Cobalt‐Free Single‐Crystal Cathodes for Next‐Generation Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cobalt‐free single‐crystal cathodes enhance lithium‐ion battery stability by mitigating fracture, degradation, and phase transitions. This review highlights Ni‐rich layered, Li‐Mn‐rich, spinel, and olivine frameworks, synthesis strategies enabling morphology and defect control, and structural tuning via doping and coatings, offering pathways toward ...

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

From Contingency Management to Transformative Climate Risk Adaptation? Analysis of Private Sector Agency in Navigating Complex Climate Risk Realities

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The growing complexity and severity of cross‐border climate risks characterised by non‐linear impact chains and deep uncertainty questions the capacity of environmental governance to tackle these problems effectively and in a just manner. To increase the efficiency of climate action, the private sector has been called upon to leverage market ...

Empathy, Perceived Injustice and Solidarity‐Based Action: Observer Responses to Civilian Suffering in Military Conflicts

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT As global conflicts intensify, observers without direct conflict experience are increasingly exposed to war‐related suffering through media coverage, yet little is known about how such exposure shapes emotional and behavioural responses or how support for different affected civilian groups is distributed.

EU Policy‐Making in the Digital Age: Major Trends and Insights From Public Policy Research

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT Has digitalization changed policy‐making dynamics at the European Union (EU) level? To investigate this issue, this article presents a scoping review of the literature on EU digital policy‐making. While much scholarship adopts a ‘Governance’ approach, two conceptually rich strands emerge: critical approaches, and digital sovereignty.

Robust Control Using a Matrix Converter to Enhance Wind Turbine Systems

open access: yesEnergy Science &Engineering, EarlyView.
This study uses a more efficient and effective solution to improve the operational performance of a wind turbine‐based power system. This system uses a doubly fed induction generator and relies on a matrix converter and fractional‐order proportional–integral controller.

Intraday Functional PCA Forecasting of Cryptocurrency Returns

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT We study the functional PCA (FPCA) forecasting method in application to functions of intraday returns on Bitcoin. We show that improved interval forecasts of future return functions are obtained when the conditional heteroscedasticity of return functions is taken into account.
