After experiencing the pain of losing a loved one to lung cancer at the tender age of 10 years old, Assistant Professor Edison Ang turned the emotional setback into an inspiration. It spurred him to complete his Doctor in Philosophy (PhD), and at the age of 33, he become an assistant professor at the National Institute of Education, Nanyang Technological University, Singapore (NIE NTU, Singapore). This inspiration also led him to aspire to continually undertake high-level research and development, contribute to humanity, and nurture the next generation of youth. “I believe that the younger generation is humanity’s greatest asset, and they are also the future of sustainability,” shared Assistant Professor Ang. To this day, this belief has shaped his conviction towards research in order to empower teachers to inspire the next generation of young scientists and engineers whom he believed would bring about change to the world.
As a researcher at NIE NTU, Assistant Professor Ang is deeply interested in a wide range of nanoscale materials – particularly two-dimensional (2D) nanosheets that are 100,000 times thinner than the hair of human, and graphene, which can be found in pencil lead. “Understanding the properties of these nanomaterials has significant technological implications in energy conversion and storage, water purification, and food and beverage implementations,” quipped Assistant Professor Ang. His research activities include nanomaterial design and fabrication, surface modification, coating, arrays and thin-film fabrications, defect engineering, 3D printed materials, developing sustainable materials, materials characterization, and device design. “My team studies the fundamentals of nanomaterials, establish low-cost processing methods, and resolve critical issues in a realworld application,” he shared.
In 2021, Assistant Professor Ang successfully applied for external funding to support two of his research projects: 3D-Printing Membrane for Industrial Wastewater Treatment and 3D-Printed Electrode for High-Energy Rechargeable Batteries. “3D printing technology is automated, scalable, and saves time and money in manufacturing,” explained Assistant Professor Ang. “We can print complex shapes without the use of a mould. We can also print multiple parts with precise dimensions in a single build with different design." However, such technologies are not without challenges. One of the major challenges of implementing nanomaterials for rechargeable batteries and membrane filtration applications is the lack of structural design and controllable dimension. According to Assistant Professor Ang, this limits their optimum and consistent performance for practical application. “The advancement of 3D printing technology has revolutionised the customization of functional materials. However, we must not lose sight of the importance of remaining sustainable while doing so", cautioned Assistant Professor Ang.
Reflecting upon his research journey in 2D nanomaterials, Assistant Professor Ang shared that in 2020, he started Nanotech Lab and had since developed a unique 2D nanomaterials ink (graphene), which can be 3D printed, paving the way for new industrial opportunities in the fields of rechargeable batteries and membrane filtering. Extending his gratitude for the support he had received from his collaborators, Assistant Professor Ang added, “These amazing works have resulted in two provisional patents.” Following these achievements, Assistant Professor Ang was awarded Outstanding ASIAN Science Diplomat Award and Vebleo Fellow Award in 2021 in recognition of his outstanding research work and leadership in the field of science, engineering and technology.
In 2022, he was awarded the Sabic Young Professional Award by the American Institute of Chemical Engineers for his outstanding and internationally recognized contributions in particle technology for young professionals under 45 years old. Also, he was invited by the International Association of Advanced Materials to give a Young Scientist Medal Lecture on “Chemistry of Two-Dimensional Nanomaterials for Energy Storage and Membrane Technology” to showcase his 3D printed works. As a young faculty member, he was also elected by the prestigious publishers, for instance, Elsevier, as an Early Career Editorial Board Member of Chemical Engineering Journal, Springer Nature, as a Young Editorial Board Member of Journal of Leather Science and Engineering, and Frontiers, as Reviewer Editorial Board Member of Frontiers in Chemical Engineering for Separation Processes.
To budding postgraduate students, he has this to share, “Before beginning a graduate research programme, consider your life purpose. My life purpose of making a difference in the world through research and development motivates me to get out of bed every morning. Find a passion that inspires you and makes your life worth living for.”
