Tantalum‐Driven Interfacial Reconstruction Enables Ultra‐Low Contact Resistance in TiAlTa/Au GaN HEMTs

Rare Metals, EarlyView.
ABSTRACT The transformative potential of gallium nitride high electron mobility transistors (GaN HEMTs) in advancing carbon‐neutral power systems remains bottlenecked by contact resistance (Rc) at the metal–semiconductor (M‐S) interface, a critical determinant of switching losses and frequency response.

Interfacial Electronic Interactions in Hierarchical Heterostructure Electrocatalyst for Energy‐Saving Hydrogen Production at Industrial Current Densities

Rare Metals, EarlyView.
ABSTRACT Developing low‐energy‐input electrocatalytic systems for efficient hydrogen production is crucial for advancing sustainable energy technologies. The overall hydrazine splitting (OHzS) has emerged as a promising strategy to reduce the overall energy consumption by replacing the sluggish oxygen evolution reaction.

Ru‐Ag Dual Atom Sites for Methane Detection Enabling Intelligent Thermal Runaway Warning in Lithium‐Ion Batteries

Rare Metals, EarlyView.
ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.

Electronic Modulation of Cu Sites via Iron Incorporation in Cu5FeS4 Bimetallic Sulfide for High‐Efficiency Oxygen Reduction Reaction

Rare Metals, EarlyView.
ABSTRACT The sluggish kinetics of the oxygen reduction reaction (ORR) necessitate developing oxygen electrodes with enhanced electrocatalytic activity for practical zinc–air battery applications. In this study, an iron‐doped copper sulfide electrocatalyst (CuFeNS‐PNC) anchored on metal–organic framework‐derived carbon substrates was designed, featuring

Engineering a Tumor‐Targeted MgH2@Lip/PD‐L1 Nanoplatform for Synergistic Hydrogen Therapy and Immune Activation

Rare Metals, EarlyView.
ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells

Rare Metals, EarlyView.
ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.

Atomic Synergy of Vacancy‐Engineered Layered Double Hydroxide/Heteroatom‐Doped Carbon Quantum Dots for Bifunctional Oxygen Electrocatalysis in Zn–Air Batteries

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Low conductivity and poor oxygen reduction reaction (ORR) catalytic activity limit the bifunctional catalytic performance of layered double hydroxide (LDH) in zinc–air batteries. In this work, an efficient bifunctional electrocatalyst was prepared by loading nitrogen and phosphorus co‐doped carbon quantum dots (NPCQDs) onto a cationic‐vacancy ...
