TL;DR: In this article, a transparent electrochromic device was made by coating conducting glass with reactively evaporated tungsten oxide films and letting these specimens form the working electrode in an electrochemical cell containing an electrolyte of LiClO4 + propylene carbonate.

TL;DR: This paper attempts to give an introduction to "smart windows" technology, which finally seems to be ready for large-scale applications from the viewpoints of materials, device technology, low-cost manufacturing aspects, and applications to buildings as well as niche products.

TL;DR: A comprehensive list of annotated references on surfaces which combine high solar absorptance with low thermal emittance is presented in this article, covering the period 1955-1981, covering papers printed in scientific journals and in published conference proceedings.
Abstract: A comprehensive classified list of annotated references on surfaces which combine high solar absorptance with low thermal emittance is presented, covering the period 1955–1981. The list embraces papers printed in scientific journals and in published conference proceedings. An index of authors and on surface coatings studied is appended.

TL;DR: In this article, the effective medium theory was extended by incorporating dipole-dipole interactions to account for local field effects, represented approximately by use of effective depolarization factors.
Abstract: We extend the old effective-medium theory, originally due to Bruggeman, by incorporating dipole-dipole interactions to account for local-field effects. The interactions are represented approximately by use of effective depolarization factors. For close-packed clusters of conducting regions, a description which is appropriate at the percolation threshold, we predict an onset of percolation processes when 15.6 vol% is conducting. This is in very good agreement with numerical simulations as well as with experimental data for the metal-insulator transitions in metal-ammonia solutions and in alkali-tungsten bronzes.

TL;DR: Graphene has high mobility and optical transparency, in addition to flexibility, robustness and environmental stability as discussed by the authors, and its true potential lies in photonics and optoelectronics, where the combination of its unique optical and electronic properties can be fully exploited, even in the absence of a bandgap, and the linear dispersion of the Dirac electrons enables ultrawideband tunability.
Abstract: The richness of optical and electronic properties of graphene attracts enormous interest. Graphene has high mobility and optical transparency, in addition to flexibility, robustness and environmental stability. So far, the main focus has been on fundamental physics and electronic devices. However, we believe its true potential lies in photonics and optoelectronics, where the combination of its unique optical and electronic properties can be fully exploited, even in the absence of a bandgap, and the linear dispersion of the Dirac electrons enables ultrawideband tunability. The rise of graphene in photonics and optoelectronics is shown by several recent results, ranging from solar cells and light-emitting devices to touch screens, photodetectors and ultrafast lasers. Here we review the state-of-the-art in this emerging field.
