Title: Investigation of ball milling in the morphology of nanoparticle

Abstract:

In this study, we investigated synthesized graphene and their nanocomposite by using ball milling as mechanochemical methods under solvent-free and wet conditions. Mechanochemical reaction without using solvent or wet condition has advantages as the environmentally benign nature, often of these reactions were occurred without using any catalyst that followed by green chemistry methods. In this research, we also showed that the morphology and exfoliation of graphene and nanocomposite was influence the time and the medium of the ball milling. For obtained special morphology of the nanoparticle using ball milling in a short time that can provide especial morphology such as rode, flower and etc., when we increased the time of the ball milling the morphology of the nanoparticle had no specific morphology. In this paper, we synthesized the multi-layer graphene-MnO₂ at different times by ball milling and have studied their morphology. Besides the time, we investigated the medium that can influence the morphology of exfoliation of graphite

Biography:

Sara Mashkouri, PhD in organic chemistry, had 9 papers published in ISI journals with 256 citations and more than 15 paper presented and posters in conference’s forced to designs green and scalable methods that can be scalable in industrial. She’s now working as an adviser in Technology incubators, Iran university of science and technology, and research in biotechnology and Nanocarrier. PhD passed in Tabriz university under supervisor Dr.Arsalani. The PhD thesis title is“ Green synthesis of two-dimensional carbon compounds and Feasibility study application in electronic” she synthesized graphene at green condition using citric acid as green row material to active the surface of graphene by the mechanochemical method. Beside of synthesized graphene and exfoliated graphite applied varistor compound. These studies showed that exfoliated graphite effect on properties of varistor and modification of these compounds. She hoped to design more nanocomposite under the green and cheap method that can be applied in industrials.
