Lactoferrin Deficiency During Lactation Causes Adult Obesity‐Related Metabolic Disease Through Persistent Adipose Dysfunction Driven by Impaired Adipocyte Development

Advanced Science, EarlyView.
Lactational lactoferrin deficiency exerts lasting effects on epididymal adipose tissue development from lactation into adulthood: it impairs adipocyte hyperplasia and induces pathological hypertrophy, resulting in lower body weight yet exacerbated metabolic dysfunction under a high‐fat diet in adulthood.

Phase‐Resolved Dual Control of Phenol Photodissociation at the Air–Water Interface From Structure‐Resolved Statistics

Advanced Science, EarlyView.
Faster phenol photolysis at the air–water interface arises from two cooperative factors: a more favorable initial microenvironment for solvent‐side electron stabilization, which lowers CI access, and a more labile hydrogen‐bond network, which more readily reorganizes to stabilize the dark‐state intermediate.

Formation of Gallium Monofluoride in the Coordination Sphere of Nickel

Angewandte Chemie, EarlyView.
The elusive gas‐phase species gallium monofluoride forms selectively in the coordination sphere of a nickel(II) centre as a product of C(sp3)–F bond activation, with a weakly coordinating anion as the fluorine source. The herein reported gallium monofluoride ligand acts as a very strong σ‐donor ligand at nickel and serves as a fluorine donor towards ...
