Nuclear and Renewable Energy Transitions for Global Sustainability: Exploring the Interactions of Tourism Development and Economic Drivers

ABSTRACT In light of exacerbating climate change issues, recent environmental policy reforms have attempted to balance economic growth and environmental conservation to foster a sustainable development transition. To further debate the scope of decarbonization policies, this stud...

FH-YOLO: a cross-stage stabilized framework for underwater benthic object detection

Underwater object detection is challenged by light attenuation, scattering, and severe appearance degradation, which introduce instability across different stages of the detection pipeline. To address this issue, we propose FH-YOLO, a cross-stage stabilized framework designed to...

Copper binding heterogeneity of pH-fractionated soil dissolved organic matter (DOM) revealed by multi-spectroscopy and two-dimensional correlation analysis

Soil dissolved organic matter (DOM) plays a pivotal role in governing the environmental behavior and fate of metal ions. The inherent heterogeneity of DOM, however, leads to complex and poorly understood interactions with heavy metals. In this study, soil DOM was fractionated int...

Regulating H‐Aggregation via a Thiazole‐Modified Acceptor‐Based Packing Reshaper Toward Highly Efficient and Stable Organic Solar Cells

ABSTRACT Organic solar cells (OSCs) based on non‐fullerene acceptors have achieved power conversion efficiencies (PCEs) exceeding 20%. However, their long‐term stability remains limited by uncontrolled molecular aggregation and morphological degradation in bulk heterojunction (BH...

Ordered J‐Aggregation Directed by Inner Alkyl Chains Enables Additive‐ and Annealing‐Free Organic Solar Cells With 20.73% Efficiency

ABSTRACT Molecular aggregation behavior of non‐fullerene acceptors (NFAs) plays a pivotal role in the photovoltaic performance of organic solar cells (OSCs). In Y‐series NFAs, excessive H‐like core contacts may increase packing disorder, while terminal group‐mediated J‐like inter...

A Stage‐Coupled View of Interfacial Reconstruction in Anode‐Free Sodium Metal Batteries

ABSTRACT Anode‐free sodium metal batteries (AFSMBs) remove the excess metal anode and increase projected cell‐level energy density, but they place reversibility on a transient negative‐electrode interface. In each cycle, Na is deposited on a foreign current collector and removed...

HydrochloricAcid-Assisted Synthesis of Red EmissiveHybrid Mn2+ Halides for Wide Gamut Displays

Abstract Lead-free red emissive hybrid Mn2+-based metal halides have emerged as promising phosphors for lighting and display applications owing to their environmental friendliness and d–d transition. However, simultaneously enhancing emission efficiency and narrowing the red-emis...
