Abstract:
Understanding how complex hybrid materials are organized through synergistic self-assembly and chemical synthesis across extended and multiple length scale is of growing interest in materials science and technologies. This talk will highlight some recent advances in the synthetic construction of macroscopic bulk materials under equilibrium conditions. We focus on organization of higher-order architectures from inorganic nanophases using cellulose self-assembly to coordinate the nucleation, growth and transformation. We examine a range of synthetic modalities that give rise to extended length-scale organization of matter spanning from molecular to macroscopic level.Of particular interest is a helical superstructure of cellulose to facilitate its use as a functional nano-building block for extended-scale structuration with anisotropic properties and chiroptical activity. Key elements of the constructional codes associated with these processes are identified based on existing knowledge, and presented as a practical guideline for the organization of advanced nanomaterials that hold promising potentials in photonic, environmental and energy applications.

About the speaker:
Yan Xu received her PhD from Imperial College London, UK and postdoctoral training at the Nantional University of Singapore. After 5 years of academic career with Nanyang Technological University of Singapore and 10 years of industry experience, she is currently a full professor in the State Key Lab of Inorganic Synthesis and Preparative Chemistry, Jilin University, China. Her current research evolves around Bioinspired Organized Matter. It seeks to advance a new integrative approach to the synthetic construction of macroscale bulk materials with embedded complexity, higher-order architectures and integrated functions, and emergence of complex forms of organized matter, and collective behavior in a nanomicro system. She has coauthored two books published by ELSEVIER and World Scientic, holds several international and chinese patents, and published over 80 papers in high impact science journals including Adv. Mater., Angew Chem. Int. Ed.
