Revealing the Roles of Electrolyte Concentration on Transition Metal Dissolution and Reaction Pathway of Anion Adsorption Pseudocapacitance

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...

Dual‐Site Electronic Modulation in Mn/Fe‐Doped Ni0.85Se for High‐Efficiency Urea Oxidation at Industrial Current Density

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Rationally designing an electrocatalyst to achieve stable and efficient urea oxidation reaction (UOR) is crucial but still challenging, especially for ampere‐level application. Herein, Mn and Fe dual‐doped Ni0.85Se (Mn/Fe–Ni0.85Se) catalyst is synthesized via a facile and scalable electrodeposition and followed by selenization.

Pinus armandii ectomycorrhizas mobilize aluminium‐bound phosphorus via carboxylates along a subtropical altitudinal gradient

open access: yesJournal of Ecology, Volume 114, Issue 8, August 2026.
Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

Defect‐Regulated Electronic and Lattice Evolution in Na4VMn(PO4)3 Toward High‐Performance Sodium Storage

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT NASICON‐type Na4VMn(PO4)3 (NVMP) is a promising high‐capacity cathode for sodium‐ion batteries, yet its practical deployment is hindered by Mn3+‐driven lattice distortion, persistent oxygen vacancy defects, and sluggish Na+ transport, collectively resulting in accelerated performance degradation.
