Small, Volume 21, Issue 2, January 15, 2025.State‐of‐the‐art quantum chemistry methods are used to characterize the spin switching of strapped Ni porphyrin molecules deposited on Ag(111) surface. The LS and HS states are related by a vertical shift of the pyridine ligand, that modifies the Ni coordination number and promotes the spin transition. The voltage‐dependent spin switching is related to

Land Use Change Consistently Reduces α‐ But Not β‐ and γ‐Diversity of Bees
Global Change Biology, Volume 31, Issue 1, January 2025.We analyzed a global dataset of 3117 bee assemblages across 157 studies to assess how bee diversity varies among natural, agricultural, and urban habitats. We measured diversity using both the number of bee taxa (taxonomic diversity) and their evolutionary relationships (phylogenetic diversity).
