讲座内容:

  Utilizing the intense beam of Synchrotron radiation, researchers can conduct in-situ experiment of advanced materials tailored for energy and environmental applications. Synchrotron facilities offer a diverse range of techniques through various beamlines, providing structural and chemical insights across varying time and length scales. For instance, in-situ powder X-ray diffraction (PXRD) leverages the high intensity and resolution of synchrotron radiation to swiftly investigate the mechanisms of the advanced materials. Simultaneously, X-ray absorption spectroscopy (XAS) utilizes the adaptable energy properties of synchrotron radiation to reveal details about interatomic distances, bonding valences, and oxidation states of materials. This presentation will explore a series of case studies involving advanced materials conducted at the synchrotrons, highlighting the effectiveness of these methodologies.

  利用同步辐射的强烈光束,研究人员可以进行针对能源和环境应用定制的先进材料的原位实验。同步辐射设施通过不同的光束线提供多种技术,为研究人员提供跨越不同时间和长度尺度的结构和化学洞察力。例如,原位粉末X射线衍射(PXRD)利用同步辐射的高强度和分辨率,迅速研究先进材料的机制。同时,X射线吸收光谱(XAS)利用同步辐射的可调节能量特性,揭示材料的原子间距离、键合价和氧化状态等细节。本次演讲将探讨在同步辐射实验室进行的一系列先进材料案例研究,突显这些方法的有效性。
