A Molten Salt Strategy to Convert Bulk Nb2O5 Into 2D Nonlayered Niobium Nitride Nanosheets for Superior Pseudocapacitive Storage

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Two‐dimensional (2D) nonlayered niobium nitrides have attracted considerable interest for electrochemical energy storage. However, the synthesis of these materials is hampered by their nonlayered crystal structures, which are characterized by strong three‐dimensional chemical bonding.

F‐Mediated Precise Control Over Amorphous/Crystalline Fe/Ni‐Based Phosphides Heterostructure for Efficient Oxygen Evolution Reaction

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Transition metal‐based amorphous/crystalline (a/c) heterostructured catalysts have garnered significant attention due to their exceptional activity, stability, and cost‐effectiveness. However, the precise synergistic regulation of interfacial composition and phase states remains challenging.

Breaking Hardness–Toughness Trade‐Off in Novel (V, Nb)C Carbides via Nanoscale Phase Separation and Local‐Chemical‐Order Dislocation Network

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Transition metal carbides demonstrate exceptional mechanical properties but confront a critical hardness–toughness trade‐off. Spinodal decomposition‐mediated phase separation is an effective approach to enhance mechanical properties in carbide ceramics through high‐temperature treatment.

Hollow Porous Nitrogen‐Doped Carbon‐Confined FeP/Fe2P Nanoparticle‐Armored Catalyst for Efficient Oxygen Reduction Reaction in Aqueous/Flexible Zinc‐Air Batteries

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT The design of nanoparticles confined in hollow N‐doped carbon structures is crucial for improving the oxygen reduction reaction (ORR) kinetics, yet achieving this remains a significant challenge. In this work, hollow porous nitrogen‐doped carbon encapsulated FeP/Fe2P (H‐FeP/Fe2P) were successfully constructed via a templating method combined ...

Primary saltmarsh succession on a tropical coral island in the South China Sea: Human influences initiate and accelerate the process of succession

open access: yesEcological Solutions and Evidence, Volume 6, Issue 2, April–June 2025.
Pioneer grass species rapidly colonized the site within 1 year following land reclamation, with a grass‐to‐shrub transition concurrently with dike construction, indicating a clear trajectory of species establishment and development in a newly formed saltmarsh.

The Effect of Loosening Means‐Testing Requirements on Income Assistance Flows in British Columbia Canada

open access: yesPoverty &Public Policy, Volume 16, Issue 4, Page 309-322, December 2024.
ABSTRACT In Canada, eligibility for provincial income assistance requires applicants and recipients to pass a means test—they must have income and assets below a specified level. The “good policy” argument argues that strict means tests ensure those with sufficient income or assets cannot access nor continue on income assistance, keeping caseloads low.
