mGluR5 in ECCCK to BLA Circuit Modulates Depressive‐Like Phenotypes through CCK Signaling

Advanced Science, EarlyView.
Dysregulation of mGluR5 and CCK signaling contributes to major depressive disorder, yet circuit‐level mechanisms remain unclear. Here, the ECCCK→BLA pathway is identified as a critical regulator of affective behavior. mGluR5 modulates synaptic function and CCK signaling within this circuit, controlling stress susceptibility and depressive‐like states ...

Enhanced Energy Transfer from a Metal–Organic Framework to a Highly Confined Organic Phosphorescent Dye

Advanced Science, EarlyView.
A phosphorescent dye was designed to fit in a hand‐to‐glove fashion into the 1D‐pore channels of MIL‐68(In). We synthesized MIL‐68(In) as powder and thin films, loaded the dye into the pores with controlled packing, and found that the phosphorescence and quantum yield are enhanced.

Stabilizing Atomically Dispersed Au With Adjacent Pt for Spatially Precise Molecule Recognition

Advanced Science, EarlyView.
A strategy to stabilize atomically dispersed Au catalysts by introducing Pt atoms into CeO2 supports is presented. Pt incorporation prevents Au aggregation, enhances Au‐O orbital coupling, and enables precise recognition of multi‐functionalized molecules, improving catalytic performance and the structural stability of Au‐based catalysts in ...
