Zinc oxide (ZnO) possesses superior chemical and physical properties so that it can occupy an essential position in the application of nanostructures. In this paper, ZnO nano-rod arrays were synthesized by a simple one-step hydrothermal approach with assistance cetyl trimethyl ammonium bromide (CTAB). Exposure {0001} facets could be controlled adjusting amount CTAB maximum exposure nanorods is ...

The utilization of nanoparticle in ethanol-diesel emulsions combustion catalyst is important. For this study, ethanol and diesel fuels are emulsified varying the amount as 5, 10, 15% volume ratio designated E5, E10, E15, respectively, by using span 80 tween emulsifying agents. Nickel Zinc Iron Oxide (NiZnFe2O4) used each fuel sample with a dose rate 25, 50, 100 ppm. Cetyl Trimethyl Ammonium Bro...

In this study, the effects of hydrochloric acid (HCl) and acetic (HAc) modification on hexadecyl trimethyl ammonium bromide (HTAB) K+ adsorption characteristics a natural zeolite were investigated. Electrokinetic evaluations showed that HCl had more prominent effect zeta potential compared to HAc. Additionally, pH regulation behavior acid-modified samples was found differ from sample it in agre...

Morphological modification of bulk layered double hydroxides (LDHs) into surface-engineered, porous materials enabled effective, base-catalyzed liquid phase Knoevenagel condensation in water. The increase the number accessible basic sites on LDH engineering led to enhancement reaction rate, whereas significant changes relative strength were found cause remarkable differences chemoselectivities....

The thermodynamic parameters of interaction between calf thymus histone H A and dodecyl trimethyl ammonium bromide (DTAB), a cationic surfactant, in aqueous solutions of pH 3.2, 6.4 and 10.0 were measured over a wide range of DTAB concentrations by equilibrium dialysis at 27°C and 37°C and are discussed. The data are used to determine the free energy from the Wyman binding potential theore...

in the present  paper electrical conductivity (ec) of colloidal gas aphron (cga) suspensions was measured for anionic and cationic surfactants (sodium dodecyl sulfate (sds) and tetradecyl trimethyl ammonium bromide (ttab)). experiments were made for different concentrations of sds (6, 8.1, 10 mm) and ttab (2, 3.51, 5 mm). cga drainage behavior was observed and measured using 1 liter measuring c...

TiO2-SiO2 composites were synthesized using cetyl trimethyl ammonium bromide (CTAB) as the structure directing template. Self-assembly hexadecyltrimethyl- ammonium bromide TiO2-SiO2/(CTAB) were soaked into silver nitrate (AgNO3) aqueous solution. The Ag-TiO2-SiO2(Ag-TS) composite were prepared via a precipitation of AgBr in soaking process and its decomposition at calcination stage. Structural ...

Dryobalanops belong to a member of Dipterocarpaceae, which has high economic value. Due illegal harvesting for its wood, the population tends decrease every year, so rapid conservation effort was needed. D. oblongifolia and lanceolata were important members dryobalanops, have listed as endangered (EN), according IUCN. This study aims provide information on DNA isolation amplification process. d...

In the present  paper Electrical Conductivity (EC) of Colloidal Gas Aphron (CGA) suspensions was measured for anionic and cationic surfactants (Sodium Dodecyl Sulfate (SDS) and Tetradecyl Trimethyl Ammonium Bromide (TTAB)). Experiments were made for different concentrations of SDS (6, 8.1, 10 mM) and TTAB (2, 3.51, 5 mM). CGA drainage behavior was observed and measured using 1 liter measuri...

Our study includes removal of Cr(VI) by using mixed surfactants (Non-ionic: Cationic). A common cationic surfactant Cetyl trimethyl ammonium bromide(CTAB) with two different nonionic surfactant Triton X-100 and Tween-80 were used to remove Cr(VI) by micellar enhanced ultrafiltration technique.The effect of parameters such as initial feed metal ion concentration, pH and filtration time on % Reje...
