Acoustically Assisted Heterojunction Hydrogel Promotes Angiogenesis and Tissue Regeneration by Modulating the Inflammatory Microenvironment

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The healing of diabetic chronic wounds is hindered by multiple pathological barriers, including oxidative stress imbalance induced by hyperglycemia, persistent bacterial infection, and impaired neovascular function. This study developed an F127–HA–BiOCl@CeO2 (FHBC) hydrogel dressing with acoustic responsiveness, achieving tissue repair through

Dual‐Bioactive Lignin‐Based Microcarrier Hydrogel Platform via Metal Salt Crosslinking for Synchronized Infection Eradication and Bone Regeneration

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.

Microwave‐Actuated CuS/CuCo2O4 Heterojunction Microneedles for Synergistic Eradication of Deep‐Seated Biofilms and Inflammatory Microenvironment Remodeling in Acne Treatment

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Deep skin infections and dense biofilm barriers caused by Propionibacterium acnes (P. acnes) remain significant challenges in recurrent acne vulgaris, exacerbated by the poor stratum corneum penetration of conventional therapies and rising antibiotic resistance.

An Organo‐Pt(II) Photosensitizer With Robust Photo‐Assisted Antibacterial and Wound Recovery Performances in Diabetic Mice Wound Model

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The pathogenesis of diabetic foot ulcers is complex, often involving polymicrobial infection and persistent inflammatory responses, which lead to delayed or nonhealing wounds, posing a formidable clinical challenge. Existing photodynamic therapy reagents and traditional treatments generally address only a single pathological aspect, and the ...

Millimeter/Nano‐Structured Metal Monolithic Catalysts: A Privileged Opportunity for Sustainable Water Purification

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

3D Printed High‐Strength Hydrogel for Dual Release of Cu2+ and Ag+ Ions to Enhance Bone Repair and Antibacterial Properties

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.

Titanium Implant Abutments With Polydopamine‐Mesoporous Cerium Dioxide Coatings for Enhanced Antibacterial, Anti‐Inflammatory, and Soft Tissue Integration Properties

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.
