Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

Advanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...

Skeletal High‐Strength Nanoporous Copper and Metamaterials: The Hakka Tulou Design Heritage

Advanced Materials, EarlyView.
Inspired by the Hakka Tulou walls, skeletal nanoporous copper is fabricated via a two‐phase MnCu precursor and controlled dealloying. This strategy achieves high strength (200 MPa) and large specific surface area (27.6 m2/g), and extends to lattice metamaterials with hierarchical porosity, offering new design pathways for multifunctional metal ...

Intensive Widmannstätten Nanoprecipitates Catalyze SnTe With State‐of‐the‐Art Thermoelectric Performance

Advanced Materials, EarlyView.
The intensive lath‐shaped Ag2Te Widmannstätten nanoprecipitates are in situ generated in SnTe via AgPbSbTe3 alloying, and align with the formation of the parallel type and twin type interfaces. These Widmannstätten nanoprecipitates effectively scatter phonons to reduce the lattice thermal conductivity, resulting in a significantly enhanced average ZT ...

Triboelectric Nanogenerators Enable Multifunctional Ice Accretion, Melting, and Interfacial Fracture Detection

Advanced Materials, EarlyView.
Water impacting, freezing, melting, and being mechanically removed from the designed dielectric surfaces generates a triboeletric signal that can be used to detect various icing and de‐icing scenarios. The charge transferred directly scales with the interfacial fracture mechanism, further validating triboelectricity as an excellent ice‐detection ...

3D Acoustic Imaging Hitting the Diffraction Limit via Fully Parameter‐Optimized Meta‐Lens and Frequency‐Domain Reconstruction

Advanced Materials, EarlyView.
This article employs a binary genetic algorithm to design an ultra‐fine ultrasonic meta‐lens, achieving lateral super‐resolution imaging in the far field (>20λ₀). Building on this, longitudinal resolution is effectively restored through frequency domain reconstruction.
