An Investigation of Microstructures in Cationic/Anionic Surfactant Suspensions by Cryogenic Transmission Electron Microscopy
Abstract Cryogenic transmission electron microscopy (cryo-TEM) has been used to image a variety of single and mixed cationic–anionic surfactant suspensions in water and in the presence of salt. AExpand
Synthesis and Characterization of Magnetic Nanoparticles in Spontaneously Generated Vesicles
Unilamellar vesicles, formed spontaneously by mixing single-tailed anionic and cationic surfactants (dodecylbenzenesulfonic acid (HDBS) and cetyltrimethylammonium bromide (CTAB), respectively), haveExpand
Synthesis and characterization of magnetic iron oxide nanoparticles via w/o microemulsion and Massart's procedure
Abstract Water in oil microemulsion system was used to prepare magnetic iron oxide nanoparticles. Two different volumetric ratios of Fe2+ and OH− (1:1 and 2:1) were investigated. The as-synthesizedExpand
Magnetic Nanoparticles Produced in Spontaneous Cationic-Anionic Vesicles: Room Temperature Synthesis and Characterization
Abstract Unilamellar vesicles formed spontaneously by forming solutions of single-tailed cationic and anionic surfactants [cetyltrimethylammonium bromide (CTAB) and dodecylbenzenesulfonic acidExpand
Synthesis of PdO/CeO2 mixed oxides catalyst for automotive exhaust emissions control
Abstract PdO/CeO2 mixed oxide catalysts were synthesized using a modified deposition-precipitation technique. The catalyst was quite effective in oxidizing hydrocarbons (HC) and carbon monoxide (CO),Expand
Polymer matrix templated synthesis: Cobalt ferrite nanoparticles preparation
Cobalt ferrite (CoFe 2 O 4 ) nanoparticles were successfully synthesized by polymer matrix templated synthesis. Synthetic ion-exchange resins were used as hosts for the coprecipitation of cobaltExpand
Preparation of iron–platinum nanoparticles in water/triton/cyclohexane microemulsions
Abstract Iron–platinum (FePt) nanoparticles at two different molar ratios of Fe 2+ to Pt 4+ of 1:1 and 3:1 have been prepared by coreduction of H 2 PtCl 6 and FeCl 2 with hydrazine in water/tritonExpand
Synthesis and Characterization of Nickel-Iron-Silicon Nitride Nanocomposite
Nickel-iron-silicon nitride nanocomposite thin films were prepared by electrodeposition technique. The deposition was performed at current density of 11.5 A dm-2. Nano-size silicon nitride was mixedExpand
Effect of Nitric Acid Concentrations on Synthesis and Stability of Maghemite Nanoparticles Suspension
The increasing concentration of nitric acid in synthesis of maghemite nanoparticles produced smaller size particles, lower magnetization, better thermal stability, and more stable maghemITE nanoparticles suspension. Expand
Melting of multipass surface tracks in steel incorporating titanium carbide powders
Abstract Overlapping tracks were processed by melting preplaced titanium carbide (TiC) powder on steel surfaces using a tungsten inert gas torch. The tracks produced ∼1·0 mm melt depth free fromExpand
