The phenomenon of adsorption of colloidal particles at fluid interfaces to stabilize emulsions have been known for more than a century. Today, particle-stabilized emulsions/foams, often referred to as Pickering emulsions, are receiving growing attention as they are encountered in oil recovery and have long been used in personal care products and food industry. In this talk, a brief overview of the development of various particles is given for Pickering emulsion stabilization. The functional materials capable of being prepared by templating from Pickering emulsion then will be introduced and discussed.

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.
