Biography:

To NGAI is now a Professor in the Department of Chemistry, Assistant Dean (Research) of the Faculty of Science at The Chinese University of Hong Kong (CUHK), and a Fellow of the Royal Society of Chemistry (FRSC). He obtained his B.Sc. degree with first class honours and Ph.D. in Chemistry from CUHK in 1999 and 2003, respectively. He then pursued his postdoctoral training at BASF in Germany and Minnesota, USA before joining CUHK as a Research Assistant Professor in 2006. 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. Prof. Ngai have published over 200 papers with total citations of ~8600 and an h-index of 52 (Google Scholar). He received the Chemical Society of Japan (CSJ) Lectureship Award 2020, and the Paul J. Flory Research Prize 2023 at the 29th Polychar World Forum on Advanced Materials in Nice, France.

Abstract:

Microgels stand out as compelling alternatives to traditional emulsifiers in Pickering emulsions, owing to their unique deformability and responsiveness. In this talk, I will provide an overview of recent advancements in microgel synthesis and the stabilization of Pickering emulsions using microgels. Additionally, I 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, I will highlight the promising applications associated with diverse Pickering emulsion systems stabilized by tailored microgels.
