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‐

Surface Functionalization Modulates Collective Cell Behavior Near Topological Defects Induced by Topographical Patterning

Advanced Materials Interfaces, EarlyView.
Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...

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 ...

Cellulose Surface Modification Effects on Equilibrium and Non‐Equilibrium Wetting by Water

Advanced Materials Interfaces, EarlyView.
Molecular dynamics simulations of nanometer‐sized water droplets spreading on cellulose substrates show strong effects from surface chemistry on both equilibrium contact angles and spreading dynamics. ABSTRACT Chemical modification is an important route to tuning interactions between nanocellulose and its surrounding media. Specifically, it affects the

SPECKLE MEASUREMENTS WITH A CCD ARRAY: APPLICATIONS TO SPECKLE REDUCTION.

, 1982
Speckle noise is an integral part of any laser projection display because it is the nature of laser (coherent) illumination to form interference patterns with high visibility.

Reduced Graphene Oxide Enhances the Vascular Organization and Contractile Performance of Fibrin‐Gelatin‐Based Engineered Cardiac Tissue

Advanced Materials Interfaces, EarlyView.
Fibrin–gelatin hydrogels functionalized with reduced graphene oxide create a mechanically stable and bioactive 3D environment for engineered cardiac tissue. The composite matrix promotes endothelial lumen formation, enhances sarcomeric protein expression, and increases contractile performance of embedded cardiomyocytes.
