The synthesis of highly crystalline mesoporous materials is key to realizing high-performance chemical and biological sensors optoelectronics. However, minimizing surface oxidation enhancing the domain size without affecting porous nanoarchitecture are daunting challenges. Herein, we report a hybrid technique that combines bottom-up electrochemical growth with top-down plasma treatment produce ...

Abstract In this work, the compressive properties of sintered nano-silver applied to third generation semiconductor at room temperature are tested a loading rate 10 -2 s -1 . The stress-strain curve shows obvious elastic and plastic stage, with failure pore wall sintering neck, damage accumulates gradually until failure. microstructure is analyzed statistically by scanning electron microscope. ...

Coupling between nanoplasmonics and semiconducting materials can enhance complement the efficiency of almost all semiconductor technologies. It has been demonstrated that such composites light coupling to nanowires, increase photocurrent in detectors, enable sub-gap detection, allow DNA produce large non-linearity. Nevertheless, tailored fabrication using conventional methods remains a formidab...

The use of colored semiconductor oxide like copper (II) oxide and nickel (II) oxide for photocatalytic bleaching of rose bengal was investigated in detail. In order to harness the solar energy, the effective wavelength of the photocatalyst is to be expanded into the visible region and that increases the rate of photocatalytic bleaching of the dye. Progress of the reaction was observed spect...

The photodegradation of Ponceau-S dye was investigated using UV radiation in presence of nanosized Fe2 O3 .Removal efficiency of Ponceau-S was sensitive to the operational parameters such as dye concentration, catalyst dose, pH, contact time, TOC and COD. The photocatalytic treatment of red colored Ponceau-S dye by magnetic nano semiconductor (Fe2 O3 )is an effective, economic and faster mode. ...

Abstract Long-term stability and selectivity are crucial for the practical application of gas sensors, which closely related to microstructure composition sensor materials. In this work, Co-based metal organic framework (MOF) is used as a precursor prepared by simple hydrothermal method. After calcination, series Co3O4 nanospheres with various microstructures derived. When calcination temperatu...

Carbon nanotubes have generated much research interest and potential applications due to their unique properties such as their high tensile strength, high thermal conductivity, and unique semiconductor properties. Vertically-aligned carbon nanotubes (VA-CNTs) have been used in applications for electrochemical systems in energy storage systems and desalination systems. Typical methods of charact...

importance of covalent bonded two-dimensional monolayer nanostructures and also hydrocarbons is undeniably responsible for creation of new fascinating materials like polyphenylene polymer, a hydrocarbon super honeycomb network, so-called porous graphene. the mechanical properties of porous graphene such as its young’s modulus, poisson’s ratio and the bulk modulus as the determinative properties...

abstract: this work presents a numerical study to investigate the heat transfer characteristics of a 2-d rectangular composite porous radiant burner (cprb). in the construction of porous burner, the porous layer is considered to be composite consisting of upstream and downstream layers with equal thickness but with different physical and radiative properties. in the present work, a two dimensio...
