Education: 

  • Ph.D. ­ University of Saarlandes, Germany ­ 2007 
  • M.Tech.­Mals Sci. & Engg., IIT Kharagpur ­ 2002
Teaching

Prof. Parida currently teaches advance level PG courses on aqueous corrosion and coatings. He has taught advance level courses on the electrochemical materials science to PG and Ph.D. students. Courses taught UG and PG levels are Corrosion and Protection of Materials, Thermodynamics and Kinetics of Corrosion, Protective Coatings, Aqueous corrosion and Electrochemical Materials Science. He is also conducting two corrosion labs, each for UG and PG students.

Research profile

Prof. Parida's research focus is on corrosion, coating and electrochemistry. In corrosion he is focussed on the understanding the mechanism of the atmospheric corrosion in metals and alloy development for the better corrosion protection. He is also focussed on the development and testing of both metallic (galvanized) and organic coatings. He has developed novel Zn­alloy galvanized coatings using indigenously developed hot­dip galvanization simulator. He is also working on the development of multifunctional organic coatings for corrosion protection, low­ surface energy and thermal shielding. Prof. Parida has also involved in the development and design of improved materials for oil and gas industry. He has developed and patented an economical, low corrosion, high density, clear completion fluid for HTHP oil wells. Currently, he is working on nanofluids design for EOR, which is focussed on tuning the surface wetting using earth­abundant nanomaterials. Prof. Parida has significantly worked on nanomaterials (nanocarbons, nano­oxides and trimetallic alloys) for electrochemical energy such as supercapacitor and electrocatalyst.

Research profile

The group of optoelectronic materials and devices are interested in developing semiconductor materials for optoelectronic devices, in particular halide perovskite materials. Halide perovskites have many interesting properties like high absorption coefficient, large charge carrier diffusion lengths, ease of synthesis, etc. However their real life applications are hindered due to the moisture instability and the lead toxicity. The group found zero­ dimensional perovskites to transform to 3D perovskites in the presence of moisture and remain to be stable under moist conditions, which lead to the stable perovskite solar cells. Since the transformation takes place in the presence of humidity, these were found to be useful in making self powered humidity sensors. To address the lead toxicity, the group is focussed on developing lead free perovskites and found that Cs2AgInCl6 doped with Bi3+ to be emitting a broad range with white light emission, making it a single source white light emitter.
