Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 272-283, January 2023., 2023 Abstract The chemical footprint (ChF), which combines life cycle assessment (LCA) and quantitative risk assessment principles, shows promise for exploring localized toxicity impacts of manufacturing processes, which is not achievable with LCA alone. An updated ChF method was applied to the global annual production of a hard disk drive (HDD) rare‐earth ...

Journal of Computational Chemistry, Volume 44, Issue 3, Page 190-198, January 30, 2023., 2023 Actinoid tetroxide molecules AnO4 (An = Ac – Cm) are investigated by the multi‐configurational DMRG approach. The Natural Orbital Plots show the number of local An‐5f electrons, and thereby the oxidation states, at one glance. The 5f orbital's increasing energetic stability and spatial immersion in the actinide cores along the series of actinoids ...
