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).

Spin‐Selective Anisotropic Magnetoresistance Driven by Chirality in DNA

Advanced Functional Materials, EarlyView.
It is shown that magnetoresistance (MR) measurements carried out as a function of angular dependence between the magnetic field and a chiral (DNA) interface provide a valuable new insight into the charge transport mechanism associated with the chiral‐induced spin selectivity (CISS) effect.

Patterned Assembly of Transition Metal Dichalcogenide/Graphene Heterostructures via Direct Laser Writing

Advanced Functional Materials, EarlyView.
The fabrication of patterned transition metal dichalcogenide (TMD)/graphene heterostructures via direct laser writing reveals new interface chemistry and enables efficient, customizable assembly. Selective laser irradiation of functionalized TMD/graphene triggers localized reactions, forming chemically modified interfaces.
