Trigonal Phosphine Umpolung: Electrophilicity Driven by a Redox‐Active Boron Cluster

Chemistry – A European Journal, EarlyView.
Coupling of a phosphine to a redox‐active cluster enables polarity reversal, or umpolung, at phosphorus. Phosphines are classically known for their nucleophilicity, and while electrophilic reactivity has been observed in geometrically constrained, non‐trigonal systems, similar behavior in ordinary trigonal phosphines is rare.

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

EcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

Hot spots or hot moments? Contextualizing the spatio‐temporal scale of research on animal inputs

Ecography, EarlyView.
Mammals play important roles in redistributing elements across ecosystems, concentrating biogeochemical inputs across both space and time. However, research on zoogeochemical inputs is often constrained by logistical considerations, potentially limiting our knowledge of mammals' impacts on biogeochemical patterns and processes.
