TL;DR: In this paper, basic electrochromic (EC) device designs, useful oxide materials and their nanostructures, and elements of a theoretical description of the EC phenomenon are surveyed.
Abstract: Electrochromics is a key “green” technology for massive energy savings in the built environment jointly with indoor comfort. This paper surveys basic electrochromic (EC) device designs, useful oxide materials and their nanostructures, and elements of a theoretical description of the EC phenomenon. It also outlines critical manufacturing technologies and their pros and cons. Focus is on EC foil technology, which is shown capable of mass fabrication via roll-to-roll web coating and continuous lamination.

01 Jun 1973TL;DR: Localized phonon modes in quench-condensed Pb.9In.1 films, annealed at several temperatures up to 300 K, were studied by the method of superconductive tunneling as mentioned in this paper.
Abstract: Localized phonon modes in quench-condensed Pb.9In.1 films, annealed at several temperatures up to 300 K, were studied by the method of superconductive tunneling. No localized modes could be seen in very disordered films. Structure from such modes first appeared as the crystallite grains size increased.

TL;DR: In this article, a collection of methods to extract information from these microfluctuations is presented, called Fluctuation-Enhanced Sensing (FES) and two types of applications are discussed.
Abstract: Both selectivity and sensitivity of chemical sensors can be significantly improved by exploiting the information contained in microfluctuations present in the sensor system We call our collection of methods to extract information from these microfluctuations Fluctuation-Enhanced Sensing (FES) In this review paper we discuss general FES principles and two types of applications; gas sensing with commercial solid state sensors and the Sensing of Phage-Triggered Ion Cascde (SEPTIC) technique to detect and identify bacteria

TL;DR: In this paper, WO3 nanowires decorated with gold nanoparticles (AuNPs) were used in resistive gas sensor devices to detect ethanol by use of fluctuation enhanced sensing (FES).
Abstract: WO3 nanowires (WO3-NWs) decorated with gold nanoparticles (AuNPs) were utilized in resistive gas sensor devices to detect ethanol by use of fluctuation enhanced sensing (FES). The experimental system records both DC resistance and fluctuations of the sensing film. Our data verify that the sensitivity and selectivity of the gas sensor are improved by applying FES when the sensor is stimulated with a combination of UV light and heating. We conclude that UV light can produce improved gas sensing at low operating temperatures for the investigated AuNPdecorated WO3-NWs films.

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.
