Flexible Leaf‐Like Fuel Cell From Plasmonic Janus Nanosheet

Advanced Functional Materials, EarlyView.
A flexible leaf‐like fuel cell is fabricated by conductive gold nanowire sponge‐supported plasmonic Janus nanosheet, which can generate a power of 8.93 mW cm⁻2 with less than 10% performance deterioration even being bent or twisted. Further assembly in a tree‐like layout demonstrates omnidirectional light harvesting capability and wind resistance ...

Dye‐Sensitized Solar Cells Inspired Method to Modulate Photo‐Induced Charge Transfer Efficiency for Enhancing the SERS Activity of Semiconductor

Advanced Materials Interfaces, EarlyView., 2023
The conduction band (CB) edge and surface state energy level of TiO2 nanoparticles shift downward with increasing Li+ concentration, which facilitates the charge‐transfer interaction between the molecules and the surface enhanced Raman scattering substrates. Abstract While the Lithium ion modification strategy is widely adopted in tuning the bandgap of

Multi‐Pathway Upconversion Emission in Symmetry‐Broken Nanocavities: Broadband Multiresonant Enhancement and Anti‐Correlated Interfacial Sensitivity

Advanced Functional Materials, EarlyView.
Symmetry‐broken plasmonic nanoantenna arrays achieve broadband multiresonant enhancement of second harmonic generation (SHG), third harmonic generation (THG), and upconversion photoluminescence (UCPL), under femtosecond laser excitation across the near‐infrared range (1000–1600 nm).

Boosting the Figure Of Merit of LSPR-based refractive index sensing by phase-sensitive measurements

, 2012
Localized surface plasmon resonances possess very interesting properties for a wide variety of sensing applications. In many of the existing applications only the intensity of the reflected or transmitted signals is taken into account, while the phase ...

High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide

Advanced Functional Materials, EarlyView.
This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

Advanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.
