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

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study develops a scalable and universal liquid‐phase synthesis method of halide solid electrolytes using nitrogen‐containing solvents. The Li2YCl5−yBry (y = 0, 2, and 5) solid electrolytes synthesized via pyridine solvent exhibit an ionic conductivity over 1 × 10−4 S cm−1 at 25 °C.

On the synthesis of 3-cyano-6-hydroxy-4-methyl-2-pyridone at room temperature
Zaštita Materijala, 2019 Milling of cyanoacetamide and acetoacetic ester as reactants, in the presence of KOH as the catalyst and ethanol as a viscous control agent (VCA) was performed in a planetary ball mill with the goal of investigating the effect of mechanochemical ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A sustainable upcycling strategy transforms tungsten carbide–cobalt (WC–Co) soft scrap into high‐performance cathode materials. Recycled Co with trace nickel (Ni) is resynthesized into stabilized LiCoO2 with superior high‐voltage durability, while the recovered tungsten is further utilized as tungsten trioxide to enhance Ni‐rich cathode interfaces ...
