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 structurally stable anodes with high capacities and long cycle lives is essential for the development of potassium–ion batteries. Conversion‐type anodes have attracted considerable attention in potassium–ion batteries (PIBs) due to their high theoretical capacities.
