Investigation into Advanced Materials Using Synchrotron Techniques

主講人 : Dr. Qinfen Gu

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.

利用同步輻射的強烈光束,研究人員可以進行針對能源和環(huán)境應(yīng)用定制的先進材料的原位實驗。同步輻射設(shè)施通過不同的光束線提供多種技術(shù),為研究人員提供跨越不同時間和長度尺度的結(jié)構(gòu)和化學(xué)洞察力。例如,原位粉末X射線衍射(PXRD)利用同步輻射的高強度和分辨率,迅速研究先進材料的機制。同時,X射線吸收光譜(XAS)利用同步輻射的可調(diào)節(jié)能量特性,揭示材料的原子間距離、鍵合價和氧化狀態(tài)等細節(jié)。本次演講將探討在同步輻射實驗室進行的一系列先進材料案例研究,突顯這些方法的有效性。
