Dr. Heng Zhai holds a PhD in Materials Science from the University of Manchester, UK, where his research was primarily focused on the preparation and application of functionalized graphene fiber materials for smart wearable technology and environmental remediation. With eight years of research experience at Manchester, Dr. Zhai specialized in techniques including wet spinning and electrospinning to produce graphene-based sensors exhibiting high sensitivity and robustness. His postdoctoral work further extended into electrochemistry and hydrogen energy, notably developing innovative proton exchange membrane fuel cells (PEMFCs) through advanced membrane electrode assembly techniques.
