How batteries grow old

Ohio State University researchers conducted experiments to test commercially available Li-ion batteries thousands of times, finding irreversible changes at the nanoscale that lead to battery loss of charge. The study suggests that coarsening of electrode materials may be responsible for this loss.

3-D X-ray images of nanoparticles

The new X-ray microscope resolves details down to 17 nanometers, allowing for the study of quantum dots and other nanomaterials in three dimensions. This technique opens up comprehensive imaging capabilities for various samples, including porous materials, semiconductors, and biomaterials.

Snapshots at the atomic border

Researchers use high-resolution transmission electron microscope to study interactions at solid-liquid interfaces, observing density fluctuations and atom ordering in liquid aluminium. The findings suggest that crystals can induce the ordering of atoms in liquids, even in metal-ceramic systems at high temperatures.
