1. Occlusion of nanoparticles within inorganic crystals（Dr. Yin NING）

Abstract：

In Nature, some organisms can manipulate the formation of biominerals by incorporating biomacromolecules (e.g. proteins, albeit at very low levels of loading) within the inorganic matrix and thus achieve enhanced mechanical properties for optimized functions (e.g. hardness and toughness). This biogenic strategy has inspired scientists to design and prepare synthetic biomimetic materials with high performance. However, relevant research in the past was mainly focused on soluble (macro)molecules. Occlusion of nanoparticles during crystal formation has been rarely studied to date. Indeed, progress in this field has mainly relied on empirical trial-and-error experiments because little is known about what parameters dictate nanoparticle occlusion as well as occlusion mechanism itself. This severely hinders the development of research in this area. In this talk, I will present the precise synthesis of various series of nanoparticles with controlled size, morphology, composition and structure via polymerization-induced self-assembly (PISA), and subsequently elucidate the effect of these parameters on nanoparticle occlusion and the underlying mechanism.

Brief Biography：

Dr. Yin Ning obtained his Bachelor’s degree in polymer materials and engineering from Ludong University in 2010 and Master’s degree in materials science from South China University of Technology in 2013. He achieved his PhD degree at the University of Sheffield in 2016. He then continued as a postdoctoral researcher at the same university. In the past five years or so, Dr. Yin Ning has dedicated himself to conducting fundamental research on nanoparticle occlusion within inorganic crystals, aiming to precisely synthesize well-defined nanoparticles with controlled size, morphology, composition and structure, and subsequently elucidate the effect of these parameters on nanoparticle occlusion and the underlying mechanism. In addition, he also aims to gain a better understanding of biomineralization and provides fundamental guidelines to extend this methodology to the preparation of new functional materials. So far, he has published 22 peer-reviewed research papers, including 12 first/corresponding authored publications (e.g. 3 JACS, 2 Angew. Chem. Int. Ed., 2 Chem. Sci., etc). In addition, he has co-authored two patents and a book chapter.
