes of surfactant molecules. At high enough concentration, these wormlike micelles can entangle and give viscoelastic properties to the solution just like typical polymers. Micellar solutions, in contrast to polymeric solutions, have two different relaxation mechanisms. One is the reptation...

It was shown by the conductometric study that formation of micelles in cetyltrimethylam¬monium bromide (CTAB) – dimethylsulfoxide (DMSO) water system occurs at higher critical micelle concentrations (CMC) than CTAB system. The solubilization nitroxoline this upon reaching CMC determined spectrophotometric method. Box–Behnken design used to obtain systems with highest light absorption nitroxolin...

Scavenger receptors (SRs) like cluster determinant 36 (CD36) and SR class B type I (SR-BI) play a debated role in lipid transport across the intestinal brush border membrane. We used surface plasmon resonance to analyze real-time interactions between the extracellular protein loops and various ligands ranging from single lipid molecules to mixed micelles. Micelles mimicking physiological struct...

Phenolic derivatives are among the most important contaminants present in the environment. These compounds are used in several industrial processes to manufacture chemicals such as pesticides, explosives, drugs and dyes. They also are used in the bleaching process of paper manufacturing. Apart from these sources, phenolic compounds have substantial applications in agriculture as herbicides, ins...

Studies have been carried out to determine the maximal solubilization of cholesteryl oleate and tocopheryl acetate within mixed bile salt-fatty acid micelles and to establish reproducible assays for pancreatic esterase activity using these micellar substrates. At pH 8.5, using 30 mM sodium taurocholate and 10 mM oleic acid, reproducible micellar solutions of the esters could be prepared giving ...

In this work, different cationic surfactants with various aliphatic and aromatic ammonium cations were used to prepare inhibitor coatings characterized by techniques such as IR spectroscopy NMR. The prepared electrografting on the steel surface their anticorrosion properties evaluated in media (HCl, H2SO4 NaCl solutions). electrochemical potentiodynamic polarization technique was study inhibiti...

The kinetic studies for copper-catalyzed homocoupling phenylboronic acids (1a-d) have been successfully carried out in an aqueous micellar medium under environmentally benign conditions (water as a solvent, micelle to help solubilize hydrophobic adducts) this study cetyl trimethyl ammonium bromide (CTAB ) is used surfactant produce micelle. Using different copper salts and complexes catalysts m...

The regulation of expression of the intestinal low density lipoprotein (LDL) receptor by luminal (apical) sterol flux was investigated in the human intestinal cell line CaCo-2. Cells were cultured on semipermeable micropore filters, which separated an upper and lower well. To the apical media were added solutions containing either taurocholate micelles alone or micelles containing sterols. Beca...
