Calcium‐Engineered Copper/Palladium Nanozyme With Reactive Oxygen Species/Nitric Oxide Dual‐Burst for Enhancing Immunotherapy via Multiple‐Inducing Calcium Overload

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Calcium overload‐induced immunogenic cell death (ICD) holds great potential in antitumor immunotherapy, and it is a critical strategy for regulating multiple intracellular Ca2+ channels through inhibiting the endogenous Ca2+ efflux and promoting the exogenous Ca2+ influx.

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

open access: yesRare 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.

The Evolution of Metal Halide Perovskite Transistors

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Metal halide perovskites (MHPs) offer a revolutionary pathway for next‐generation field‐effect transistors (FETs) because of their exceptional carrier mobilities and cost‐effective processability. However, their transition to practical electronics is significantly challenged by intrinsic instability and imbalanced charge transport. This review

Synergistic Effect of Hydrophilic Surface and Nano‐Ag2O in TiO2‐Based Composites Coating on Antibacterial and Osteogenic Properties of Low Modulus Ti‐Mo‐Ag Alloy

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...

Ultrasound‐Driven Dual Piezocatalytic–Electrical Scaffold Synergistically Promotes Osteoporotic Bone Healing

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The regeneration of osteoporotic bone defects is severely hampered by compromised endogenous healing capacity, demanding advanced strategies that actively orchestrate pro‐osteogenic microenvironments. Here, we report an integrated, self‐powered osteo‐regenerative system that uniquely leverages a dual ultrasound‐responsive piezoelectric ...
