Figure 1: Optical micrographs of point defects. We found that mono-vacancies spend considerably less time as a dislocation pair than do di-vacancies, and the above diffusion mechanism is not important ...

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 ...

System reliability and safety are paramount across industries such as semiconductors, energy, automotive, and steel, where even microscopic cracks or defects within structures can critically affect ...

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 ...

• 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 ...

Quantum blobs: this latest research borrowed from ideas about how diffusion occurs in fluids. (Courtesy: iStock/3quarks) Describing how matter behaves at the quantum-mechanical level is notoriously ...
