Molten Zinc Coordination Polymer Glass as a Host for Stable and Processable Optical Dye Composites

EcoEnergy, EarlyView.
Zinc‐based coordination polymer glass is employed to suppress aggregation‐caused quenching (ACQ) and enhance molecular stability, enabling improved luminescence performance in the solid state. The emission color of the hybrid composites can be tuned by varying the incorporated guest molecules, while the glass matrix effectively prevents aggregation and

One‐Pot Spray Pyrolysis Fabrication of Multi‐Phase Lithium Manganese Oxide Microsphere Cathodes for Enhanced Lithium‐Ion Battery Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sr‐LMO microspheres were synthesized by one‐pot spray pyrolysis, forming multi‐phase lithium manganese oxide with Sr‐doped LiMn2O4, Sr2Mn2O5, and Li2MnO3‐like domains. This structure refines particles, suppresses Jahn–Teller distortion, and adds Li+ pathways, delivering superior cycling stability and rate performance over undoped and commercial LMO ...

Synthesis of Carbon Nanotubes From CO2 Enabled by Fe–Mo Bimetallic Catalysts via Effective CO2 Scavenging

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The tandem process involves CO2 methanation and CH4 pyrolysis for CNT synthesis. Unreacted CO2 and H2 from methanation oxidize Fe, suppressing CNT growth on Fe‐only catalysts. Incorporation of Mo into Fe/MgO forms Mo2C, which prevents Fe oxidation under CO2/H2 conditions and thereby enables CNT formation.
