Boletín número 51 - Marzo 2019


pp. 1

Dr. Behzad Aghabarari

The carbon-based materials have been interested by researchers during the last decades because the carbon sources are abundantly available in the world wide...

Investigating the Accelerated Electrochemical Corrosion Protection Performance of Coal-Tar and Bitumen Enamel Coating for Pipelines

pp. 2-4

B. Aghabarari, S. Pourhashem, B. Moeinifard

This work attempts to give a general zoom to the nanostructured carbon materials from their appearance, discovery and fabrication, until their applications and impacts in the scientific field. The three main carbon nano-allotropes: fullerenes, carbon nanotubes and graphene, are revised in order to stablish a general overview. Finally, some alternatives on the potential growing of these materials are also presented...

A short review on various applications of carbon nanotubes and graphene nanosheets in different industries

pp. 5-12

B. Aghabarari, S. Pourhashem, M.R. Vaezi

Carbon based nanomaterials including carbon nanotubes and graphene nanosheets have attracted the attention of researchers due to their outstanding extraordinary properties. In this article, we have presented the researches on the application of carbon nanotubes and graphene sheets in Nanotechnology and Advanced Materials at Materials and Energy Research Center...

Evaluation and optimization of supercritical extraction of insulin from Otostegia persica

pp. 13-19

N. Nourinasab, S.M. Ghoreishi, S.S. Banifatemi

In this study, the extraction of insulin from otostegia persica was enquire by Soxhlet extraction and modified supercritical CO2 with methanol as solvent and 30 min of static time. Design of experiment was executed with response surface methodology (RSM) using Mini Tab software 17....

Effects of chemical and mechanical funtionalization of carbon nanotubes on the behavior of a CNT/Phenolic nanocomposite

pp. 20-25

M.J. Hadianfard, M. Alizadeh and M. Moradzaman

Carbon nanotubes and their treatments play an important role in fabrication and properties of the nanocomposites. In this study effects of acid functionalization and mechanical treatment of CNTs by ball milling on the chemical structure, weight loss and mechanical strength of a 1 weight % CNTs reinforced phenolic polymer has been investigated by using FTIR, XRD, TGA, electron microscopy and tensile tests...

The Wear Behavior of Au-Co/Diamond-Like Carbon Composite Electrochemical Coating

pp. 26-31

S.M.M. Hadavi, P. Gegan

Gold—cobalt/nanodiamond composite coatings were deposited on a commercially pure copper substrate by electrodeposition method. Gold and cobalt salts of KAu(CN)2) and CoSO4 were used as the coating electrolyte to have about 8 μm thick Au-0.6wt% Co coating layer. Nanodiamond particles of 5 nm in size were used in the electrolytes carrying 0, 5 and 12 g/l of these particles. By passing direct current for about 10 minutes, a composite coating including nanodiamond particles in the gold-cobalt matrix was formed...
