Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications
Advanced Functional Materials, EarlyView.Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna
Advanced Functional Materials, EarlyView.We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...
