Systèmes nanocristallins à base d’oxydes métalliques pour la détection du dioxyde de carbone
Title (in English)
Metal Oxide Nanocrystalline systems for carbon dioxide Sensors
The project is on complex oxide systems including spinel ferrites and their response towards sensing low reactive gases like CO2. The work done include working with sensors of various forms including pellets made from nano crystalline powders, thick films prepared by screen printing and tape casting (using double doctor’s blade) and thin films deposited by RF sputtering and PLD. This project also aims to probe in to the sensing mechanisms in order to understand the reasons for the reactivity of certain metal oxide systems to specific gases. It aims to improve the performance of chemical sensor in terms of sensitivity, selectivity and stability. The interest will also be to reduce the response time , recovery time and the operating temperature of the sensor.

CIRIMAT laboratory Toulouse - France
The CIRIMAT (Centre Inter-universitaire de Recherche et d’Ingénierie des Matériaux) is a mixed unity of research (UMR CNRS 5085) from CNRS, University Paul Sabatier and Institut National Polytechnique of Toulouse. It was labelled “Institut Carnot” since 2006. The basic research goals of CIRIMAT include the synthesis and/or implementation of novel materials with specific properties, a better understanding of the interfaces in the development, transformation and use of the materials, the structure/properties connections and the enhancement of their performances. The research team involved in this project is the “Mixed Valence Oxide” team (leader Pr. A. BARNABE) which has a great experience in fine powders, bulk ceramics and thin films of oxides, especially spinel ferrites. This team has not only published many publications in this field but it has also patented different new spinel ferrites for several applications :
Optical recording media (see for instance French patent 2 832 251, 2001, World patent WO 03/042991 A1, 2003, which were licensed to a company for blu-ray disc fabrication),
Magneto-optical recording (see for instance US Patent 5,731,049, 1998, Japanese patent 244156/1998)
Infra-red detection bolometers (see for instance PCT n°050695, 2004, World patent WO 2008/084158 A3)
The team is now involved in the study of the oxide-gas interaction and in the used of complex oxides as chemical sensors. This activity has already been the subjects of several publications (see for instance references [5, 61, 52, 53, 54]). Due to the big potential development of this activity, the team wants to increase its activity in this field. The cooperation with the Indian partners, which are also interested in similar materials but with complementary approaches, will contribute very positively to the development of the research on complex oxides for sensors.
As it was demonstrated before, the partners have real skills for original oxides elaboration. The project will try to take benefit of their complementarity :
elaboration of precursors from oxalic route by in France, from combustion process in India, sintering of porous bulk ceramics (conventional and SPS in France), thick films (tape casting in India, combination of porous materials with thin films of CuO (sputtering in France, PLD in India), study of gas sensing mechanism with different approaches.
Indian Institute of Technology - Mumbai
Established in 1958, IIT Bombay has a total of 14 Academic Departments, 10 Centres, two schools and three Interdisciplinary Programmes. It is recognized worldwide as a leader in the field of engineering education and research. It is reputed for the quality of its faculty and the outstanding calibre of students graduating from its undergraduate and postgraduate programmes. Two departments are involved in the MONaSens project :
The Department of Metallurgical Engineering & Materials Science (Pr. N. VENKATARAMANI) emerged out of a merger between the erstwhile Metallurgical Engineering Department, and the interdisciplinary program on Materials Science. Today, it is one of the best departments in the country for materials education and research in areas like thin films and devices, electronic materials, mechanical behavior of materials, advanced composites, surface engineering, nanomaterials and materials modeling and design. The faculty members address various important and challenging issues, at the forefront of materials science and technology. The underlying philosophy of this department is to apply principles of basic sciences and engineering to understand the behavior of materials, and then to apply this understanding to develop technologies of national importance in energy, defense, health care, space and agriculture.
The Physics Department (Pr. S. PRASAD) has a tradition of vibrant teaching and offers many research programs. Research work in the department encompasses Condensed Matter Physics, Laser & Optics, Nuclear Physics, High Energy Physics and Statistical Physics in the theoretical as well as experimental domains. Pr. S. PRASAD also has PLD unit which we access to make thin films. Additionally Pr N. VENKATARAMANI do measure magnetic properties in the case of ferrite thin films in the Physics Dept. and discuss, analyze these results with Pr. S. PRASAD. Ferrite thin films being magnetic reveal some important aspects through study of magnetic properties. Particularly relevant here are some cation distributions in the nano crystalline form, which is useful in the gas sensing features as well.
Pr. S. PRASAD and Pr. N. VENKATARAMANI have been working together on research projects over twenty years.
Agence Nationale de la Recherche (ANR)
L’Agence Nationale de la Recherche (ANR) was created in February 2005 as a public interest grouping. With effect from 1 January 2007 ANR was designated as a Public Administrative Establishment. ANR provides funding for project-based research in all fields of science – for both basic and applied research – to public research organizations, universities and private companies. Since 2010, ANR has also been the principal operator of the Investments for the Future program in the field of higher education and research. In this role it ensures the selection, funding and monitoring of projects relating to the centers of excellence, health, biotechnologies, and the transfer of technology and the creation of value from research.
Department of Science and Technology (DST)
Department of Science & Technology (DST) was established in May 1971 to organize, promote and coordinate science & technology development and research activities in India. DST plays a pivotal role in promotion of science & technology in the country. It has a wide array of activities ranging from promoting high end basic research and development of cutting edge technologies on one hand, and, to service the technological requirements of the common man through development of appropriate skills and technologies on the other.
