Rare Metals, Volume 45, Issue 3, March 2026.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, Volume 45, Issue 3, March 2026.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 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Photocatalytic hydrogen production from water splitting is a promising strategy for sustainable and clean energy generation. However, the design of low‐cost, highly active photocatalysts remains a critical challenge. In this study, covalent organic frameworks (COFs) were loaded onto the surface of Cd0.9Cu0.1S to fabricate COF/Cd0.9Cu0.1S ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional electrocatalysts is a key challenge for the industrialization of hydrogen production by water electrolysis. In this work, Co‐doped NiS/Ni3S2 heterostructured nanowire arrays (Co–NiS/Ni3S2 NA) were successfully constructed by precisely modulating the phase‐selective behavior of nickel ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...

People and Nature, Volume 8, Issue 2, Page 270-282, February 2026.Abstract Chinese consumer demand for ivory threatens vulnerable African elephant populations, despite long‐standing efforts to combat the illegal wildlife trade. Behavioural science approaches have been proposed to address these systemic behaviours. However, their robust use remains uncommon in demand management interventions.

Multi‐Functional S‐HA/ASTA NPs Coating on Biodegradable ZE21B Alloy for Cerebrovascular Applications
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Magnesium (Mg) and its alloys have attracted extensive attention of researchers in the field of cerebrovascular implants due to their good mechanical properties and biosafety. However, rapid degradation and delayed endothelialization pose challenges. To address these issues, this study introduces a multifunctional composite coating.

Gaoya dianqi, 2007 将由电源滤波器、压敏电阻、瞬态电压抑制器（TVS）组成的串级浪涌抑制网络应用于智能电器监控单元电源端口,通过试验观察到该网络的残压水平过高,对后级电路存在着潜在的危险,采用波过程理论对这一现象进行分析,发现开关电源阻抗变化会影响到串级浪涌抑制网络的配合。对抑制网络的结构进行了改进,通过试验可以证明改进后的抑制网络能够明显提高对浪涌过电压的抑制效果。
