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 ...

Advanced Materials, EarlyView.A titania‐supported Co1/Ru single‐atom alloy catalyst enables efficient polypropylene hydrogenolysis. Ru─Co─Ru motifs maintain Ru activity while suppressing excessive chain scission to gaseous products. Both virgin and waste plastics achieve high, environmentally and economically optimal C11+ liquid yields, supporting sustainable chemical recycling ...

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum
Advanced Materials, EarlyView.Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...
