题目一：PETRA III – Overview and scientific capabilities

报告人：Florian Bertram

单位：Deutsches Elektronen-Synchotron DESY

报告摘要：PETRA III is a third-generation high energy synchrotron radiation source located at Deutsches Elektronen-Synchotron DESY in Hamburg, Germany. Operating at 6 GeV PETRA III provides synchrotron radiation in the energy range from approx. 4 eV up to 150 keV at 25 specialized beamlines. This talk will give an overview of PETRA III and the available beamlines with a special emphasis on beamlines for X-ray diffraction experiments as well as the beamlines for extreme condition research, including recent research highlights.

个人简介：Dr. Florian Bertram就职于德国汉堡德国电子同步辐射加速器中心（DESY）。是高能同步辐射源PETRA III上高分辨率衍射光束线站P08和原位衍射与成像光束线站P23的线站负责人，研究聚焦于超薄膜的结构特性分析。

题目二：X射线散射技术在纳米材料表征上的应用

报告人：孙笑

单位：德国科布伦茨大学

报告摘要：This talk will focus on several X-ray Scattering techniques, such as Small-angle X-ray Scattering (SAXS), total Scattering with Pair Distribution Function analysis (PDF), X-ray Absorption Spectroscopy (XAS) provided at different beamlines at PETRA III, DESY in Hamburg, Germany. In complimentary to electron microscopy methods, which provide local information, X-ray techniques provide a macroscopic overview of nanomaterials. This makes them ideal for in-situ investigations during reaction, including nanoparticles under high pressure.
