GaSex Nanoparticles Modulate Neutrophil Function and Mitigate NET‐Driven Osteogenic Impairment in Osteomyelitis Therapy

Advanced Materials, EarlyView.
Neutrophil extracellular traps (NETs) emerge as a critical repair‐limiting factor in osteomyelitis, driving osteoblast mitochondrial dysfunction and excessive PINK1/Parkin‐mediated mitophagy. Gallium–selenium nanoparticles (GaSex) scavenge reactive oxygen species, redirect neutrophils from NETosis toward bactericidal phagocytosis, eliminate methicillin‐

BiFeO3-doped (Na0.5K0.5)NbO3 lead-free piezoelectric ceramics

Science and Technology of Advanced Materials, 2008
Lead-free piezoelectric ceramics (1−x)(Na0.5K0.5)NbO3-xBiFeO3 (x=0~0.07) were synthesized by the solid-state reaction. Differential scanning calorimetry (DSC) measurements revealed that an increase in the amount of BiFeO3 dopant resulted in a decrease in

Interface Dynamics in Biomolecular Condensates by High‐Speed AFM

Advanced Materials Interfaces, EarlyView.
High‐speed atomic force microscopy provides nanoscale structural dynamics at the liquid interface of biomolecular condensates, key elements in several cellular pathways. By addressing the challenges of low surface tension and condensate‐induced instabilities, we achieve nanometer spatial and sub‐second temporal resolution, revealing structural ...

Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials

Advanced Materials Interfaces, EarlyView.
Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...
