Light‐Harvesting Photothermal Hotspots Enabled by NIR Scattering‐Absorption Coupling

Advanced Science, EarlyView.
By coupling the broadband scattering of nanodiamonds with the plasmonic absorption of gold nanostars, this work proposes a novel strategy for the active modulation of photon transport. This strategy creates localized photothermal hotspots in turbid media and achieves a supra‐additive heating efficiency, thereby providing a universal platform for low ...

Bioinspired Cold‐Laminated Ultrathin Hydrogels as a Broadly Adaptive Platform for Physiological Monitoring

Advanced Science, EarlyView.
A cold‐lamination strategy is introduced to fabricate ultrathin, nanomesh‐reinforced hydrogel bioelectronics with controlled thickness, tunable mechanics, and reversible adhesion. By mechanically interlocking a TPU nanomesh within a temperature‐responsive hydrogel, the platform enables robust epidermal and implantable cardiac interfaces, supporting ...

Nanocurvature‐Activated Dipolar Polarization in M–N4 Single‐Atom Sites for High‐Performance Electromagnetic Wave Absorption

Advanced Science, EarlyView.
Increasing nanocurvature effectively enriches the local electron density of the M–N4 motif, which facilitates electron transfer from the metal center to nitrogen atoms. This electronic behavior intensifies the localization and asymmetric distribution of charge, thereby significantly amplifying the dipole moment and polarizability.
