We studied the phase behavior and aggregation in mixed aqueous solutions of the anionic UV-absorber 2-phenylbenzimidazole-5-sulfonic acid sodium salt, PhBSA (Na salt), and the cationic surfactant cetyltrimethylammonium bromide, CTAB. The mixtures of the two components behave similarly to catanionic surfactant mixtures. The samples on the PhBSA-rich side have low viscosity and are turbid. The tu...

Surface tension, density and conductivity measurements were carried out for systems containing mixtures of cetyltrimethylammonium bromide CTAB) and p-(1,1,3,3-tetramethylbutyl)phenoxypoly(ethylene glycol), Triton X-100 (TX100). The obtained results of the surface tension meaurements were compared with those calculated from the relations derived by Joos, Miller and co-workers. From the compariso...

Chromo-fluorogenic detection of GSH versus cysteine in water was accomplished using a pyrylium-stilbene derivative and CTAB micelles.

Self-assembly in mixtures of two single-chain cationic surfactants, with different tail lengths (CTAB and DTAB) as well as of a single-chain (DTAB) and a double-chain (DDAB) cationic surfactant, with identical tail lengths, have been investigated with small-angle neutron scattering (SANS) and rationalised in terms of bending elasticity properties. The growth behaviour of micelles with respect t...

Here, five different capping agents’ polyethylene glycol (PEG), cetyltrimethylammonium bromide (CTAB), polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), and oleylamine (OAm) are used to form copper nanoparticles (Cu-NPs), along with their electrocatalytic oxygen evolution reaction (OER) properties. The produced Cu-NPs’ mono-dispersity interactions PEG, CTAB, PVA, PVP, OAm were examined. mean...

Chromium ions released into aquatic environments pose major environmental risks, particularly in developing countries. Here, a low-cost N-cetyltrimethylammonium bromide (CTAB)-modified fly ash-based zeolite Na-A (CTAB@FZA) was prepared for the treatment of industrial wastewater contaminated with Cr(VI). CTAB@FZA evaluated using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (F...

Small angle neutron scattering (SANS) data are reported from a system that models the contamination of a clay/organic matter soil from a fuel spillage. The soil was represented as an aqueous dispersion of the synthetic clay mineral Laponite coated with lysine, and the contaminant was a representative jet fuel, quadricyclane, mixed with the detergent cetyltrimethylammonium bromide (CTAB). The ad...

Dissolution behaviour of both 5, 5-diphenyl hydantoin sodium commonly known as dilantin sodium (DS) and its corresponding marketed capsule dilantin have been studied in aqueous as well as micellar media. Percentage dissolution of both DS and its marketed capsule are found to be low as expected in aqueous medium due to its very low solubility in water. However, their dissolution tendency is foun...
