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

Toluene-styrene secondary acclimation improved the styrene removal ability of biotrickling filter

Chemical Speciation & Bioavailability, 2017
In this work, ceramic pellets were used as packing material to establish a biotrickling filter (BTF) with acclimated sludge being inoculated on the surface of the packing to purify waste gas containing styrene.

Reaction-controlled phase transfer catalysis for styrene epoxidation to styrene oxide with aqueous hydrogen peroxide

, 2005
The epoxidation of styrene catalyzed by a reaction-controlled phase transfer catalyst [(C18H37(30%)+C16H33(70%))N(CH3)(3))(3)](3)-[PW4O16] with H2O2 in a biphasic medium was investigated. Under certain conditions, the selectivity for styrene oxide was 95%

Stress Transfer Within Microphase‐Separated Structures: A Post‐Synthetic Strategy to Impart Mechanoresponsiveness to Block Copolymer Materials

Advanced Materials, EarlyView.
A domain‐engineered post‐functionalization strategy is presented to impart mechanochromism to styrene–butadiene–styrene (SBS) block copolymers by simple blending with a tetraarylsuccinonitrile (TASN) mechanophore‐containing polystyrene (PS‐TASN‐PS). The resulting materials exhibit reversible fluorescence under tensile deformation while preserving, or ...

How “Green” is Your Functional Material? Assessing Environmental Impacts of Multi‐Step Synthetic Protocols in Material Sciences at Various Technology Levels

Advanced Materials, EarlyView.
Environmental Synthesis Radar (ESR) evaluates the environmental impact of (early‐stage) multi‐step chemical syntheses, providing a holistic view by using 18 midpoint impact categories. Unlike conventional life‐cycle assessment (LCA) approaches, ESR reveals three complementary metrics: overall impact Vtotal, environmental hotspots VEF, and critical ...
