RESEARCH
Our research and development focus on Surface Science and Engineering of interfacial interactions, surface functionality enhancing and enabling, and engineering implementations targeting primarily three areas: sustainable surface engineering, energy and resource regenerations, and medical devices.1. Sustainable Surface Engineering: Our research in this area focuses on the development of environmentally sustainable and economically viable chemical, electrochemical, and hybrid electrolytic and vapour deposition technologies assisted with plasma, laser and sonication. Specific research conducted includes surface modification of lightweight materials (magnesium, titanium, aluminum etc.) and additively manufactured products for a broad spectrum of applications such as vehicular lightweighting for fuel efficiency and GHG emission reduction, surface functionality enhancement and enabling for 3D printed products.
2. Energy and Resource Regenerations: In the realm of energy and resource regenerations, we conduct research on surface engineering of key components for energy storage systems (supercapacitors, batteries and solar cells), large waste-to-energy systems, and biomass power generation systems with respect to system performance and safety. We also carry out system development for echelon utilization and materials regeneration of spent high-power batteries.
3. Medical Devices: The prevalence of thigh pain after total hip replacement remains an unacceptable complaint by some patients. Reasons for this include unstable fibrous fixation, differences in the degree of elasticity for the prosthesis material and bone, fatigue fracture, relative motion across the interface between the implants and the surrounding tissues causing excessive stress at the implant/body tissue interfaces, and postsurgical infections. Our research is directed to develop new ‘Chemo-Biomimetic” technologies forming bioactive surfaces to enhance the biochemical compatibility, incorporation of hormone, protein and antibiotics into the implant, fabrication of new nanocomposites with improved biomechanical compatibility, and formation of nano-grain sized biocompatible implant surface & subsurface features to promote postsurgical healing and enhance implant/bone integration and performance.
