　　报告人简介：To NGAI now is Professor in the Department of chemistry, Assistant Dean (Research) of the Faculty at the Chinese University of Hong Kong (CUHK), and Fellow of the Royal Society of Chemistry (FRSC). He received his B.Sc. degree with first class honours and PhD in chemistry from CUHK in 1999 and 2003 respectively. He moved to BASF (Ludwigshafen, Germany) in 2003 as the postdoctoral fellow for two years. After a short postdoctoral training in the Chemistry Department at the University of Minnesota in 2005, he joined the Chemistry Department at CUHK in 2006 as a research assistant professor. He has been appointed as an assistant professor in 2008, and promoted to associate professor in 2012. In 2017, he was promoted to Professor. His current research interests center around the colloids, surface chemistry, polymers and soft matter.

　　报告摘要：Microgels stand out as compelling alternatives to traditional emulsifiers in Pickering emulsions, owing to their unique deformability and responsiveness, distinguishing them from rigid particles and conventional surfactants. In this talk, To NGAI will provide an overview of recent advancements in microgel synthesis and the stabilization of Pickering emulsions using microgels. Additionally, he will discuss the underlying stabilization mechanisms of microgel-stabilized emulsions, elucidating the influencing factors such as microgel properties, environmental conditions, and interfacial structures that significantly impact emulsion stability. Given these recent achievements, he will highlight the promising applications associated with diverse Pickering emulsion systems stabilized by tailored microgels, including interfacial catalysis, functional foods, vaccine adjuvants, stimuli-responsive colloidosomes and droplet manipulation.
