Abstract
Environmental atom probe tomography and multi-scale modeling reveal electric field effects in iron oxidation, as demonstrated by Sten V. Lambeets, Jean-Sabin McEwen et al. in their Research Article (e202423434). The inhomogeneous field on an iron tip (grey/black spheres) creates an uneven oxygen distribution. The field gradient, shown as an intensity grid, is strongest near the tip. Surface composition is probed upon exposure to oxygen (red spheres) by collecting emitted iron oxide cations, which are then compared to field-based oxidation calculations.
Sten V. Lambeets、Jean-Sabin McEwen等人在他们的研究文章（e202423434）中证实，环境原子探针断层扫描和多尺度建模揭示了电场对铁氧化的影响。铁尖（灰球/黑球）上的不均匀场造成了不均匀的氧分布。以强度网格表示的场梯度在尖端附近最强。在暴露于氧气（红色球体）时，通过收集发射的氧化铁阳离子来探测表面成分，然后将其与基于场的氧化计算进行比较。
