    Elastic photonic hydrogels (EPHs) with one-dimensional ordered chain-like colloidal crystal arrays of magnetically active monodisperse nanoclusters are synthesized, and exhibit versatile mechanochromic behavior with advanced sensitivity and interesting potentials for touch sensing, color-based switching, and flexible displays.

  2. Hollow Plasmonic U-Cavities with High-Aspect-Ratio Nanofins Sustaining Strong Optical Vortices for Light Trapping and Sensing

    Coupling of ridge hot spots with a scalable resonant U-cavity fully traps light in intense optical vortices, generating strong and sharp resonances with widths as small as 14 nm. Tunable resonance wavelengths from visible to near-infrared are achieved by controlling the cavity dimensions. Sensing performance with a figure of merit of 136 is attained and biosensing in a protein-ligand scheme is demonstrated.

  3. Injection Molding of Free-Standing, Three-Dimensional, All-Metal Terahertz Metamaterials

    Jinqi Wang, Shuchang Liu, Sivaraman Guruswamy and Ajay Nahata

    Article first published online: 17 APR 2014 | DOI: 10.1002/adom.201400094

    Free-standing two- and three-dimensional terahertz metamaterials are fabricated via injection molding of gallium, a metal that melts at temperatures just slightly above room temperature. The liquid metal is injected into elastomeric molds in which the desired geometry is inscribed. The metal does not solidify when cooled below the freezing temperature, but rather requires contact with a solid piece of gallium metal to do so.

  4. Class Ceramics: Tuneable Nanostructuring of Highly Transparent Zinc Gallogermanate Glasses and Glass-Ceramics (Advanced Optical Materials 4/2014) (page 402)

    Sébastien Chenu, Emmanuel Véron, Cécile Genevois, Guy Matzen, Thierry Cardinal, Auriane Etienne, Dominique Massiot and Mathieu Allix

    Article first published online: 14 APR 2014 | DOI: 10.1002/adom.201470026

    Highly transparent nanostructured gallogermanatebased glass and glass-ceramic materials are reported on page 364 by M. Allix and co-workers. These materials present nanoscale phase separations, whose size can be tailored depending on the nominal composition. The large variety of accessible compositions combined with precise control of the nanostructure offer a great opportunity to design new highly transparent nanostructured materials with a wide range of tuneable optical properties both in the visible and the infrared ranges.
