美国加州大学圣地亚哥分校Ying Shirley Meng教授应邀到我校澳门新葡8455最新网站进行学术交流

  

  

  2017年9月2日,应我校澳门新葡8455最新网站吴锋教授团队的邀请,美国加州大学圣地亚哥分校Ying Shirley Meng教授在5号教学楼906会议室做了一场“21世纪学科前沿”系列学术讲座,题为“Advanced Materials Design, Diagnosis and Operando Characterization for Enabling High Energy Long Life Rechargeable Batteries”。 高比能长寿命二次电池是促进低碳经济发展的重要支撑。在了解材料在储能过程中结构变化的机制方面,无论是对于科学家,还是对于工程师,先进的材料表征技术都是必不可少的手段。报告中,Ying Shirley Meng教授先容了如何利用具有高空间分辨率的扫描电镜(SEM)、电子能量损失谱 (STEM/EELS) 等方法对电池材料的表面、晶界、相界等进行纳米成像和化学分析;进一步结合第一性原理计算,能够对构效关系实现比过去更为深入的理解。此外,采用耦合的X射线成像,可以帮助识别分别率为10nm的电子密度等信息,实现对单颗粒正极材料的现场检测。借助新型的电子成像和X射线成像技术,有望为深入研究材料的反应机理和寻找适宜的解决方案提供新的思路。

  报告嘉宾概况: Dr. Y. Shirley Meng received her Ph.D. in Advance Materials for Micro & Nano Systems from the Singapore-MIT Alliance in 2005, after which she worked as a postdoc research fellow and became a research scientist at MIT. Shirley is currently professor of Nano Engineering, University of California San Diego (UCSD). Dr. Meng’s research focuses on the direct integration of experimental techniques with first principles computation modeling for developing new intercalation compounds for electrochemical energy storage. She is the founding Director of Sustainable Power and Energy Center (SPEC), consisting faculty members from interdisciplinary fields, who all focus on making breakthroughs in distributed energy generation, storage and the accompanying integration-management systems. Dr. Meng is the principle investigator of the research group - Laboratory for Energy Storage and Conversion (LESC). She received several prestigious awards, including C.W. Tobias Young Investigator Award of the Electrochemical Society, BASF Volkswagen Electrochemistry Science Award, Frontier of Innovation Award and NSF CAREER Award. Dr. Meng is the author and co-author of more than 130 peer-reviewed journal articles, 1 book chapter and four patents.
