Interfacial Proton‐Relay Microenvironment Enables Self‐Driven Singlet Oxygen Generation under Neutral Conditions

Advanced Science, EarlyView.
An interfacial proton‐relay microenvironment at MoS2‐CuCl heterostructures enables selective O2 activation to 1O2 under neutral conditions. Electron‐deficient sulfur sites mediate proton transfer to Cu‐bound O2, accelerating *OOH hydrogenation while suppressing O─O bond cleavage, achieving stable, efficient pollutant removal.

Climatic drivers prevail in montane and lowland Odonata latitudinal diversity gradients, but human modification erodes lowland patterns

Ecography, EarlyView.
Latitudinal diversity gradients (LDGs) arise from the interplay of historical, ecological, and evolutionary processes, yet these drivers may differ across landforms. Mountains, with steep elevational and climatic gradients, often sustain distinct diversity dynamics compared with adjacent lowlands, where vertical climatic gradients are weak and human ...
