Second‐Harmonic Hyper‐Mie Optical Activity Enables Closed‐Loop Chiral Photochemistry
Advanced Materials, EarlyView.Nonlinear chiral photochemistry is demonstrated in CdTe/CdO nanohelices, where circularly polarized infrared light both drives and tracks photo‐oxidation via second‐harmonic scattering. This closed‐loop process reveals real‐time structural evolution, including shell fracturing and core exposure, accompanied by a transition from hyper‐Mie to hyper ...

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment
Advanced Materials, EarlyView.ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...

Advanced Materials Interfaces, EarlyView.We report electrochemical quantum capacitance spectroscopy as an ambient, in situ probe for defect‐mediated electronic structure at 2D material interfaces. Using monolayer MoS2, the method resolves band edges and vacancy states, tracks sulfur‐vacancy evolution during hydrogen evolution, and links interfacial density‐of‐states changes to nearly ...

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials
Advanced Materials Interfaces, EarlyView.Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...
