1112日下午,廈門大學南強學術講座第1000講和1001講在盧嘉錫樓202會議室舉行。國際著名化學家、阿爾伯塔大學化學系教授、加拿大皇家學會徐雲潔院士和Wolfgang J?ger院士應邀訪問廈門大學,分別爲我校師生帶來題《Chirality Recognition, Transfer, and Amplification in Molecular Clusters and with Quantum Plasmons》和《Infrared and Microwave Spectroscopy of Molecules Embedded in Helium Nanodroplets》的精彩報告。學院副院長任斌教授主持了本場南強講座,學院謝兆雄院長和任斌副院長向徐教授和J?ger教授頒發了南強講座紀念牌並合影留念。




报告中,徐云洁教授以手性分子为核心,介绍了其課題組在分子水平上对手性分子表征方法以及行为机理方面的研究工作。其課題組利用chirped-pulse Fourier transform microwave (CP-FTMW)光譜考察了手性酸和醇在超聲噴射情況下的構型轉換和手性構建。利用圓二色譜和拉曼光學活性,他們探究了手性分子與分子間以及分子與原子之間的相互作用,也探究了非手性分子在水中和其它質子化溶劑中的特征。在他們最新的研究成果中,他們還提出了一種新的量子等離激元手性轉移和放大機理。這一機理解釋了在非共振條件下強烈誘導溶劑的ROA特征。在另外一場報告中,Wolfgang J?gerHelium nanodroplet spectroscopy为核心,首先介绍了其仪器和工作原理,并针对超低温体系下关于不对称顶部分子与氦原子逐步溶剂化研究的一些最新结果。 这些结果展现了微观超流动性的指标出现在小于20個氦原子的團簇尺寸上。



徐雲潔教授簡介:

   Yunjie Xu is a full professor and Tier I (Senior) Canada Research Chair in Chirality and Chirality Recognition in the Chemistry Department at the University of Alberta. Her research focuses characterizing chirality and chiral recognition/transfer/amplification/ at the molecular level. Her group not only applies vibrational circular dichroism, Raman optical activity, and rotational spectroscopy but also develops new IR-mass spectrometry techniques to study chirality related processes in the gas phase, in solution, and at the liquid-liquid interfaces. She has published 150 refereed articles in leading scientific journals including Science, Angew. Chem. Int. Ed., J. Am. Chem. Soc., J. Phys. Chem. Lett. and Phys. Rev. Lett.

   She has received many awards and honors including 2014 International Dr. Barbara Mez-Starck Prize for outstanding contributions in the field of experimental structural chemistry and molecular physics, 2015 International Mercator Fellowship from University of Freiburg, Germany, 2016 Clara Benson Award from Canadian Society for Chemistry, and 2019 Gerhard Herzberg Award from Canadian Society for Analytical Sciences and Spectroscopy. She was elected to the Fellowship of the Royal Society of Canada, Academy of Science in 2018.


Wolfgang J?ger教授簡介:

   Wolfgang J?ger received his PhD degree in Chemistry from the Christian Albrechts University in Kiel, Germany, in 1989. He joined the Department of Chemistry at the University of Alberta, Edmonton, Canada, in 1995 after spending time as postdoctoral fellow and research associate at the University of British Columbia, Vancouver, Canada. He was promoted to Associate Professor in 2001 and to the rank of Full Professor in 2003.

   Professor J?ger’s research is multifaceted and includes fundamental studies of intermolecular interactions using spectroscopic investigations of weakly bound complexes and clusters, development of atmospheric trace gas sensing techniques that utilize solid state infrared diode lasers, photoreaction chamber studies of aerosol formation, and design and fabrication of external cavity lasers using MEMS technology. His work has resulted in more than 180 publications thus far.

For his scientific achievements, Professor J?ger was awarded the NSERC Steacie Memorial Fellowship in 2002, in 2004 he became a Tier I Canada Research Chair in Cluster Science which was renewed in 2011, and in 2008 he was elected Fellow of the Royal Society of Canada. From 2009 to 2010, he spent a sabbatical year at the Fritz Haber Institute of the Max Planck Society in Berlin, Germany, which was funded by a prestigious Humboldt Fellowship.
