Polycarbazole–NiOOH Interfacial Engineering of BiVO4 Photoanodes for Efficient and Stable Solar Water Splitting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A π‐conjugated carbazole (p‐CBZ) layer is electro‐polymerized on BiVO4 to form a p–n heterojunction that enhances charge separation and suppresses surface recombination, while a NiOOH co‐catalyst accelerates oxygen evolution kinetics. The synergistic BVO/p‐CBZ/NiOOH photoanode delivers a high photocurrent density and long‐term stability for efficient ...

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Regioselective Oxidative Oligomerization of 2‐Tert‐Butylpyrene Toward Structurally Defined Oligomers and Their Application in Organic Light‐Emitting Diodes

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Treatment of 2‐tert‐butylpyrene with Cu2+ afforded structurally well‐defined pyrene oligomers, up to the 13‐mer. Single‐crystal X‐ray diffraction, spectroscopic analyses, and computational studies were conducted to evaluate the properties of the resulting oligopyrenes.

Simulation‐Driven Optimization of a Borosilicate/Al/Al2O3/Graphene Multilayer SPR Sensor for Aqueous Detection of Metal Ions and Their Binary Mixtures

open access: yesElectron, EarlyView.
A cost‐effective surface plasmon resonance sensor using a borosilicate prism, 60 nm aluminum, an optimized 8–10 nm Al2O3 spacer, and graphene oxide achieves up to 338(°)/RIU sensitivity with narrow linewidth, enabling reliable detection and discrimination of Hg(II), Pb(II), Zn(II), and their binary mixtures in water.

Digital Rights Activism in Multilevel Governance

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT Multilevel governance (MLG) without a clear hierarchical structure can create power imbalances among various actors, particularly in settings with overlapping jurisdictions and policy areas. This dynamic is especially pronounced in Internet governance, which faces a complex interplay of domestic laws, state interdependence, and heightened ...
