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 ...

Exposure to anionic (sodium dodecyl sulfate, SDS), cationic (cetyl trimethyl ammonium bromide CTAB) and non ionic (Triton X-100) surfactants at a sub lethal concentration of 1 ppm resulted in severe oxidative stress in the hepatic, renal and cardiac tissues of fresh water adapted Oreochromis mossambicus. Hepatic catalase showed significant increase (P<0.001) in all the surfactant exposed fish, ...

Kinetic studies on the reduction of dithizone by stannous chloride was carried out in acidic medium (HCl) at room temperature. The study was made in the presence of cationic surfactant, Cetyl Trimethyl ammonium Bromide (CTAB) and anionic surfactant, Sodium Dodecyl Sulphate (SDS). The reduction of dithizone in the presence of CTAB is much faster than in the absence of surfactant in acidic medium...

A program based on MCR-ALS applied...

One third of all genes of various organisms encode membrane proteins, emphasizing their crucial cellular role. However, due to their high hydrophobicity, membrane proteins demonstrate low solubility and a high tendency for aggregation. Indeed, conventional two-dimensional gel electrophoresis (2-DE), a powerful electrophoretic method for the separation of complex protein samples that applies iso...

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...

In this work, we studied nonlinear dynamics and optical limiting (OL) effects of pulse trains in zinc porphyrins meso-tetrakis methylpyridiniumyl (Zn2+TMPyP) sulfonatophenyl (Zn2+TPPS) porphyrin J-aggregates. The environments were selected as aqueous solutions micelles sodium dodecyl sulfate (SDS) cetyltrimethyl ammonium bromide (CTAB). Our numerical results show that both Zn2+TMPyP Zn2+TPPS ar...

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....
