In this article, we consider an asynchronous discrete-time opinion dynamics model for a social influence network, which consists of population interacting individuals, each holding private and expressed opinions. At time instant, single individual activates updates both his or her opinions simultaneously. While individual's new is shaped by opinion, the neighbors, attachment to existing prejudice, instead tradeoff between true "public opinion," representing current norm standard from...
In this report, we described the very fast synthesis of gold nanoprisms under microwave heating for 60-90 s in presence 2-naphthol (2-N) as a new reducing agent. The growth particles with different shapes (spherical, polygonal or triangular/prisms etc.) were found to be functions surfactant-to-metal-ion molar ratio and concentration 2-N. evolved approximately 110 +/- 10 nm diameter size shape was successfully tuned just by varying reactants. This process can extended other nonmaterial...
ZnO nanorod arrays were synthesized by hydrothermal method under different growth times. The effect of time on nanorods morphology was investigated systematically. Results illustrate that with hexagonal wurtzite structure grow vertically the Si substrates. length increases increasing time. In our experiments, quenching stage plays a key role in forming tips nanorods. With no more than 1h, solution is continuous heating state and doesn’t reach set temperature 180oC. Therefore, longer means...
A new phosphine-free approach has been developed to synthesize high-quality cadmium selenide (CdSe) nanocrystals with cubic zinc-blende structure, by using the highly reactive selenium (Se) precursor at milder temperature than that used in traditional phosphine route. This Se was obtained from reduction of powder sodium borohydride N,N-dimetbylformamide, absence phosphine. Without addition other long-chain coordinating substances this approach, alkylamines such as dodecylamine (DDA) and...
A photodeposition methodology is investigated to synthesize novel ZnO nanoporous layer with high yield and uniformity on TiO<sub>2</sub> nanotubes.
The ZnO nanorods with sharp tip have been fabricated via water cooling treatment during the hydrothermal growth. morphology and crystal structure of zinc oxide nanostructure were examined by field-emission scanning electron microscopy x-ray diffraction, respectively. structural characterizations revealed that as-synthesized single crystalline, a hexagonal phase. It has demonstrated rate is critical factor synthesis comparing different conditions. growth mechanism for proposed on basis...
