Beyond Water: Deep Eutectic Solvents Enable Dye‐Sensitised Photocatalytic Hydrogen Production

open access: yesChemSusChem, Volume 19, Issue 9, 14 May 2026.
Dye‐sensitised photocatalytic H2 evolution is demonstrated for the first time in deep eutectic solvents (DESs). Carbazole‐based dyes with different hydrophobicity sensitise Pt@TiO2, revealing that heterogeneous dye–DES combinations maximise activity. Interfacial solvation and charge transfer govern enhanced hydrogen production under visible light. This

Sustainable and Direct Recovery of Lithium‐Ion Battery Cathodes From Production Scraps

open access: yesChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Lithium‐ion batteries (LIBs) represent the dominant energy storage technology, and as their demand continues to rise, the efficient recycling and recovery of critical elements from their cathodes become increasingly important. Direct recovery of active electrode materials from spent LIBs or electrode manufacturing scraps offers an effective strategy to

Ion Beam Sputtering Deposition to Prepare Pt/ZrO2 Active Layer for Hydrogen Evolution and Oxidation Reaction

open access: yesChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Pt@ZrO2 thin films are fabricated by ion beam sputtering as compact, binder‐free electrodes with low Pt loading (0.0475 mg·cm−2). The intimate mixing between the noble metal and the ceramic support enhances intrinsic catalytic activity toward alkaline hydrogen evolution, allowing a significant reduction in precious metal loading while maintaining ...

Capturing State‐of‐Charge‐Dependent Efficiency in Battery Energy Storage Systems: A Bernoulli Model Approach

open access: yesBattery Energy, Volume 5, Issue 3, May 2026.
Conventional battery energy storage system models assume constant efficiencies, overlooking key physical limitations. This work introduces an analytical model with realistic state‐of‐charge (SOC)‐dependent efficiencies and charge acceptance, predicting that system operation concentrates in intermediate SOC ranges—a critical, overlooked behaviour ...

Contesting Regulatory Capacity: Exploring Doctrines in the Regulatory State

open access: yesPublic Administration and Development, Volume 46, Issue 2, Page 197-207, May 2026.
ABSTRACT The contemporary literature on regulation and development has emphasised the importance of low discretion devices for achieving desired policy objectives. At the same time, there has been a growing recognition that state capacity in general, and regulatory capacity more specifically, are essential for achieving development goals in a world of ...
