In this article, nanocomposites based on Chitosan (CS)/ poly vinyl alcohol (PVA) and graphene oxide (GO) nanoparticles were prepared by casting the stable aqueous mixture of the components in a mold. The prepared nanocomposites were characterized using Fourier-transform infrared spectroscopy...

Biomass is a key source of energy to power the world's growing hunger for energy, whilst replacing fossil fuels as the fight against greenhouse gas emissions intensifies. This has led to a significant focus on not only using biomass as a source of energy, but also on the need to use it...

Ionocovalency theory is defined “…everything exists in ionocovalency, the harmony of ionic energy with the covalent environment.” The authors have succeeded in thoroughly studying ionic energy part of the ionocovalent theory, and will now focus target on the covalent environment part of...

Conventional decontamination methods utilize water-based systems, which generate high amounts of secondary wastes. Herein, the authors describe an environmentally benign decontamination method using liquid and supercritical CO2. The use of CO2 as a solvent affords effective waste reduction by...

This article describes the addition of multi-walled carbon nanotubes (MWCNT) into the epoxy as well as dispersing media during fabrication were used as factors to investigate the viscoelastic properties of epoxy/MWCNT nanocomposite. The quality of the dispersion was evaluated through studying...

In this article, modified neural networks using genetic algorithms were employed to investigate the simultaneous effects of four of the most important parameters, namely; solution concentration (C); spinning distance (d); applied voltage (V); and volume flow rate (Q) on mean fiber diameter...

The purpose of this article is evaluating the effect of renewable energy on economy growth. Therefore, the production function has been examined in OPEC members in 2012-2016 using the dynamic board data based on energy consumption. The results reveal that among variables, the existence of...

This article examines the systematized and defined laws of anomalies in the filling of the electronic orbitals of the periodic table of chemical elements. The particulars of the chemical compounds caused by these anomalies investigated. It is shown that the deviation from the accepted order of...

This article focuses on the electrospinning of nanofibers from rice straw as a renewable, cheap natural resource. To facilitate the formation of cellulose nanofiber, PVA was utilized as a secondary plasticizing polymer. The polymer solution contained 75% w/w cellulose and 25% w/w PVA using...

In the present article, the authors have prepared nanocomposites based on chitosan (CS) and double walled carbon nanotubes (functionalized with carboxyl groups (DWCNT-COOH) and un treated DWCNT) by casting the stable mixture in a mold. Different concentrations of DWCNT were used in the...
