Machine Learning‐Driven Discovery and Experimental Validation of Effective Precursor Additives in Perovskite Solar Cells

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Rationally selection of precursor additives during perovskite crystallization is essential for obtaining high‐quality films and achieving high‐performance perovskite solar cells (PSCs). However, the discovery and optimization of effective additives still rely heavily on time‐consuming and costly trial‐and‐error experiments.

Research Progress and Prospect of Single‐Atom Materials in Tumor Catalytic Therapy

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Tumor catalytic therapy (TCT), an emerging therapeutic modality, exerts specific cytotoxic effects on tumor cells by catalyzing endogenous substances within the tumor microenvironment (TME)—including hydrogen peroxide (H2O2), glucose, and glutathione—to generate reactive oxygen species (ROS) or deplete protective biomolecules.

Dual Modulation of Schottky Barrier Height and Width Enables High‐Performance p‐Type MoTe2 Transistors

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Efficient hole injection at metal‐semiconductor interfaces remains a central challenge for high‐performance p‐type transistors based on two‐dimensional (2D) semiconductors. Although substantial efforts have been devoted to reducing Schottky barrier height through contact engineering, the barrier width is rarely addressed, thereby limiting ...

Time‐Efficient Columnar‐to‐Equiaxed Transition via High Magnetic Field Processing

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The need to simplify processing routes and improve processing efficiency motivates the development of time‐efficient methods for inducing the columnar‐to‐equiaxed transition (CET) during solidification while tailoring material performance. Conventional multistep CET approaches are time‐consuming and often struggle to simultaneously regulate ...

Tailoring a Dual‐Scale Heterostructure With γ‐Textures and Nano‐β0 Dispersion for Synergistic Enhancement of Mechanical Properties of TiAl Alloy

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The limited crack resistance of coarse grain boundaries and coarse interfaces leads to an incompatibility between high‐temperature strength and ductility in TiAl alloys. Tailoring stress‐oriented textures and multiscale heterogeneous interfaces can effectively impede crack propagation, thereby overcoming this trade‐off.

Abnormal Phase Transition Mechanism in the CoCrAlY Bond Coat Revealed by In Situ and Ex Situ Experiments

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →

补CO₂对高硬低碱水质电化学除硬的增强作用

Gongye shui chuli, 2023
针对典型高硬度、低碳酸盐碱度的煤气化灰水直接电化学除硬效果差的问题，提出在隔膜法电化学除硬之前预补加CO2来提升除硬效果。实验首先验证了该方法的可行性，然后在不同电流-流量条件下考察了CO2补加量对电化学除硬率、除硬速率、电流效率及能耗的影响。结果表明，补加CO2能明显提升除硬效果，在5 A-5 L/h电流-流量下，当补加CO2使总无机碳含量接近总硬度时，除硬率提升至60%左右，电流效率提升至50%，除硬速率提升至470 g/（m2·h）（以CaCO3计），去除单位质量CaCO3的能耗降至13.5 kW·

Ultrathin Magnetic–Conductive Heterostructures for Absorption‐Dominant Electromagnetic Interference Shielding

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...
