Colloid‐Mediated Surface Reconstruction Through High‐Valence Element Integration Enables Stabilized Oxygen Redox and Fast Interfacial Kinetics in Li‐Rich Cathodes

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lithium‐rich manganese‐based cathodes (LRM) deliver high discharge capacities beyond 250 mAh g−1, but their practical deployment is restricted by irreversible oxygen redox, structural reconstruction, sluggish kinetics and unstable cathode‐electrolyte interfaces (CEI). Here, we develop a colloid‐assisted anchoring‐diffusion engineering strategy

SET circuits design based on theory of transmission voltage-switches(基于传输电压开关理论的单栅极SET电路设计)

Zhejiang Daxue xuebao. Lixue ban, 2012
在分析了单电子晶体管(SET)的I-V特性后，通过对SET背景电荷的设置，使之具有类似PMOS或NMOS的电学特性；同时将传输电压开关理论引入到SET的电路设计中，并用单栅极SET实现了该理论的基本运算电路.随后以异或门和一位比较器为例，利用这些基本运算电路，进行了基于SET的开关级电路设计.最后，利用Pspice软件验证了所设计的电路逻辑功能正确，设计方法可行；电路的输入输出高低电平一致，具有良好的电压兼容性，易于级联.仿真结果表明，与基于互补结构设计的SET电路相比 ...

Lignin‐Derived Carbon Quantum Dots as Hole‐Trapping Promoters in LCDs/Bi‐MOF/ZIS With S‐Scheme Heterojunction for Efficient Photocatalytic Hydrogen Peroxide Production in Pure Water

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Photocatalytic hydrogen peroxide (H2O2) production from water and oxygen driven by solar energy represents a highly promising green and sustainable strategy. Herein, lignin‐derived carbon quantum dots (LCDs) were strategically introduced at the heterojunction between a Bi‐based metal organic framework (Bi‐MOF) and ZnIn2S4 (ZIS).

Electron–Hole Dual Cocatalyst Promoted ZnIn2S4 for Photocatalytic H2 Evolution Coupled With Benzyl Alcohol Oxidation

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The central challenge in photocatalysis is to direct photogenerated electrons and holes toward the simultaneous and efficient production of hydrogen and value‐added chemicals. To address the pronounced charge recombination and sluggish surface kinetics of ZnIn2S4 nanoflowers, we construct a ternary photocatalyst synergistically decorated with ...

Biomass‐Derived Laser‐Induced Graphene: From Precursor Chemistry to Device Integration

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Laser direct writing provides a mask‐free route for converting suitable carbon‐containing precursors into patterned, porous, and conductive laser‐induced graphene (LIG) networks. Although LIG was initially demonstrated mainly using aromatic synthetic polymers, such as polyimide, biomass precursors introduce renewable feedstocks with highly ...

Balancing d‐π/d‐π* Interactions: Valence‐Engineered Pd/TiO2 for Photocatalytic Acetylene Semi‐Hydrogenation

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Photocatalytic acetylene (C2H2) semihydrogenation is a green route for ethylene (C2H4) production, yet the activity–selectivity trade‐off caused by imbalanced adsorption/activation of reactants and products remains a core challenge. Herein, we realize precise regulation of Pd oxidation states (Pd0, Pdδ+, and Pd2+) on anatase TiO2 nanocubes via

Advanced Electrospun Nanofiber Epidermal Electronics for Electrophysiological Monitoring: From Conformal Interfaces to Multimodal Closed‐Loop Systems

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Epidermal bioelectronics is a transformative technology for continuous health monitoring and human‐computer interaction. However, the mechanical and physiological mismatch at the skin–device interface limits its long‐term application. Electrospun nanofiber membranes (ENMs), with their unique three‐dimensional hierarchical porous network and ...

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

Mesoporous Hexametallic High‐Entropy Alloy Nanotubes With Multicomponent Electronic Modulation for Efficient Bifunctional Catalysis

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Platinum‐based electrocatalysts are fundamentally constrained by strong oxygen binding, which restricts the oxygen reduction reaction (ORR) kinetics, and by severe CO poisoning, which hinders the methanol oxidation reaction (MOR). To address these limitations, we synthesized PdPtRuIrRhNi high‐entropy alloy (HEA) mesoporous nanotubes that ...
