In this survey adsorption of some heavy metals such as cobalt and lead on montmorillonite and montmorillonite/copper oxide nano-composite is reported. Adsorption percent and adsorption capacity were studied under different conditions such as pH concentration of metal ions amount of clay and interaction time. The results show that an increase in absorption percent and absorption capacity wit...

The conversion of waste to wealth has recently grossed high attention as it possesses the ability boost economy any nation; hence, this research. In study, characterization and investigation mechanical properties nano- flux (CaO) welding powder developed from bio-agrowaste (eggshell) was carried out. Mild, galvanized stainless steel plates rods were used parent metals for experiment. Results ob...

Abstract A better understanding of the bonding and aggregation processes occurring between carbon nanomaterials metal oxide particles in aqueous solutions is important development novel nanosolids for applications areas sensor development, highly conductive paint, nanotube alignment, polymer composites, Li-ion batteries, many other areas. The current investigation reviews these presents a detai...

Backgrounds & objectives: Contamination of the environment by heavy metals, pollute water and agricultural products. The aggregation of these metals will cause various diseases for human. Therefore, it is important to study how to make them safe. The purpose of this study is to evaluate the efficiency of starch-iron oxide nanocomposite in removing two heavy metals, nickel and cadmium, from wast...

Crushing and grinding of materials are the most common processes sample preparation for subsequent analysis industrial application. Recently, has become one popular methods producing nano-sized powders. This study investigates certain features grain transformation in process ores with finely dispersed valuable components order to liberate them, as well specifics metallurgical raw materials, met...

In this review, we examine the greenest nanoparticles of zero-valent metals, metal oxides and metal salts, with emphasis on recent developments routes. Products from nature or those derived from natural products, such as extracts of several plants or parts of plants, tea, coffee, banana, simple amino acids, as well as wine, table sugar and glucose, have been used as reductants and as capping ag...

Based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. In the present research, 2D molecular dynamics simulations have been used to investigate such behaviors. Performing the planar simulations can provide a ...
