Background : Effluents containing synthetic dyes are hazardous to ecological systems and public health. Methylene blue is an important chemical aromatic dye which commonly used in textile industries. Due to being aromatic, it is often toxic, carcinogenic and mutagenic. The goal of this study was to investigate the efficiency of ZnO nano particles photocatalytic process for decolorization of met...

Through dip coating method monodisperse nickel nanoparticles assisted carbon membrane was prepared on porous alumina disc support. The solution by blending of thermally stable polymer polyphenylene oxide (PPO) and labile polyvinylpyrrolidone (PVP) followed addition nanoparticles. Size nanoparticles, surface porosity, average pore size, element composition optical properties the were investigate...

This topic prepared a composite nano-silver–tin slurry. According to the boiling point of dispersant, 300 °C is determined as sintering temperature. As amount tin added increases, shear strength Ag–Sn slurry gradually increases. When 1/20, reaches maximum 50 MPa. The increase in due strengthening second phase. exceeds drops sharply, mainly overgrowth Ag3Sn, product reaction silver and tin. poro...

BACKGROUND Nowadays, extensive technological advancements have made it possible to use nanopaints which show exciting properties. In IR Iran excessive radon levels (up to 3700 Bq m-3) have been reported in homes located in radon prone areas. Over the past decades, concerns have been raised about the risk posed by residential radon exposure. OBJECTIVE This study aims at investigating the effec...

This study includes the effect of wafer resistivity and intensity light on topography porous silicon surfaces which produced by photo chemical etching method, results showed that changing led to change porosity, where it found layer be less high value resistivity. 
 Once all wafers have same resistivity's that’s porosity focused.
 The production Nano crystalline structures control the...

Porous hollow glass microspheres have many uses, including encapsulation of active materials. In this paper a fast and facile method for fabricating porous hollow glass-microspheres was demonstrated by etching them using dilute hydrofluoric acid. Then, a highly reactive amine was infiltrated into the etched glass microspheres. Scanning electron microscopy was conducted for the hollow glass micr...

The effects of lanthanum hexaboride (LaB6) nano-particles on the electrical, thermal, and mechanical properties copper-based nanocomposites (Cu-LaB6) produced using microwave sintering (MS) spark plasma (SPS) processes were investigated in this study. Nano LaB6 particles reduced electrical conductivity Cu matrix via MS SPS by 20% 13%, respectively. Cu-LaB6 had lower thermal than unreinforced Cu...

Abstract The adsorption of CO 2 on a nano-calcium oxide (nano-CaO) adsorbent was investigated under different conditions temperature and supply pressure, considering kinetic, isotherm, thermodynamic parameters. CaO is crystalline material with high surface area nanosized particles porosity, which showed rapid initial rates in the moderate range studied. well described by pseudo-second-order int...
