The turbidimetric methods here described are based on the formation of relatively insoluble complexes between isolated acid mucopolysaccharides and cetyltrimethylammonium bromide.’ Some of the properties of these complexes have recently been described by Scott (1). We found that the amount of turbidity developed when the cetyltrimethylammonium bromide is added to a solution of acid mucopolysacc...

A facile and efficient approach for the fabrication of mesoporous spherical aggregates of anatase nanocrystals is reported in this paper. Cetyltrimethylammonium bromide was used as the structure-directing agent, and the interaction between cyclohexane microdroplets and the cetyltrimethylammonium bromide self-assemblies led to the assembly of 4-5-nm-sized anatase nanocrystals into spherical aggr...

Gold nanorods stabilized by binary ligand mixtures of cetyltrimethylammonium bromide (CTAB, primary ligand) and ascorbic acid or hydroquinone were investigated complementary synchrotron radiation-induced spectroscopies microscopies, with the aim...

ABSTRACT. In the present work, mathematical models relating mass density and specific volume of solution with concentration for aqueous solutions anionic (sodium lauryl sulfate - SLS) cationic (cetyltrimethylammonium bromide CTAB) surfactants (0-10% (w/w)) have been investigated. The experimental studies were performed to study effect on solution. Mass increases, decreases an increase in both s...

Mesoporous silica nanomaterials with varied morphologies and pore structures, including nanospheres, nanoellipsoids, helical nanorods and multi-lamellar nanovesicles, were synthesized by using cetyltrimethylammonium bromide (CTAB) and sodium bis(2-ethylhexyl) sulfosuccinate (AOT) as co-templates.

DNA microspheres formed by self-assembly of DNA three-way junctions with self-complementary sticky-ends undergo an unexpected dynamic transformation from filled spheres into hollow capsules upon addition of cationic surfactants such as cetyltrimethylammonium bromide.

Mesoporous silica nanomaterials of different shapes (film, platelet, sphere, rod) were synthesized simply by tuning the mole ratio of dual cationic surfactant templates, cetyltrimethylammonium bromide (CTAB) and tetrabutylammonium iodine (TBAI). The film showed the most potent antibacterial activity against mycobacteria.
