欢迎广大师生参加!华南软物质科学与技术高等研究院分子科学与工程学院2019年3月12日1.Linking rheological and mechanical properties of polymers to macromolecular structure内容摘要:The rheological behavior of polymer melts and solutions in processing influences their final mechanical properties. While it is known that rheology of polymer liquids is highly sensitive to their macromolecular structure, the underlying physics is not fully understood even for the simplest structure (i. e. linear polymers).In this presentation, we start from our latest work in which we show that conventional polymers can have unconventional properties by just changing their molecular conformation in processing. We point out the importance of sub-chain stretch of macromolecules, and then show how chain stretch is influenced by different macromolecular structures by comparing the rheological behavior between 1) polymer melts and solutions both with linear structure; 2) polymer melts with linear and star structures; and 3) polymer melts with random branched structure and blends with linear/ring structures. Interpretation of the rheological behavior will be compared with the results from small angle neutron scattering. Finally, we show the importance of fracture in polymer liquids which probably limits sub-chain stretch of macromolecules.The results presented shed light into the fascinating flow properties of polymers with different macromolecular structures and advance the state-of-the-art in polymer physics. At the same time, they also open the route for molecular design of biodegradable polymers.报告人简介:黄茜博士于2004年在浙江大学高分子系获得学士学位,2006年在丹麦科技大学高分子中心获得硕士学位。2010年获欧盟玛丽居里博士奖学金资助,于2013年4月在丹麦科技大学化工系获得博士学位。博士毕业后留校继续从事博士后、研究员的工作。其研究专注于高分子材料的机械性能、流变性能与分子结构的关系,已发表SCI论文33篇,其中包括PRL、ACS Macro Letters、Macromolecules等著名刊物,并多次在国际会议中做邀请报告。2. Hidden pathways in molecular and colloidal self-assembly revealed through the development of in situ characterization methods内容摘要:Molecular and colloidal self-assembly has been recognized as an important “bottom-up” approach to construct functional materials and self-organized systems for various applications. An understanding on the self-assembly pathways is significant for designing routes to the desired structures and the emergence of novel properties. However, it remains a great challenge to unveil the hidden pathways and translate states during self-assembly due to the difficulty of in situ characterizations, especially in complex hierarchical and/or multi-component systems. In this talk, we report our developments on in situ characterization methods and their effectiveness in revealing the hidden pathways during molecular and colloidal self-assembly. For instances, using in situ combined spectroscopies, we elucidate the transient structures during the self-assembly of organic cages and provide deep insights into the chiral amplification in multi-component supramolecular systems. Through a variety of in situ studies on molecular assembly, we discover and establish a new assembly mode that we name catalzyed assembly (catassembly) for its resemblance to catalysis. Finally, we highlight our discovery of the dynamic deformation of individual PbSe nanocrystals during colloidal assembly into superlattice through in-situ liquid-phase TEM. We show an unprecedented phenomenon that inorganic semiconductors are “soft materials” at the nanoscale.报告人简介:王宇博士于2009年毕业于南京大学基础学科强化部获得化学学士学位,于2016年毕业于厦门大学化学系获得博士学位。2016年5月至2017年8月在美国阿克伦大学从事博士后研究。2017年8月至今在美国加州大学伯克利分校从事博士后研究。长期从事分子与纳米粒子可控组装的方法学发展以及组装原位表征技术发展。利用原位光谱、原位X射线衍射、原位透射电子显微镜研究小分子、高分子、生物大分子、金属或半导体纳米粒子的组装行为和组装产物功能。已发表SCI论文15篇,其中以第一/共同第一作者或通讯作者发表论文9篇,包括三篇Nature Commun.以及 Chem.

Discrete Metal-Oxides: Functional Materials by Design内容摘要:With characteristics of chemically tunable structures and precisely controlled functionalities, polyoxometalates figure prominently in significant prospects, most notably catalysis, magnetism, biomedicine, and newly emerged proton conduction and lithium ion battery materials.i) The frontier of POMs based exclusively on noble metal centers (e.g., PdII, PtIII, and AuIII) as addenda is progressing rapidly, in particular polyoxopalladates, which possess great potential as noble metal-based catalysts. The first part of presentation is focused on the design and synthesis of guest metal ion-incorporated polyoxopalladates with fundamentally novel structures and physicochemical properties.ii) Recent developments on Lewis-acid functionalized POMs as enhanced proton conductors as well as polyoxometalate−cyclodextrin metal−organic frameworks with tunable structures and customized functions will be introduced in the second part.报告人简介:杨鹏博士于2016年6月在德国不来梅雅格布大学获得博士学位,期间师从著名多酸化学家Ulrich Kortz教授,主要从事贵金属钯多酸的合成、结构、主客体化学和催化性能研究。2016年11月-至今在沙特阿拉伯阿卜杜拉国王科技大学从事博士后研究,合作导师为Niveen M.
