Carbon materials of either the nano-sizes or nano-structures are referred to nanocarbons, which from buckminsterfullerene (C60) discovered in 1985 to recent graphenes have attracted great attention of scientists and engineers in the wide fields of science and technology. Here we briefly describe nanocarbons such as graphene and carbon nanotubes (CNTs) including carbon nanofibers (CNFs) and carbon nanohorns (CNHs Read More

A comprehensive analysis of the growth of research activity has been conducted in the field of “Renewable Energy” originating from Arab countries. A bibliometric analysis based on databases Scopus was carried out to follow research activities in this field during the period from 1966-2014. Both quantitative and qualitative perceptions were taken into consideration. This study will improve the understanding of research Read More

Successfully studies were developed to produce reduced graphene oxide by green reduction of graphene oxide using environmentally-friendly reducing agents. Here for the first time, we report the green reduction of oxidized graphite (OG) to reduced graphene oxide (RGO) using the green plant called Zygophyllum album L.f. (Z. album) which revealed strong reducing activity. Techniques of TEM, Raman, FTIR and BET were c Read More

Esterified modified corn starch has been prepared with corn starch as raw material, acetic acid as activator, acetic anhydride as esterifying agent, and concentrated sulfuric acid as catalyst. Certain substitution degree (DS=0~0.5) of starch acetate (SA) was prepared. Esterified starches reaction conditions were optimized by single factor and orthogonal experiment. Esterified starch was characterized using Fourier transforms infr Read More

New reaction scheme is suggested for the initiated nonbranched-chain addition of free radicals to the multiple bond of the molecular oxygen. The scheme includes the addition reaction of the peroxyl free radical to the oxygen molecule to form the tetraoxyl free radical. This reaction competes with chain propagation reactions through a reactive free radical. The chain evolution stage in this scheme involves a few of free radicals Read More
