Interfacial Colloidal Assembly Processing, Properties, and Applications

The book covers the fundamental understanding of interfacial colloidal assembly and describes how coupling of colloidal particles leading to various important applications. It begins with a detailed description of the central theories on colloidal assembly and technologies that drive interfacial colloidal assembly, followed by the elaboration of how the coupling of self-assembled particles providing exciting new properties. Later sections address the most important applications based on interfacial colloidal assembly technologies, ranging from structural color, plasmonic, to catalysis and biomedical applications.

Hongwei Duan is Associate Professor at the School of Chemical and Biomedical Engineering of Nanyang Technological University (NTU), Singapore. He received his B.S. and M.S degrees from Fudan University, then he completed his PhD degree at Max Planck Institute of Colloids and Interfaces and Postdam University in 2005. He pursuited his postdoctoral training in the Department of Biomedical Engineering at Emory University and Georgia Institute of Technology, USA. Before joining NTU in 2009, he was Assistant Professor (research track) at Emory University. His current research focuses on understanding surface/interface properties of micro- and nano-structures to achieve tailored optical, electronic, magnetic, catalytic, and structural properties for their biomedical and environmental applications.
