中文简介: | X射线是100多年前发现的。从那以后,正如我们从体检或机场安全中所知道的那样,它们经常被用来“透视”材料并使可视化的隐藏对象可视化。在科学研究中,X射线是探测材料特性的宝贵工具,在生物学与健康科学,化学,物理学,地球与环境科学,考古学和文化遗产中已建立了广泛的应用。 X射线的特殊来源是产生极强辐射的大型电子加速器,特别适合用于纳米级材料的研究。他们使人们有可能更详细地研究催化剂,电池,太阳能电池和新型存储介质中的物理和化学过程,并回答有关地球内部感染,光合作用或过程的基本问题。 p> |
课程简介: | X-rays were discovered over 100 years ago. Since then they are often being used to “see through” materials and visualize hidden objects, as we know from medical examinations or airport security. In scientific research, X-rays are an invaluable tool to probe properties of materials and a vast range of applications has been established in biology and health science, chemistry, physics, earth and environmental science, archeology and cultural heritage. A special source of X-rays are large electron accelerators that generate extremely brilliant radiation, which is particularly suitable for the investigation of materials on a nanoscopic scale. They make it possible to investigate physical and chemical processes in catalysts, batteries, solar cells and novel storage media in great detail and to answer fundamental questions about infections, photosynthesis or processes in the Earth’s interior. |
关 键 词: | X射线; 大型电子加速器; 纳米级材料 |
