About Me: I am highly motivated to build up my career as a researcher. With a view to achieving my goal, currently I am working on different research projects. I believe this to be a great opportunity to attain invaluable experience and practical knowledge in the research field which will immensely help my growth as a research scholar.

Research Interest: Nanotechnology, Energy Harvesting and Conversion, Magnetic materials

Research Projects:

So far, I have contributed to the following research projects.

1.   Synthesis of MoS2 incorporated GaFeO3 nanocomposites and investigation of their structural and magnetoresistive properties along with photocatalytic dye degradation and hydrogen production ability

Summary:  In this research project, multiferroic GaFeO3 nanoparticles will be synthesized using sol-gel method and their structural and magnetoresistive properties will be thoroughly investigated. It is also intended to incorporate MoS2 with synthesized GaFeO3 nanoparticles using hydrothermal technique to investigate the optical properties as well as photocatalytic dye degradation and solar hydrogen production rate of the as-prepared GaFeO3-MoS2 nanocomposites.

2. Synthesis and characterization of MoS2 based nanocomposites for solar energy applications 

Summary:  In this research project, MoSincorporated α-Fe2O3/ZnO nanocomposite has been synthesized adapting facile low temperature hydrothermal technique. The prepared nanocomposite with excellent structural, morphological and photocatalytic properties has demonstrated great performance in dye degradation and photocatalytic hydrogen production via water splitting.

3. Synthesis of doped double-layered perovskite manganites at inert atmosphere and investigation of their structural, morphological and magnetic properties

Summary: In this project, Gd doped double-layered perovskite manganites La1.7Gd0.3SrMn2O7 and La1.4Gd0.6SrMn2O7 have been synthesized at inert atmosphere and further, their structural and magnetic characterizations have been performed. The as-synthesized dilute amount of Gd doped La1.7Gd0.3SrMn2O7 manganite with enhanced ferromagnetic softness may have potential applications in numerous fields.

4. Feasibility studies on deploying a self-contained solar-hydraulic pilot power plant in a rural area in Bangladesh 

Summary: This project has been funded by the Global Challenges Research Fund (GCRF) and conducted by the University of Glasgow, UK in collaboration with Bangladesh University of Engineering and Technology (BUET). In this pilot project, feasibility studies have been performed for establishing a novel hybrid power plant in hilly regions of Bangladesh with a view to utilizing three renewable energy resources i.e. hydroelectricity, solar and wind energy simultaneously.
