What Happens In Material Imperfections at the Atomic Level?
In electronic devices, material imperfections play a key role in determining lifespan as well as in safety considerations. In this video, CHRISTIAN LIEBSCHER puts such defects under the microscope so that we can better understand their atomic structure. Focusing on grain boundaries at which different crystals join together and using transmission electron microscopy, Liebscher explains how this research can bring about improvements in materials science and to the devices that we use in our daily lives.

Max-Planck-Institut für Eisenforschung
Novel alloys for automotive lightweight design and airplane turbines, materials for sustainable energy conversion and storage, and the development of big data and machine learning methods – these are just a few examples of the research areas that are being investigated by the scientists of the Max-Planck-Institut für Eisenforschung. The team of engineers, material scientists, physicists, and chemists develops tailored materials and methods for mobility, energy, infrastructure, and information. To this end, the researchers study complex materials with atomic precision under real environmental conditions.
