Biomimetic TME‐Responsive Nanotheranostics for Precise NIR‐II Ratiometric Photoacoustic Imaging and Synergistic Immuno‐Photothermal Therapy

Small, EarlyView.
A biomimetic Au/Ag@HMON‐NLG@CCM nanotheranostic is engineered for tumor microenvironment‐responsive NIR‐II ratiometric photoacoustic imaging and immune‐photothermal therapy. The integration of hyperthermia‐triggered immunogenic cell death with IDO‐blockade‐mediated metabolic remodeling promotes dendritic cell maturation and T‐cell activation.

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.
