Defect‐Engineered Microwave‐Responsive Ni@C Composites From Waste PET for Catalytic Plastic Upcycling

Advanced Materials, EarlyView.
A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain

Diketopyrrolopyrrole‐Based Cation as a Semiconducting Spacer in Layered Perovskite

Advanced Materials, EarlyView.
Diketopyrrolopyrrole cation incorporated layered perovskites exhibiting extended absorption profiles and enhanced charge carrier mobility with type‐II energy alignment. The improved photoconversion efficiency demonstrates the critical role of incorporating organic semiconductors in optimizing layered perovskite performance.

Ion Concentration and Voltage Imaging With Fluorescent Nanodiamonds

Advanced Materials, EarlyView.
We demonstrate reversible switching between the fluorescent NV0 and the dark NV+ state, in sub‐30 nm FNDs via surface oxidation and hydrogenation, respectively. In an electrochemical cell, we show that the fluorescence from hydrogenated particles enables all‐optical imaging of voltages and ion concentrations at the micrometer scale.

Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes

Advanced Materials, EarlyView.
This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for
