Supercapacitors

Dr. Syam G. Krishnan is a Postdoctoral Research Fellow at Queensland University of Technology (QUT), Australia. With a research background in nanomaterials for supercapacitors, Dr. Krishnan’s research focuses on synthesis, tailored morphology, and conductivity of metal oxides and their composites, ternary metal cobaltites, polymer nanocomposites, and activated carbon for supercapacitors. At QUT, he is working on recycling of battery materials for supercapacitors, metal-ion batteries, and wearable electronics. Prior to joining QUT, Dr. Krishnan worked as a Research Fellow in the Graphene and Advanced 2D Materials Research Group (GAMRG), at Sunway University, Malaysia. He has co-authored approx. 30 journal papers, co-authored 2 book chapters, and delivered several invited talks at conferences. Dr. David (Hong Duc) Pham is a Postdoctoral Research Fellow at the Centre for Materials Science, School of Chemistry and Physics, Queensland University of Technology (QUT), Australia. He obtained a Master’s degree in biofuel production at Pukyong National University (PKNU), Republic of Korea, before joining QUT to work on the development of novel organic semiconductor materials for perovskite solar cells for his PhD, where his PhD thesis was honoured by the Executive Dean’s commendation for outstanding doctoral thesis award. He gained a postdoctoral position in 2019, and recently obtained the QUT Early Career Researcher Scheme 2021. Dr. Pham’s research interests are in developing new materials and green solvents for energy conversion and storage devices, with special emphasis on potassium-ion batteries and nanogenerators. He has authored or co-authored approx. 35 peer-reviewed research papers, and is a member of the Royal Australian Chemical Institute (RACI). Deepak P. Dubal is a Professor at Queensland University of Technology, Brisbane, Australia. With an extensive background in the field of nanomaterials for clean energy conversion and storage systems, Professor Dubal’s current research is focused on designing and engineering functional materials such as new oxides/nitrides, polyoxometalates (POMs), and conducting polymers and their hybrids for energy storage applications, with special emphasis on supercapacitors, Li-ion batteries, and beyond Li-ion batteries. He is working to develop an integrated system as a self-charging power source for wearable electronics and implantable medical devices.
