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

The Effect of Geometrical and Material Modification of Sound Diffusers on Their Acoustic Parameters
Archives of Acoustics, 2013 Sound diffusers, in particular those based on changes in the phase of the reflected wave (Schroeder diffusers), have recently gained greatly in popularity in acoustics as an effective means to eliminate defects and improve the acoustic performance of ...

Ultra‐High Sensitivity, Wide‐Range Thermometry Based on High‐Quality Microscale Diamond Resonators
Advanced Materials, EarlyView.By combing high‐crystal quality single‐crystal diamond MEMS cantilevers with multi‐mode resonance, the groundbreaking microscale ultra‐high sensitivity ≈22 nK Hz−1/2 and resolution of 100 µK thermometry is achieved. The diamond MEMS thermometry can operate over a wide temperature range from 6.5 to 380 K. This work underscores diamond MEMS resonators as

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 ...

Interactions Between Active Matters and Endogenous Fields
Advanced Materials, EarlyView.This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...
