We request funds to support acquisition of a new field emission, scanning electron microscope (FE-SEM) to be housed in the Institute of Geosciences at Johannes Gutenberg-Universität Mainz. This instrument will be equipped with detectors for energy dispersive spectroscopy (EDS), electron backscatter diffraction (EBSD), cathodoluminescence (CL), and a cryogenic stage for working with frozen samples. The combination of state-of-the-art fundamental and additional components will allow this instrument to be used for a diverse suite of analyses, such as examination of cryo-preserved biological/biogenic material, hydrated/water-containing labile materials such as hydrogels or clay minerals, fast and accurate mapping of the distribution of light elements, chemical quantification, orientation mapping, and various types of imaging at high resolution. The instrument will also be capable of operating at „low vacuum“ or „environmental“ conditions, so the samples we examine should not need conductive coatings, optimizing workflows and minimizing the chance that we will make them unsuitable for latter analses. Because of its wide-ranging capabilities, the instrument will be of interest to, and regularly used by, a number of different working groups throughout Universität Mainz, such as three members of the Institute of Geology, including two early career (tenure track) Professors, and researchers in both Chemistry and Physics. We are excited at the potential to bring such analytical capabilities to Mainz, where we expect its use and management by dynamic scientists with substantial experience in the afforementioned techniques to stimulate novel, and innovative research.

我们请求资金支持购买一台新的场发射扫描电子显微镜（FE-SEM），该显微镜将被安置在约翰内斯古腾堡-美因茨大学地球科学研究所。该仪器将配备用于能量色散光谱（EDS）、电子背散射衍射（EBSD）、阴极发光（CL）的检测器，以及用于处理冷冻样品的低温台。最先进的基本和附加组件的组合将允许该仪器用于各种分析套件，例如冷冻保存的生物/生物源材料，水合/含水不稳定材料（如水凝胶或粘土矿物）的检查，轻元素分布的快速准确映射，化学定量，取向映射以及各种类型的高分辨率成像。该仪器还能够在“低真空”或“环境”条件下运行，因此我们检查的样品不需要导电涂层，优化了工作流程，并最大限度地减少了我们使其不适合后续分析的机会。由于其广泛的功能，该仪器将感兴趣，并定期使用，一些不同的工作组在整个美因茨大学，如地质研究所的三名成员，包括两个早期职业（终身职位轨道）教授，和研究人员在化学和物理。我们对将这种分析能力带到美因茨的潜力感到兴奋，在那里，我们希望在上述技术方面具有丰富经验的充满活力的科学家能够使用和管理这种分析能力，以刺激新颖和创新的研究。
