Advancements in Carbon‐Based Piezoelectric Materials: Mechanism, Classification, and Applications in Energy Science

open access: yesAdvanced Materials, EarlyView.
Carbon‐based piezoelectric materials are systematically categorized based on their structural and functional properties. The mechanisms of stress‐induced charge transfer are elucidated, and their applications are explored across three key domains: piezoelectric catalysis for energy conversion and environmental remediation, piezoelectric biomedical ...

Nanometer Resolution Structure‐Emission Correlation of Individual Quantum Emitters via Enhanced Cathodoluminescence in Twisted Hexagonal Boron Nitride

open access: yesAdvanced Materials, EarlyView.
Nanometer‐resolution mapping of individual quantum emitters in hexagonal boron nitride is achieved, allowing us to identify the 440 nm blue emitter as a substituted vertical carbon dimer. Leveraging this atomic‐level insight, the deterministic creation of isolated single 440 nm blue emitters is demonstrated through localized electron beam irradiation ...

Carbon Fiber Oxidation in 4D

open access: yesAdvanced Materials, EarlyView.
The oxidation of porous carbon fiber heat shield material at high temperatures is imaged using time‐resolved synchrotron X‐ray microtomography. Resolving the interplay between species diffusion and carbon‐oxygen reaction rate reveals spatially and temporally varying degradation across oxidation regimes, with profound implications for in‐depth material ...

Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

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

open access: yesAdvanced 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 ...

Unperceivable Designs of Wearable Electronics

open access: yesAdvanced Materials, EarlyView.
Unperceivable wearable technologies seamlessly integrate into everyone's daily life, for healthcare and Internet‐of‐Things applications. By remaining completely unnoticed both visually and tactilely, by the user and others, they ensure medical privacy and allow natural social interactions.

Probing and Tuning Strain‐Localized Exciton Emission in 2D Material Bubbles at Room Temperature

open access: yesAdvanced Materials, EarlyView.
This work provides an approach: 1) to directly visualize the associated exciton properties, revealing an intrinsic emission wavelength shift, and 2) actively modify local strain, enabling further exciton emission tuning. These findings provide direct insights into the strain‐localized emission dynamics in bubbles and establish a robust framework for ...
