Carbon dioxide a green house gas in the earth's atmosphere is abundantly available in the thin Martian atmosphere. The low Oxygen partial pressure, Ultraviolet radiation and low temperature make the conditions of mars hostile and life impossible. However researchers across the globe are consistently trying to exploit the conditions prevailing in mars and make it a planet suitable to support life. In the present research, a catalytic system suitable for Carbon dioxide splitting will be identified. Procedures will be developed and standardized for synthesis of the catalyst system that gives higher yields of Oxygen at lesser temperature, pressure and time. Ultraviolet photons will also be exploited for the photo electrochemical Carbon dioxide reduction. A detailed study on the activation and deactivation of the Catalyst complex will be carried out accounting the time required for the return from Mars. A suitable low pressure, low temperature reactor design suitable for Oxygen production from Carbon dioxide will also be proposed.

As a result of the investigation, a novel photo electrochemical Carbon dioxide reducing catalyst will be synthesized and characterized. A reactor suiting the developed optimized conditions will be designed.

Centre of Excellence for Energy Research (CEER) under the scheme establishment of centre of excellence in frontier areas of Science and Technology (FAST)

The Ministry of Human Resource and Development (MHRD), Government of India has conferred Centre of Excellence for Energy Research under the scheme of Establishment of Centre of Excellence in the Frontier Areas of Science and Technology (FAST) to our University in August 2014. The primary objective of the Centre is to provide sustainable energy solutions to the need for energy. Research at the Centre is taken up in four domains covering Solar Cells, Solar Thermal, Fuel Cells, and Bioenergy. Research initiatives has been already taken up in the development of polycrystalline silicon thin film PN junctions, Compound and Multi-junction photovoltaic's, Solid oxide fuel cells, Proton Exchange Membrane (PEM) Fuel Cells, Algal Biodiesel, Bioethanol from Macroalgal biomass and Biohydrogen from food waste.

India is the second largest in population next to China as per the U.N. World Population Prospects (2004 revision) using the medium fertility variant. Chennai is one of India's metropolitan with 200 yards in 15 zones. With a population of 8.7 million and 500 grams per capita per day of waste generated, the metropolitan has just two dump yards and eight transfer stations to dispose 4350 MT of waste generated per day. The dump yards at Kodungaiyur (LF1) and Perungudi (LF 2) have been in use for more than two decades as they were earlier part of the city non-residential limit. Due to its prolonged use the air, water and soil conditions of the neighboring areas of the two locations have been contaminated to the greatest extent. The project would focus on Managing and Monitoring Municipal Solid Waste Emissions using GIS Applications and Sensor Networks within 5 km radius of the two landfills

One densely populated area within 5 km distance of Perungudi and Kodungaiyur landfills will be identified as a source of Municipal solid waste generation. Non-spatially varied data like atmospheric gas concentration pressure, temperature, moisture content & temperature of cover soil will be recorded. CH4- CO2 sensors will be installed in all the transfer stations within the 5 km distance of both the dump yards. The data recorded by the sensor will be transmitted through wireless networks continuously as messages to a centralized Data centre web server through Open Geospatial Consortium Standard sensor web to report the GHG concentrations at the dump yards and at the transfer stations. The collected data transmitted to the data station will give an indication and an alarming increase of the GHG emissions let into the atmosphere. The data will definitely help in understanding the magnitude of Methane and Carbon-di-oxide emitted which can otherwise be trapped as a source of energy. Based on the continuous data acquired, and the health impact caused recommendations will be given.

Completed Projects:

**Production of Bio-diesel from different waste cooking oil sources

The sunflower oil and used oil (waste cooking oil) were analyzed for different physical properties such as relative density, viscosity and flash point as per the standard test methods. Both these oils were analyzed for their composition using Gas Chromatograph. Then, waste cooking oil obtained from frying different cooking process (Appalam frying , Poori Frying , Frying Vadai, Frying Fish, Chicken frying) and a mixed oil of all waste cooking oil (200ml) were taken one at a time in a glass reactor fitted with a magnetic stirrer, external heater, and condenser for transesterification process. The oil was heated to 50C in the glass reactor and NaoH (1gram) dissolved in methanol (60ml) was added. The contents were heated to 65-68C and the reflex condenser was used to condense the evaporated alcohol back into the reactor. The stirring helped to achieve uniformity of the reactants and the reaction continued for 2 hours. Then the reaction was stopped and the product was allowed to settle for 2-6 hours. The upper layer consisted of the biodiesel and alcohol and was separated from the bottom layer that contains glycerin and alcohol. The upper layer was then washed with equal amount of 2% salt water to remove excess alcohol and alkali and to facilitate easy separation of biodiesel. Finally the product was dried for 3 hours in hot air oven at 105C for 3 hours. Then the biodiesel was analyzed for fuel properties as per the standard test methods.

** Pollutant (NOx) Transport and Propagation Modeling from Stack attached to Diesel Fired Engines at GMR, Basin Bridge Power Plant, Chennai

The project is to study the level of contribution of the facility to the regional air quality.   The study includes meteorological study and air quality dispersion modeling using AERMOD with one year meteorological data.  The study also incorporates the terrain condition as well as taking into consideration of the water bodies near.  The study is to validate the present ambient air monitoring network that is being followed at the facility and to estimate the contribution under different operating conditions.

**Pollutant (NOx) Transport and Propagation Modeling from Stack attached to Diesel Fired Engines at Ascendas International Tech Park, Chennai  

The project is to study the level of contribution of the facility to the regional air quality.   The study includes meteorological study and air quality dispersion modeling using AERMOD with one year meteorological data.  The Metrological data from Sathyabama University and Nugambakkam Meteorology station was used to establish the micrometorological conditions present at the project site. Terrain condition along the 5 km radius of the project site is incorporated in the study.  The study is to validate the ambient air level contributed by the diesel fired engines along the IT Corridor and othe sensitive locations.
