Monodisperse sub-10 nm Rh nanocubes were synthesized with high selectivity (>85%) by a seedless polyol method. The {100} faces of the Rh NCs were effectively stabilized by chemically adsorbed Br- ions from trimethyl(tetradecyl)ammonium bromide (TTAB). This simple one-step polyol route can be readily applied to the preparation of Pt and Pd nanocubes. Moreover, the organic molecules of PVP and TT...

The correlation between the growth behaviour and geometrical shape for CTAB-rich mixed micelles formed by the cationic surfactant hexadecyl trimethyl ammonium bromide (CTAB) and the anionic surfactant sodium octyl sulphate (SOS) has been investigated with small-angle neutron scattering (SANS). Small tablet-shaped micelles formed by CTAB are found to grow only weakly in size with increasing surf...

Dynamin is a GTPase enzyme involved in membrane constriction and fission during endocytosis. Phospholipid binding via its pleckstrin homology domain maximally stimulates dynamin activity. We developed a series of surface-active small-molecule inhibitors, such as myristyl trimethyl ammonium bromide (MiTMAB) and octadecyltrimethyl ammonium bromide (OcTMAB), and we now show MiTMAB targets the dyna...

In 1916 Jacobs, Heidelberger, and coworkers at the Rockefeller Institute reported the discovery of a new class of synthetic compounds which possessed potent bactelicidal properties. By reacting hexamethylenetetramine with a large variety of substituted benzylor alkyl-halides, nujmerous quaternary salts of this base were obtained. It was observed that most of these salts had pronounced bacterici...

A Gemini surfactants (GS) which are bis quaternary ammonium salt. It is prepared from tetramethyl ethylene diamine (TMEDA) with cetyl bromide, while an ordinary surfactant (OS),which salt, trimethyl amine (TMA) and bromide. They were identified by elemental analysis IR spectroscopy.
 Comparing the GS,OS commercial surfactants, shows interesting properties have a variety of uses, such as De...

A new nanocomposite based on conducting polyaniline (PANI) and Algerian montmorillonite clay dubbed Maghnite is proposed to combine thermal properties (Mag). The PANI-Mag nanocompo-sites samples were made by in situ polymerization with CTABr (cetyl trimethyl ammonium bromide) as the galleries' organomodifier. In terms of ratio, electrical obtained nanocomposites are investigated. As amount incr...
