    Investigation of Oxygen Sensing Capabilities and Relative Performance of Commonly Used Materials in A Combustion Environment
    (University of North Bengal, 2021-01) Roy, Chinmay; Chatterjee, Suman
    Several different oxygen sensitive materials have been synthesized and relative sensing capability was evaluated. Resistive response behaviors with varying oxygen gas concentration on TiO2, Nb2O5, WO3, La2CuO4, SrTiO3, SrCeO3 and La0.8Sr0.2MnO3 have been studied. The best operating temperature for maximum sensitivity was identified individually. The response at optimum temperature was calibrated for actual lean and rich combustion environment. The relative sensitivities with all pollutant gases present in combustion exhaust have been investigated in their relative concentration ranges.

    Array Of Nanostructured Sensor Elements For Determination of Tea Quality
    (University of North Bengal, 2021-01) Ghosh, Aparna; Roy, Chinmay; Chatterjee, Suman
    Detection of Volatile organic compounds is important for identification of flavour in different commercial organic products like Tea, Coffee, Wine, etc. The flavour components are detected through porous nanostructured Zinc Oxide (ZnO) sensing elements. This work shows the potential application of nanostructured gas sensor arrays for monitoring the quality of Indian tea.
