The Role of Porosity in SERS

open access: yesAdvanced Optical Materials, EarlyView.
This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique

Supraballs Composed of Mie‐Resonant Silicon Nanospheres

open access: yesAdvanced Optical Materials, EarlyView.
Spherical supraballs composed of Mie‐resonant silicon nanospheres are developed through an emulsion‐templated self‐assembly process. By systematically varying constituent silicon nanosphere size and interparticle spacing—both statically through oxidation and dynamically using thermoresponsive shells—the reflection color and intensity of the supraballs ...

Directional Light Scattering In Mie‐Resonant Si Particles With Ultra‐Thin Au Shells

open access: yesAdvanced Optical Materials, EarlyView.
Si@Au core‐shell particles have been produced to study their ability to directionally scatter light. We found that the heavily reported particulate shells do not overlap the electric and magnetic dipoles well, where continuous shells have better overlap. Experimental analyses, including nanomaterial characterization, EELS and single‐particle dark‐field

N‐Containing Carbon Materials in Metal‐Free and Non‐Noble Metal Liquid Phase Heterogenous Catalysis

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Over 100 examples of non‐noble metal supported on N‐containing and metal‐free N‐containing carbon catalysts are discussed. Particular emphasis is put on how different N‐functionalities influence catalyst performance and stability. Preparation procedures are also examined, with a strong focus on how the heat treatment temperature influences N ...
