Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The strength and ductility trade‐off in titanium matrix composites (TMCs) is a critical factor limiting their widespread application. In this study, a (TiB + TiC)/Ti–6Al–4V composite with an optimal balance between strength and ductility was engineered via multi‐directional forging.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The precise quantification of cytokines is crucial for monitoring disease onset and progression. Herein, we developed a synergistic signal amplification approach by utilizing nanoreactor‐encapsulated CeO2 nanozymes, which were in situ electrodeposited within the mesoporous silica nanochannel film (SNF) grown on indium tin oxide (ITO ...
