CTAB Mediated Reshaping of Metallodielectric Nanoparticles
Nano Letters, 2003We report on the dramatic chemical reshaping of metallodielectric nanoparticles upon exposure to cetyltrimethylammonium bromide (CTAB) in aqueous solutions. Metal nanoshells possessing a silica core with a gold shell were observed to undergo a morphological change from their initial shell structure to that of large, elongated gold nanoparticles or ...

Highly ordered CTAB-templated organosilicate films
Journal of Materials Chemistry, 2005Well- ordered organic - inorganic mesoporous films are prepared using an original two- step synthesis and compositions up to 50 mol% methyltriethoxysilane ( MTES). These materials exhibit the three different mesostructures ( 2D- hexagonal, 3D- hexagonal and cubic) previously observed in the pure silica system with significant modifications of their ...

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1997
Abstract ESR spectroscopy was used in this study to monitor the aggregation behavior of cationic surfactant [cetyltrimethylammonium bromide (CTAB) in aqueous solution by measuring the rotational correlation time τ of a nitroxide labeled fatty acid probe (5-doxyl stearic acid) as a function of the surfactant concentration.

Fast local dynamics in CTAB micelles
AIP Conference Proceedings, 2012Molecular dynamics of cetyltrimethylammonium Bromide (CTAB) micelle has been studied in the temperature range 310-340 K using quasielastic neutron scattering technique. Data analysis clearly shows the presence of two distinct motions; i) whole micellar motion or global diffusion and ii) faster internal motion of the CTAB monomer.

Abstract Mesoporous γ-aluminas are prepared via a facile one-pot hydrothermal method using aluminum sulfate as a precursor, urea as precipitating agents, sodium tartrate and CTAB (cetyltrimethylammonium bromide) as co-templates respectively. Characterizations of the intermediate aluminum oxyhydroxides by IR, XRD, element analysis and TG show that the

Acid–base equilibrium of puerarin in CTAB micelles
Journal of Pharmaceutical and Biomedical Analysis, 2007Electronic absorption spectra, fluorescence emission spectra, 1HNMR and ab initio quantum calculation are used to study the acid-base equilibrium of puerarin in cetytrimethylammonium bromide (CTAB) micelles with different microstructures and microenvironments.
