About Dibyaranjan RoutSwetapadma Praharaj

Swetapadma Praharaj is currently working as Associate Professor in the Department of Physics School of Applied Sciences Kalinga Institute of Industrial Technology (KIIT) Deemed to be University Bhubaneswar Odisha India. She obtained her M.Tech in Metallurgical and Materials Engineering from the NationalInstitute of Technology (NIT) Roukela and was awarded with the Institutes silver medal for her performance. Thereafter she completed her PhD in Physics at KIIT during which she honed her expertise on the development of lead-free piezoceramics and improvement of their figures of merit. To her credit she has published in 30 peer-reviewed journals.Dr. Praharaj applies her expertise to best tailor the functionalities of eco-friendly ceramic materials that are the materials of choice in electronic components and hightech machines. She has a keen interest in developing high-strain and temperature-stable high Tc ceramics (applicable in actuators sensors and capacitors) by compositional engineering. She is proficient in evaluating the performance-based figures of merit of materials in terms of S-E P-E Dielectric and impedance spectroscopy. Currently Dr. Praharaj is working on designing energy storage and harvesting devices using lead-free piezoelectric and supercapacitor (electrode) materials.Dibyaranjan Rout is currently working as Associate Professor at the School of Applied Sciences (Physics) Kalinga Institute of Industrial Technology (KIIT) Deemed to be University. He obtained his PhD in Physics from the Indian Institute of Technology (IIT) Madras and subsequently took a postdoctoral position in the Department of Materials Science and Engineering Korea Advanced Institute of Science and Technology Korea. He also served as a Research Assistant Professor in the same institute for two years. To his credit he has published more than fifty papers in peer-reviewed journals. Under his supervision five PhDs and ten master's theses have been awarded.Dr. Routs research interest encompasses the structureprocessproperty relationships exhibited by functional/ smart materials particularly lead-free piezoelectric/multiferroic/high-Tc relaxor materials. He is keen to design and develop such novel and eco-friendly materials in the form of bulk ceramics nanoparticles nanostructures thick films fibers and nanocomposites using ease and cost-effective processes (solid state reaction soft chemical spray pyrolysis electrospinning) with adequate figures of merit suitable for industrial applications (specially actuators multi-layer ceramic capacitors energy storage/harvesting and dye degradation).
