Covalently Bonded S‐Scheme Polymer Heterojunction for Highly Efficient Solar Hydrogen Evolution

EcoEnergy, EarlyView.
A covalently integrated all‐organic S‐scheme heterojunction (B‐CN2@Py‐CN) establishes atomic‐level charge transport channels and a strong built‐in electric field, enabling exceptional charge separation efficiency. This molecularly engineered photocatalyst achieves a cocatalyst‐free hydrogen evolution rate of 27.9 mmol g−1 h−1 under visible light ...

Machine Learning–Enhanced Fluorescence Cryptography with NADH‐Responsive Polymer Dots

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a smart anticounterfeiting system using semiconducting polymer dots (Pdots) that exhibit tunable fluorescence responses to NADH. By integrating these dynamic optical signals with machine learning–based decoding, the work establishes a secure and intelligent encryption platform, showing a novel strategy that links chemical sensing ...

Synergistic Microstructure and Dielectric Engineering of Recyclable Single‐Electrode Triboelectric Nanogenerators for Sustainable Smart Homes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A recyclable triboelectric nanogenerator integrating a pseudo‐honeycomb microstructure with liquid metal doping achieves 120% higher output (122 mW m−2) and >90% retention over seven cycles, enabling self‐powered smart home functions. The performance of single‐electrode triboelectric nanogenerators (SE‐TENGs) is governed by the effective contact area ...

State‐Level Politics in Forest Governance: The Role of the Narrative‐Policy Nexus in the Brazilian Amazon

Environmental Policy and Governance, EarlyView.
ABSTRACT Deforestation and its social impacts are an enduring challenge in agrarian frontiers, especially in the tropics. Fueled by global demand for commodities, this process is mediated by ideas, concepts, meanings, and policies that uphold socioenvironmental degradation. A key and understudied—arena in which this mediation occurs is the sub‐national

“Passive” Scalecraft as a State Strategy in Post‐Authoritarian Environmental Governance: A Case From South Korea

Environmental Policy and Governance, EarlyView.
ABSTRACT This study employs a scalar politics framework to unpack how participatory rhetoric operates statecraft in a post‐authoritarian context, thereby illuminating hybrid‐regime behavior along a continuum of environmental governance. An examination of the environmental governance of an ecotourism project in South Korea is performed using ...
