Chennai researchers’ simple approach to produce graphene nanosheets

Excelente contribución para el repertorio de técnicas en la obtención de Grafeno, un maravilloso material bidimensional con espesor atómico que muestra su potencial para revolucionar el mundo.

En Venezuela poco a poco se comienzan a sumar mas científicos en la investigación de este sorprendente material. En la facultad de ciencias de la Universidad Central de Venezuela (UCV-Ciencias) varios estudiantes de la licenciatura en física  enfocan actualmente sus proyectos de tesis en el Grafeno, algunos desde el enfoque teórico modelando el comportamiento cuántico del material y otros en el área experimental estudian sus métodos de obtención y se plantean posibles aplicaciones.

Actualmente me encuentro en el proceso de desarrollo de mi proyecto de tesis en el área experimental para la obtención y caracterización de este material,  junto con mi tutor hemos encontrado que el método que plantean  M. Balasubramaniam y S. Balakumar (Universidad de Madras) es uno de los mas simples de llevar a cabo por lo que lo tomare de base para implementar la obtención de Grafeno en mi proyecto.

Quiero compartir con mucho respeto la traducción que realice del articulo que ellos han publicado sobre:

Método de exfoliación de nanocapas de Grafeno por medio de Tri-Solvente asistido con Ultrasonicación para aplicaciones en Supercapacitores.

Excellent contribution to the repertoire of techniques in the production of graphene, a wonderful two-dimensional material with atomic thickness that shows its potential to revolutionize the world.

In Venezuela little by little they are beginning to add more scientists in the investigation of this surprising material. In the faculty of science of the Central University of Venezuela (UCV-Sciences) several students of the degree in physics are currently focusing their thesis projects in the graphene, some from the theoretical approach modeling the quantum behavior of the material and others in the experimental area Study their methods of production and possible applications.

Currently I am in the process of developing my thesis project in the experimental area for the obtaining and characterization of this material, together with my tutor we have found that the method proposed by M. Balasubramaniam and S. Balakumar (University of Madras) is One of the simplest to carry out so I will take the base to implement the obtaining of graphene in my project.

I want to share with great respect the translation you make of the article that they have published about :

Tri-Solvent Mediated Probing of Ultrasonic Energy towards Exfoliation of Graphene Nanosheets for Supercapacitor application (Spanish)

Science Chronicle

nanosheets Dr. Balakumar (left) and Balasubramaniam of the University of Madras used ultrasound and a mild solvent to produce graphene nanosheets.

By using a simple, inexpensive, quick process researchers from the University of Madras have been able to produce a monolayer or a few layers thick graphene nanosheets from graphite material without using any strong oxidising or reducing agents. The results were published in the journal Materials Letters.

Among several techniques adopted to synthesize graphene from graphite, the liquid phase exfoliation methods have been found to be facile and cost-effective. Yet, the use of strong solvents and relatively low yield have turned out to be major drawbacks limiting its utilisation in the large-scale production of graphene.

“Commercialization of high quality graphene sheets calls for the exploration of a simple, effective, and inexpensive method for its engineering and environmental applications,” says Dr. S. Balakumar, Director of the National Centre for Nanosciences and…
