Infrared emissivity properties of infrared stealth coatings prepared by water-based technologies

Optical Materials Express, 2016
The infrared stealth coatings were prepared using water-based techniques composed of aluminum powder with different particles sizes (325 mesh, 500 mesh, 800 mesh, 1000 mesh, 1200 mesh, 1500 mesh) embedded in different matrix resins (acrylic resin, epoxy resin and polyurethane resin). The relationship between the type and the viscosity of resins and the

Electron compensation‐gated nanomotor for immunomodulation and microenvironment remodeling in bacterial pneumonia therapy

BMEMat, EarlyView.
A nanomotor featuring an “electronic lock” via electron compensation in an Au‐Ag alloy ensures therapeutic precision. Near‐infrared light acts as a key, unlocking on‐demand Ag+ release for synergistic bactericidal action and microenvironment remodeling to potently treat bacterial pneumonia. Abstract Bacterial pneumonia treatment is severely hampered by

Wood‐Derived 3D Conductive Cellular Bio‐C@YB2C2 Ceramics for Efficient Electromagnetic Shielding and Joule Heating

Electron, EarlyView.
Herein, a biomimetic, anisotropic, robust wood‐derived 3D conductive Bio‐C@YB2C2 framework was synthesized by in situ boron/carbon thermal reduction reaction on the carbonized wood template. The as‐obtained Bio‐C@YB2C2 composites accurately inherit the specific microstructure of natural wood, providing pathways for terahertz wave dissipation.
