Motion of defects (dislocation loops) in tungsten at low temperature. Courtesy: CEA “Massively heavy” atoms can move quantum mechanically within a crystalline material at cryogenic temperatures. This ...

This news release is available in German. Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many ...

Notably, signals measured by physical sensors--such as ultrasonic or electromagnetic waves--are often distorted by factors including geometry, material properties, and complex real-world conditions, ...

本文创新性地提出一种布局到缺陷（layout-to-defect）生成方法，通过利用预训练布局条件扩散模型（如Stable Diffusion）的生成先验，在有限缺陷数据下实现高精度类别-区域可控的工业缺陷合成。该方法突破传统生成模型需大量训练数据的限制，生成的图像可直接 ...

Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging ...

• The underlying migration mechanism of Mg 2+ in cathode materials and roles of defects in Mg 2+ migration in cathode materials were studied. • Applications of defect engineering to Mg 2+ migration in ...
