Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies
Advanced Optical Materials, EarlyView.A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.

Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors
Advanced Optical Materials, EarlyView.Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

Size Effect on Photothermal Heating Ability of Gold Bipyramids
Advanced Optical Materials, EarlyView.Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...
