Superstructure Reconstruction Stabilizes Anionic Redox in Cobalt‐Free Lithium‐Rich Layered Cathodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Superstructure reconstruction through Ni3+‐induced Ni/Mn exchange stabilizes the anionic redox in cobalt‐free lithium‐rich cathodes. This strategy mitigates oxygen loss and transition metal migration, yielding high capacity (231 mAh g−1) and durable cycling (84% over 500 cycles) with suppressed voltage decay. Structural degradation in Li‐rich manganese‐

Intrahour Direct Normal Irradiance Forecasting Based on Sky Image Processing and Time-Series Analysis

SolarPACES Conference Proceedings
The present paper exhibits a hybrid model for intrahour forecasting of direct normal irradiance (DNI). It combines a knowledge-based model, which is used for clear-sky DNI forecasting from DNI measurements, with a machine-learning-based model, that ...

Towards Transformative Climate Governance: Capacities and Constraints for Local Government in Aotearoa New Zealand

Environmental Policy and Governance, EarlyView.
ABSTRACT An emerging consensus calls for transformative climate governance. However, what instigates and sustains transformative pathways remains unclear. This study characterises the existence, quality and structural underpinnings of transformative governance capacities in local government climate change response in Aotearoa New Zealand, applying a ...

Bridging Policy Gaps in Transition Times: How Local Actors Navigate Low Policy Coherence for Advancing a Circular Built Environment

Environmental Policy and Governance, EarlyView.
ABSTRACT The construction sector is a major contributor to the climate crisis, accounting for over one‐third of global energy‐related CO2 emissions. In response, the European Commission identified the circular economy as a means of achieving green growth and prioritized the construction sector in its Circular Economy Action Plan.

How Multiple Streams Influence Agenda‐Setting for Water Reuse in Swiss Substates

Environmental Policy and Governance, EarlyView.
ABSTRACT As climate change creates significant challenges for both the environment and society, potential mitigation and adaptation solutions are widely discussed. Yet, neither challenges nor their potential solutions automatically reach the political agenda or lead to a policy decision.

Overcoming Cell Fixture Challenges in High‐Pressure Operation of Solid‐State Batteries

Energy Science &Engineering, EarlyView.
Accurate application of high uniaxial pressure remains a limiting factor in large‐format solid‐state battery testing. A spring‐loaded fixture employing deflection‐based pressurization enables precise, homogeneous, and reproducible pressure application without expensive in‐fixture sensors, providing a robust framework for systematic investigation of ...
