The action of some detergents on the incorporation of glucose from uridine diphosphate glucose or adenosine diphosphate glucose into the potato tuber starch grain was studied. It was found that the cationic detergent, cetyltrimethylammonium bromide, produces a rapid binding of both sugar nucleotides to the grain and a great increase in the incorporation of glucose into the polysaccharide. Kinet...

An acetylene black electrode modified by an adsorbed cationic surfactant, cetyltrimethylammonium bromide (CTAB), was developed. The influences of various types of surfactants on the electroreduction of O2 were investigated. It was demonstrated that a cationic surfactant, CTAB, on the surface of the electrode could significantly decrease the overpotential of dioxygen reduction, and the reduction...

Abstract The process of lubricant penetration into frictional interfaces has not been fully established, hence compromising their tribological performance. In this study, the characteristics deionized water (DI water) containing an electroosmotic suppressant (cetyltrimethylammonium bromide (CTAB)) and promoter (sodium lauriminodipropionate (SLI)), were investigated using steel-on-steel friction...

Biomimetic morphogenesis of sophisticated mesostructured silica micropottery with a novel 3D hierarchically ordered structure and diverse morphologies was realized by hydrolyzing tetraethylsiloxane (TEOS) in concentrated HNO3 solutions containing cetyltrimethylammonium bromide (CTAB). It was proposed that the unique micropottery was self-organized by helical coiling of hexagonally ordered mesos...

Recently we reported that removal of noncovalently bonded protein from glutenin resulted in decreased viscoelasticity. In that study, two glutenin fractions were isolated by successive gel filtration of glutenin on Sephadex G-200 in the solvents acetic acid-guanidine hydrochloride (GuHCl)-cetyltrimethylammonium bromide (AGC) and sodium dodecyl sulfate (SDS). This note reports the S20,W values o...

Here we describe the synthesis of Au nanorods directly on glass surfaces using seed-mediated deposition of Au from AuCl4- onto surface-attached 3-5 nm diameter Au nanoparticles (AuNPs) in the presence of cetyltrimethylammonium bromide (CTAB). The average length (200 nm to 1.2 microm) and aspect ratio (6-22) of the nanorods increases with increasing AuCl4- concentration. Short, low aspect ratio ...

The oxidation of ethylene glycol by periodate (IO4 (-)) was studied in different micellar aggregates of cetyltrimethylammonium bromide (CTABr) and dodecylamine (DA) by means of UV/Vis spectroscopy. The observed constant K o was obtained by monitoring the disappearing of ethylene glycol with time at a suitable wavelength under pseudofirst condition. Addition of CTABr and DA inhibits the reaction...
