Data for Electron Microscopy Transfer System to Protect Atmosphere-sensitive Materials for Scanning Electron Microscopy Characterization

This data was collected to provide evidence for the successful ability of a novel scanning electron microscopy sample preparation method to protect highly atmosphere- and/or moisture-sensitive materials from undesired exposure to atmosphere. Initial proof-of-concept experiments were conducted with highly hygroscopic MgCl2 material exposed to controlled humidity environments and qualitative (photographs) and quantitative data (x-ray diffraction) were collected to compare samples that were prepared (1) with the use of the sample protection/preparation method (2) with no protections provided. Following this, hygroscopic BaO thin films were synthesized and prepared with the outlined method and characterized via scanning electron microscopy to demonstrate the functional application of the preparation technique.

本数据集的采集旨在为一种新型扫描电子显微镜（scanning electron microscopy）样品制备方法的防护效能提供实证支撑，该方法可使对大气和/或湿气高度敏感的材料免于非预期的大气暴露。研究首先以高吸湿性氯化镁（MgCl₂）为受试材料，将其暴露于可控湿度环境中，同时采集定性数据（照片）与定量数据（X射线衍射（x-ray diffraction）结果），以对比两组样品：(1) 采用该样品保护/制备方法处理的样品，以及(2) 未施加任何保护措施的样品。在此基础上，研究人员合成了吸湿性氧化钡（BaO）薄膜，并采用前述方法完成样品制备，随后通过扫描电子显微镜对其进行表征，以验证该制备技术的实际应用价值。
