    Carbon nanotubes: present and future commercial applications (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-02-02
    Description: Worldwide commercial interest in carbon nanotubes (CNTs) is reflected in a production capacity that presently exceeds several thousand tons per year. Currently, bulk CNT powders are incorporated in diverse commercial products ranging from rechargeable batteries, automotive parts, and sporting goods to boat hulls and water filters. Advances in CNT synthesis, purification, and chemical modification are enabling integration of CNTs in thin-film electronics and large-area coatings. Although not yet providing compelling mechanical strength or electrical or thermal conductivities for many applications, CNT yarns and sheets already have promising performance for applications including supercapacitors, actuators, and lightweight electromagnetic shields.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Volder, Michael F L -- Tawfick, Sameh H -- Baughman, Ray H -- Hart, A John -- New York, N.Y. -- Science. 2013 Feb 1;339(6119):535-9. doi: 10.1126/science.1222453.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉imec, 3001 Heverlee, Belgium. michael.devolder@imec.be〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23372006" target="_blank"〉PubMed〈/a〉

    Scalable electrochromic nanopixels using plasmonics (2019)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2019
    Description: 〈p〉Plasmonic metasurfaces are a promising route for flat panel display applications due to their full color gamut and high spatial resolution. However, this plasmonic coloration cannot be readily tuned and requires expensive lithographic techniques. Here, we present scalable electrically driven color-changing metasurfaces constructed using a bottom-up solution process that controls the crucial plasmonic gaps and fills them with an active medium. Electrochromic nanoparticles are coated onto a metallic mirror, providing the smallest-area active plasmonic pixels to date. These nanopixels show strong scattering colors and are electrically tunable across 〉100-nm wavelength ranges. Their bistable behavior (with persistence times exceeding hundreds of seconds) and ultralow energy consumption (9 fJ per pixel) offer vivid, uniform, nonfading color that can be tuned at high refresh rates (〉50 Hz) and optical contrast (〉50%). These dynamics scale from the single nanoparticle level to multicentimeter scale films in subwavelength thickness devices, which are a hundredfold thinner than current displays.〈/p〉
