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 ...

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, ...

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 ...

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 ...

AI can find hidden cracks inside machines and buildings in real time, helping prevent accidents and keep industries safe.

• 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 ...
