High yield mesoporous piezoelectric material for energy harvesting 

Synthesis of mesoporous Ferroelectric Barium Titanate (BaTiO3 poresize between 10 nm – 35 nm)  and it’s variations [ Ba1‐xSrxTiO3 where  x≤0.05; Ba1-xCax(Ti1-yZry)O3 where x≤0.15 ; y≤0.10 ],  Material can be in powder as well as in thin film form with layer thickness between 200 nm – 5  µm. Typical interest is to measure how much energy it can store under known applied force on an engineered materials. As from initial theoretical understanding (mostly in-practice works for Lead Zirconate Titanate) but it is unclear why Morphotropic Phase Boundary of non Pb system is inferior to that of the Pb-based system.​

Higher Studies (2003 - 2006) in Design Science from the University of Sydney, some of the involvement includes Bio-science instrumentation - design and interfacing for R&D. Worked (2011 - 2013) as full-time Technical Officer at University of Technology, Sydney (UTS), Faculty of Applied Physics and Advanced materials, provide research and teaching support for Measurement and Analysis of Physical Process, Applied Electronics & Interfacing. Visiting researcher (2014-2016) at the Institute of Superconductor and Electronic Materials (ISEM), University of Wollongong, Key contribution investigating Harvesting energy technique and its application. Visiting researcher (3 months, 2016) at National Institute of Material Science (NIMS), Japan – Key focus on learning technique on Mesoporous Materials. Currently awarded scholarship for Doctor of Philosophy at the AIBN, University of Queensland. 

Collaborations

Some key contribution in joint collaboration with Wollongong City Council and ISEM, University of Wollongong on a proposed project called INNOVATIVE WALKWAY ​
