Eco‐Friendly N, S Co‐Doped Graphene Quantum Dots for Sensing 3‐Nitro‐L‐Tyrosine via Dark State Formation: Evidence From Photoluminescence and Single‐Particle Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents the selective optical sensing of 3‐Nitro‐L‐tyrosine (3NT), a biomarker associated with neurological and cardiovascular diseases, through the photoluminescence quenching of nitrogen and sulfur co‐doped graphene quantum dots (NS‐GQDs) obtained from garlic.

Ultrafast Electron Dynamics at the Water‐Modified InP(100) Surface

open access: yesAdvanced Materials Interfaces, EarlyView.
P‐rich indium phosphide is exposed to H2O at 200 °C, leading to water adsorption stabilized by hydroxyl groups. Time‐resolved two‐photon photoemission indicates an increase in electron lifetimes at the near‐surface conduction band minimum by at least an order of magnitude; this is correlated using Density‐functional theory to dampening of surface P ...

Fe(III)‐Mediated Formation of Cu Nanoinclusions and Local Heterojunctions in CuWO4 Photoanodes

open access: yesAdvanced Materials Interfaces, EarlyView.
Fe(III) mediates the self‐assembly of CuWO4 nanostructures into core–shell architectures with Cu inclusions and WO3‐rich shells, enabling local p–n junction formation. This nanostructural transformation enhances charge separation and enables dual activity: oxygen evolution under photoelectrochemical operation and reactive oxygen species (ROS ...

How to Manufacture Photonic Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Silicon‐Integrated Next‐Generation Plasmonic Devices for Energy‐Efficient Semiconductor Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Silicon (Si)‐integrated plasmonics offer a pathway to next‐generation, energy‐efficient semiconductor applications. This review highlights advances using complementary metal–oxide–semiconductor (CMOS)‐compatible materials like transparent conductive oxides and novel architectures, particularly coupled hybrid plasmonic waveguides (CHPWs).
