Senior Assistant Professor, Faculty of Integrated Technologies
I have completed my Bachelor, Masters and Master of Philosophy in Physics from Jahangirnagar University, Bangladesh. My M.Phil. project was to characterize superconducting ceramic oxide materials by neutron diffraction. Then I moved to Sweden for my PhD to work in Materials Chemistry with Professor Sten Eriksson at Goteborgs Universitet. During my PhD I was working on double perovskite type materials development for artificial memory applications. After completion of my PhD, I worked one year at the University of Uppsala as a postdoctoral Research fellow working on the neutron diffraction studies of perovskite type materials for magnetic applications. Rietveld refinement of neutron diffraction data using Fullprof or GSAS was one of my main work. Then I moved to UK to work in the University of St-Andrews with Professor John Irvine. In St-Andrews, I was working of the development of electrode materials for Solid Oxide Fuel Cells. Electrochemical characterization and application in real fuel cell was major part of my work.

The conjunction of biomass gasification with solid oxide fuel cells (SOFCs) is a promising and forthcoming possibility for electricity and heat cogeneration along with profound environmental and socioeconomic benefits. This is in-line with one of the strategies to achieve GDP target of 63% contibution from the non oil and gas sector, i.e. innovation technology and creative industry. Solid oxide fuel cells (SOFC) are in the commercialization phase and, therefore, would be interesting to integrate with biomass gasification technologies to have a single and highly efficient system; combining the benefits of each system to establish a new technology. Biomass fuelled integrated SOFC system is one of the key energy technologies of the future since it combines the merits of renewable energy sources and hydrogen energy systems. Together with an integrated gasification plant that gasifies wood chips in a two-step gasification process, electricity and heat will be produced in an environmentally friendly way. The produced heat will be used for water purification. This is a novel technique to produce electricity and driniking water, and lots of space to do research and development.
Supercapacitor is an energy storage device that attempts to combine the high power density of a capacitor with the high energy density of a battery. Conventional supercapacitors use carbon based electrodes, mostly graphite. In recent years, alternatives such as carbon nanotubes, graphene, and other nanostructured materials have been considered to construct supercapacitor electrodes.
There are many ceramics that has been investigated as potential anode materials and many of which are perovskite-type structures. Recently, double perovskites with the general formula A2BB/O6 have also been reported to be good anode materials.Changing of the A and B-site cations has strong effect not only on its structural and electrochemical properties but also on the performance in fuel cell applications. Many compositions have already been studied and many more is on-going to find the best composition. Huang et al.  reported that the double perovskite Sr2MgMoO6-Î´ has been an excellent anode as it yielded high power density and has high sulfur tolerance. Bernuy LÏŒpez et al. shows high redox and 1200 Â°C under 5% H2/Ar reducing and stability and up to 1000 Â°C under 5% H2/N2 conditions. However, recent work done by Bi et al. shows that the material possessed very poor intrinsic catalytic activity for oxidation of both H2 and CH4 in the absence of Pt mesh/paste as current collector. On the other hand, Vasala et al. has investigated the effects of W and Nb substitution on active element Mo in the structure and electrical properties. Niobium compounds are well known to show an excellent catalytic activity for different reactions, being used as active catalysts for methane oxidation. To our knowledge, no work has been done on the double perovskite material Sr2FeNbO6-Î´ as an anode in the application of solid oxide fuel cell. Fe and Ti ions are stable cations and have good stability of the perovskite structure against reduction. . Y.-H. Huang, R. I. Dass, Z.-L. Xing, and J. B.
