摘要

基于倾斜系列能量色散 X 射线光谱（EDX）图的电子断层成像技术可有效分析含有多种元素的材料的三维元素分布。然而，EDX 图谱需要较高的电子剂量，因此将 EDX 层析技术应用于对电子束敏感的材料具有挑战性。在这项研究中，我们展示了含水防晒霜的冷冻转移EDX层析成像，这种防晒霜在电子束照射下很容易溶解。在最佳实验条件下，成功地观察到了防晒霜中氧化钛颗粒、氧化锌颗粒、硅油和乳化水颗粒的三维分散状态。这项研究为了解防晒霜成分的分散状态提供了宝贵的见解，这对改进产品设计和性能至关重要。

Cryo-transfer energy dispersive X-ray spectroscopic tomography for morphological and elemental analysis of moisture-containing sunscreen creams

Electron tomography based on a tilt-series of energy dispersive X-ray spectroscopy (EDX) maps is effective for analyzing the three-dimensional elemental distribution of materials containing multiple elements. However, EDX mapping requires a high electron dose, making it challenging to apply EDX tomography to electron-beam-sensitive materials. In this study, we demonstrated cryo-transfer EDX tomography of water-containing sunscreen cream, which easily dissolves under electron beam irradiation. Under optimal experimental conditions, the three-dimensional dispersion state of titanium oxide particles, zinc oxide particles, silicone oil, and emulsified water particles in the sunscreen cream was successfully visualized. This study provides valuable insights into the dispersion state of sunscreen components, which is crucial for improving product design and performance.

期刊介绍： Micron is an interdisciplinary forum for all work that involves new applications of microscopy or where advanced microscopy plays a central role. The journal will publish on the design, methods, application, practice or theory of microscopy and microanalysis, including reports on optical, electron-beam, X-ray microtomography, and scanning-probe systems. It also aims at the regular publication of review papers, short communications, as well as thematic issues on contemporary developments in microscopy and microanalysis. The journal embraces original research in which microscopy has contributed significantly to knowledge in biology, life science, nanoscience and nanotechnology, materials science and engineering.
