Funding for an X-ray photoelectron spectrometer (XPS) is requested for measurement tasks in chemical analysis related to materials research. The following main requirements are important: (i) Daily, fully automated analysis of chemical binding states of air-sensitive materials and composites, as well as chemically modified surfaces, with lateral scanning and high spatial resolution to perform surface analysis. Imaging with simultaneous chemical information is paramount. (ii) Temperature-dependent measurement of reactive changes of interfaces and surfaces in battery materials and electrocatalysis, including the option to sputter. (iii) Ability to measure chemical states in electrochemical measurements in-situ. (iv) Depth analysis of materials to analyze burying layers, and possible measurement of density of states (valence band edges) of solids, in addition to measurements of energy gaps of molecules, surface defects and adsorbates.

要求为X射线光电子能谱仪提供资金，用于与材料研究有关的化学分析测量任务。（i）每天全自动分析对空气敏感的材料和复合材料以及化学改性表面的化学结合状态，采用横向扫描和高空间分辨率进行表面分析。具有同步化学信息的成像是至关重要的。(ii)电池材料和电催化中界面和表面反应变化的温度相关测量，包括溅射选项。(iii)能够在电化学测量中原位测量化学状态。(iv)对材料进行深度分析，以分析埋层，并可能测量固体的态密度（价带边缘），以及测量分子、表面缺陷和吸附物的能隙。
