Solvent‐Free Synthesis of Ultrabright Carbon Dots With Near‐Unity Quantum Yield for High‐Performance Light‐Emitting Diodes

Advanced Science, EarlyView.
A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Van der Waals Gap‐Confined Molecular Engineering of MoS2 for Selectivity‐Enhanced and Humidity‐Tolerant Gas Sensing

Advanced Science, EarlyView.
Molecular confinement within van der Waals gaps of MoS2 is established as a powerful design strategy for selective and stable chemical sensing. Ethanol‐confined films simultaneously tune electronic doping, surface wettability, and sulfur vacancy configurations, suppressing water interference while enhancing NO2 adsorption.

Opposite Trap‐State Evolution Pathways Govern Endurance and Retention Failure in Amorphous Chalcogenide Memory

Advanced Science, EarlyView.
GeSbSe selector‐only memory devices are investigated through physical and electrical analyses to reveal opposite trap‐state evolution pathways governing reliability degradation. Endurance cycling drives Se migration, transitioning traps from deep to shallow states.
