Abstract: Graphene is a one atom thick layer of carbon atoms. Its extraordinary behavior is owed to the atomic arrangement and 2D nature. Single layer graphene is impermeable to all gases and liquids but graphene oxide exhibits highly selective permeability to water molecules and has thus shown potential for filtration applications. Graphene oxide can be prepared from graphite by introducing oxygenated functionalities using oxidizing agents. These functionalities expand the layer separation between two stacked layers and make the material hydrophilic. I will discuss our recent developments on application of graphene based membranes for water purification and water absorption. We have achieved extremely high water flux for graphene based membranes in practical conditions. Our graphene oxide membranes show outstanding water adsorption properties and it outperforms silica gel a commercial benchmark for desiccation. I will present water filtration and water adsorption characteristics of graphene oxide membranes. In addition, I will present our findings on CVD graphene and introduce our recently developed Green-CVD method.

 

Bio: Rakesh Joshi is a Lecturer at the School of Material Science and Engineering of UNSW Sydney.

Joshi is also the Research Director of the Global Graphene Application Pty Ltd.  Joshi is a Fellow of the Royal Society of Chemistry (FRSC).  He is among a select group of researchers who have been awarded each of the world’s most prestigious relevant International Research Fellowships; the (1) Japan Society for Promotion of Science (JSPS) Invitation Fellowship; the (2) Alexander von Humboldt Experience Researcher Fellowship and the (3) Marie Curie International Fellowship (European Union).

 

A warm welcome to the modified and updated website of the Centre for East Asian Studies. The East Asian region has been at the forefront of several path-breaking changes since 1970s beginning with the redefining the development architecture with its State-led development model besides emerging as a major region in the global politics and a key hub of the sophisticated technologies. The Centre is one of the thirteen Centres of the School of International Studies, Jawaharlal Nehru University, New Delhi that provides a holistic understanding of the region.

Initially, established as a Centre for Chinese and Japanese Studies, it subsequently grew to include Korean Studies as well. At present there are eight faculty members in the Centre. Several distinguished faculty who have now retired include the late Prof. Gargi Dutt, Prof. P.A.N. Murthy, Prof. G.P. Deshpande, Dr. Nranarayan Das, Prof. R.R. Krishnan and Prof. K.V. Kesavan. Besides, Dr. Madhu Bhalla served at the Centre in Chinese Studies Programme during 1994-2006. In addition, Ms. Kamlesh Jain and Dr. M. M. Kunju served the Centre as the Documentation Officers in Chinese and Japanese Studies respectively.

The academic curriculum covers both modern and contemporary facets of East Asia as each scholar specializes in an area of his/her interest in the region. The integrated course involves two semesters of classes at the M. Phil programme and a dissertation for the M. Phil and a thesis for Ph. D programme respectively. The central objective is to impart an interdisciplinary knowledge and understanding of history, foreign policy, government and politics, society and culture and political economy of the respective areas. Students can explore new and emerging themes such as East Asian regionalism, the evolving East Asian Community, the rise of China, resurgence of Japan and the prospects for reunification of the Korean peninsula. Additionally, the Centre lays great emphasis on the building of language skills. The background of scholars includes mostly from the social science disciplines; History, Political Science, Economics, Sociology, International Relations and language.

Several students of the centre have been recipients of prestigious research fellowships awarded by Japan Foundation, Mombusho (Ministry of Education, Government of Japan), Saburo Okita Memorial Fellowship, Nippon Foundation, Korea Foundation, Nehru Memorial Fellowship, and Fellowship from the Chinese and Taiwanese Governments. Besides, students from Japan receive fellowship from the Indian Council of Cultural Relations.
