In this work, to investigate the effect of reduced Graphene Oxide nanoparticles on the strength of concrete and the corrosion resistance of rebar inside it, Graphene Oxide nanoparticles were added to the mortar with different weight percentages of cement. The strength of concrete was evaluated by measuring the compressive strength of 7 days and 28 days and comparing with the results of the control sample. To investigate the effect of reduced Graphene Oxide nanoparticles on the corrosion resistance of rebar inside it, polarization and EIS tests were performed in a 3.5% salt solution. The results showed that the addition of reduced Graphene Oxide nanoparticles increases the compressive strength and electrical impedance of the concrete. It was also found that there is an optimal value that the addition of Graphene Oxide nanoparticles more than that value causes a relative decrease in concrete strength and electrical impedance. Finally, by simulating the equivalent circuit, the reason for the decrease in impedance and as a result the corrosion resistance by adding more than the optimal value was investigated.

The material was characterized by Fourier transform infrared (FT-IR), powder Xray diffraction (PXRD), and inductively coupled plasma (ICP) techniques. Furthermore, the catalytic behavior of Zn-Cd-MOF toward the Knoevenagel condensation reaction was investigated and good catalytic capability was achieved Manuscript profile

In this work, Cu@KF/Clinoptilolite NPs was synthesized using Petasites hybridus rhizome water extract as a simple and efficient green procedure. The obtained catalysts were characterized by XRD, SEM, EDX and TEM analysis. The average particle size diameter of the Cu@KF/Clinoptilolite nanoparticles was approximately 30 nm. The adsorption properties of Cu@KF/Clinoptilolite NPs for the removal of cefixime and 4-NP (4-nitrophenol) from aqueous environment were investigated. Using Petasits hybridus leaves water extract, high performance Cu@KF/Clinoptilolite nanoparticles were created in this study. They were then used in numerous reactions to demonstrate the reusability of the nanocatalyst and serve as an environmentally friendly adsorbent for the removal of cefixime (CFX). Also, the catalytic activity of the green synthesized Cu/KF/CP NPs was evaluated in the reduction of organicpollutants such as 4-NP in water at mild conditions. The results indicated that the biosynthesized NCs have very high and effective catalytic activity for organic pollutants within a short time. Some benefits of this process are the quick reaction time, high product yields, and simplicity of catalyst and product separation. Manuscript profile

Ion distribution on the spinel structure of ferrite nanoparticles is one of the critical factors that can affect magnetic properties. Therefore, if a method changes ion distribution, it can be used for fabrication (synthesis) of nanoparticles with different magnetic properties that apply in the diverse of technology field. In this work, the dependence of magnetic characteristics of the cobalt-doped nickel ferrite nanoparticles on Polyvinyl alcohol (PVA) assisted co-precipitation processes was studied. The structural and magnetic measurements were made employing XRD and VSM. Nanoparticles with a cubic spinel structure and an average size of about 29 nm have been synthesized, and their structure was confirmed using the XRD pattern and Sherrer’s equation. According to the obtained hysteresis loops of the five sets of synthesized nanoparticles, the coercive field and magnetization are different because of the interaction between polymer and metal ions in the reaction medium that causes a kind of ion immobilization and different ion distribution over the spinel structure. Such polymer-based synthesis procedures can be used to fabricate of magnetic nanoparticles with tunable magnetic properties. Manuscript profile

In this study, the biosynthesis of silver nanoparticles was done using Bacillus subtilis bacterium cultured in corn steep liquor (CSL) nutrient. The biosynthesized nanoparticles were characterized by several techniques including FT-IR, XRD, UV-Vis, SEM, EDX, and TEM. The absorption spectrum of the nanoparticles indicated the maximum absorption at 436 nm. The SEM image confirmed the nanoparticles had polydisperse spherical morphology (~20nm). Also, the TEM image showed the nanoparticles had spherical or elliptical shape and the approximate diameter of the particles was between 10-20 nm. Morphological studies showed that the nanoparticles were completely separated and no aggregation was observed. Moreover, XRD studies confirmed that the produced nanoparticles were crystallized in the FCC crystal lattice. The antibacterial activity results indicated that the synthesized nanoparticles had significant effect against Escherichia coli bacteria, and the inhibition zone was equal to Gentamicin. So, the production of silver nanoparticles using green method is economically very economical, and can be a method for the production of silver nanoparticles in industrial scale. Manuscript profile

In this research, four improved and scalable methods for the synthesis of lauryl amine have been described. In this research, attempt has been by investigated the synthesis methods of lauryl amine, made to provide an easy and cost-effective method for the synthesis of lauryl amine as a surfactant and anti-cake with a wide range of applications. lauryl amine was synthesized from the primary materials of lauric acid, lauramide and lauronitrile in the presence of various catalysts and reducing agents. The advantages and disadvantages of each of these methods were investigated and compared to industrial methods. In the reduction of luramide and Lauronitrile to lauryl amine, diborane reductant was used as a new method for the first time. In this article, with an efficient and new method, lauryl amine was synthesized in the presence of ammonia and aluminum oxide with a overall yield of 63% from lauric acid. In this method, lauric acid is converted to Lauramide and finally reduced to lauryl amine. Manuscript profile
