Discovery of Sustainable Energy Materials Via the Machine‐Learned Material Space

open access: yesSmall, EarlyView.
State‐of‐the‐art machine learning models used in materials science are shown to construct meaningful internal representations, which can be interpreted as a map of the material space from the viewpoint of the network. It shows how this map can be used to find alternative, e.g., more sustainable materials for important optical materials, such as ...

Hydroxide Mobility in Aqueous Systems: Combining Ab Initio Accuracy with Millisecond Timescales

open access: yesSmall, EarlyView.
A multiscale simulation strategy for hydroxide transport in aqueous potassium hydroxide is presented, integrating ab initio molecular dynamics with force field and Monte Carlo methods. The approach links femtosecond‐scale hydrogen‐bond dynamics to millisecond‐scale diffusion while maintaining near‐ab initio accuracy.
