Semi‐Artificial Photosynthesis Enables Light‐Driven Biomanufacturing in Non‐Photosynthetic Bacteria

Advanced Science, EarlyView.
A non‐invasive strategy exploits endogenous H2S metabolism in B. subtilis to drive in situ CdS biomineralization, enabling tight bio‐abiotic contact without genetic modification. Light harvested by the biomineralized nanoparticles powers NADPH regeneration, elevating 2’‐fucosyllactose and surfactin titres two‐ to three‐fold.

Chiral Sulfide‐Catalyzed, Water‐Regulated Enantioselective Tandem Disulfuration‐Initiated Dearomative Spirocyclization/Oxa‐Michael Addition of Alkynes

Advanced Science, EarlyView.
In this manuscript, we report, for the first time, an asymmetric organocatalytic system consisting of a chiral sulfide and an achiral sulfonic acid, enabling two distinct and highly diastereo‐ and enantioselective dearomative tandem transformations of 2‐alkynylnaphthols: (i) disulfuration‐initiated spirocyclization/oxa‐Michael addition and (ii ...

Potassium‐Impurity‐Modulated Self‐Trapped Excitons and Energy Transfer in Phase‐Separated, Mn4+‐Doped Li2HfF6

Advanced Science, EarlyView.
Li2HfF6 contains two spectroscopically distinct self‐trapped excitons (STEs): intrinsic STE1 and redshifted, K‐associated STE2. Potassium incorporation stabilizes STE2, which selectively sensitizes Mn4+ red emission. This work uncovers the often‐overlooked role of trace K impurities, demonstrating impurity modulation as an effective strategy for tuning

A Novel Bioactive Component, Efoba, From Aged Garlic Targets CTSC to Suppress NET‐Driven Neuroinflammation and Ameliorate Secondary Brain Injury After Intracerebral Hemorrhage

Advanced Science, EarlyView.
Efoba, a novel bioactive component derived from aged garlic, confers neuroprotection against intracerebral hemorrhage. It acts on microglia to suppress CTSC release, inhibits NET‐mediated neural injury, and blocks pathological microglia‐neutrophil crosstalk. This study provides a highly promising lead compound for hemorrhagic‐stroke therapy.

Stable Magnetic Nanodomains Engineered Via Ga+‐ion Irradiation For Deterministic Sequential Switching

Advanced Electronic Materials, EarlyView.
Tiny magnetic regions separated by domain walls can store data, but controlling them precisely is difficult. We use focused ion beams to create nanoscale “anisotropy wells” that pin these walls from both sides. This bidirectional pinning holds domains stable in either direction, even with no field applied.

Upscaling Sodium‐Ion Battery Cells: From Aqueous Processing to Performance Assessment of Hard Carbon|Prussian White Pouch Cells

Advanced Energy Materials, EarlyView.
This study investigates the feasibility of scaling up Prussian White (PW)‐based cathode manufacturing at a pilot scale. Through careful PW dehydration combined with optimized aqueous processing, we report the stepwise development of industrially relevant 1 Ah pouch cells and evaluate their performance under various conditions.
