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

The influence of mechanical activation of chalcopyrite on the selective leaching of copper by sulphuric acid [PDF]

Metalurgija, 2006
In this paper chalcopyrite, CuFeS2, has been selective leached by H2SO4 as leaching agent (170 g/dm3) in procedure of hydrometallurgical production of copper. Mechanical activation of the chalcopyrite resulted in mechanochemical surface oxidation as well

Surface‐Anchored Microgel‐Based Films as Anti‐Icing Coatings

Advanced Materials Interfaces, EarlyView.
The microgel‐based anti‐icing coatings presented in this work reduce ice adhesion by up to 90% on various substrates. This effect can be attributed to the incorporated functional cationic moieties binding a lubricating layer of quasi‐liquid interfacial water.

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

Advanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...
