Interfacial Charge‐Transfer Enhancement via High‐Entropy Alloy Regulated MXene Heterostructures for Asymmetric Supercapacitor Applications

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel core‐shell HEA@MXene composite was synthesized to enhance supercapacitor electrochemistry. DFT simulations reveal the role of HEA doping in regulating the MXene interface. The HEA@MXene composite exhibits a high specific capacitance of 872 F g−1 at 1 A g−1 with remarkable stability in 1 M KOH.

Orbital Coupling and Electron Delocalization Engineered at Fe/V Heterointerfaces for Enhanced Cathode Performance in Sodium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In the NFPF–NVPF heterostructure, the interfacial FeV 3d‐orbital coupling drives the upshifting of the d‐orbital and facilitates electron delocalization. This dual‐effect mechanism significantly expands the spatial distribution of electrons and narrows the bandgap, thereby constructing synergistic electron‐ion transport channels to achieve excellent ...

Water Governance Under International Pressure: Policy Narratives, Food Security, Scarcity, and the Politics of Survival in Iran

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Water governance is increasingly influenced by a paradox at the nexus of environmental scarcity and food security. Escalating water scarcity crises coincide with geopolitical disruptions that have exposed the fragility of global food supply chains, prompting states to expand domestic food production at the expense of water conservation ...

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

open access: yesGeological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.
