在 STEM 中获取的最常见信号是明场 (BF)、环形暗场 (ADF) 和高角度环形暗场 (HAADF) 图像。该技术通常与能量色散 X 射线光谱 (EDS) 和电子能量损失光谱 (EELS) 结合使用，以提供元素成分和电子结构的相关光谱图。 为 STEM 制备的材料需要具有电子透明性，这意味着它们 ...

How Healthy Stem Cells Turn Into Oral Cancer Feb. 4, 2025 — Researchers have identified the molecular and cellular mechanisms that transform healthy stem cells into oral cancer at the earliest ...

Following purification, the material transforms into pure gold, enabling distinct plasmonic responses, as illustrated by the colored STEM-EELS maps. The objective of this study was to achieve full ...

To investigate the prevalence and consumption of endangered eels, a research team examined 327 individual eel products purchased across 86 retailers throughout Singapore. The team discovered ...

透射电子显微镜 (TEM) 是一种用于观察物质中最小结构的分析技术。与依赖可见光谱中的光的光学显微镜不同，TEM 可以通过将纳米结构放大 5000 万倍来揭示原子尺度的惊人细节。这是因为电子在通过强电磁场加速时，其波长可以比可见光短得多（大约小 ...
