我们目前的应用程序的同步加速器为基础的光谱和显微镜环境相关的样品的例子。这些实验是在劳伦斯伯克利国家实验室的先进光源的分子环境科学光束线（11.0.2）上进行的。实例范围从使用X射线发射光谱法研究Pt（111）单晶表面上的水单层和使用环境压力光电子能谱法检查碱金属卤化物溶液/水蒸气界面，到使用扫描透射X射线光谱法研究锕系元素、河水生物膜、含Al胶体和矿物细菌悬浮液。我们的实验结果表明，在软X射线能量范围内的光谱学和显微镜是在现实条件下研究环境相关样品的极好工具，即，在环境温度下存在水或水蒸气。(c)2005 Elsevier B. V.保留所有权利。
We present examples of the application of synchrotron-based spectroscopies and microscopies to environmentally relevant samples. The experiments were performed at the molecular environmental science beamline (11.0.2) at the Advanced Light Source, Lawrence Berkeley National Laboratory. Examples range from the study of water monolayers on Pt(1 1 1) single crystal surfaces using X-ray emission spectroscopy and the examination of alkali halide solution/water vapor interfaces using ambient pressure photoemission spectroscopy, to the investigation of actinides, river water biofilms, Al-containing colloids and mineral-bacteria suspensions using scanning transmission X-ray spectromicroscopy. The results of our experiments show that spectroscopy and microscopy in the soft X-ray energy range are excellent tools for the investigation of environmentally relevant samples under realistic conditions, i.e., with water or water vapor present at ambient temperature.
