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

Advanced 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

Advanced 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 ...

Nitrogen‐Doped Amorphous Carbon Film for Enhanced Cu2+ Electrochemical Sensing in Marine Environments

Advanced Materials Interfaces, EarlyView.
Large‐area N‐doped amorphous carbon films are synthesized at room temperature via hybrid linear ion source technique. Nitrogen doping promotes the formation of sp2−C and C‐N bonds, thus enhancing the electrode's sensitivity. These electrodes achieve ultra‐low Cu2+ detection (8 × 10−3 mM) in 3.5 wt% NaCl and exhibit excellent stability/repeatability for
