TL;DR: A transmissive type of electrochromic (EC) device for antiglare purpose was developed by using cathodically coloring tungsten oxide (W03) and anodically color- ing Prussian blue (PB) as discussed by the authors.
Abstract: The glazed areas in automobiles are increasing in size.' As the glass area grows larger, we need better solar control to maintain comfort for the occupants and to reduce the need for larger air, conditioners. For solar control, we need to filter out infrared energy that causes heat buildup,2 control visible light and block out ultraviolet energy. To control visible light, devices using photochromism, liquid crystal, thermochromism and electrochrornism have been studied.3 We developed a transmissive type of electrochromic (EC) device (for antiglare purpose) by using cathodically coloring tungsten oxide (W03) and anodically color- ing Prussian blue (PB). Recently a practical antiglare mirror for automotive use has been put on the market,'\" but large scale EC device for automobiles is still under development.

TL;DR: A physical model proposed by Gunn, Allison and Abbott (GAA) to utilize electromagnetic waves for eavesdropping on the Kirchhoff-law–Johnson-noise (KLJN) secure key distribution is refuted and the correct mathematical model of the GAA scheme is deduced, based on impedances at the quasi-static limit.
Abstract: We refute a physical model, recently proposed by Gunn, Allison and Abbott (GAA) (http://arxiv.org/pdf/1402.2709v2.pdf), to utilize electromagnetic waves for eavesdropping on the Kirchhoff-law-Johnson-noise (KLJN) secure key distribution. Their model, and its theoretical underpinnings, is found to be fundamentally flawed because their assumption of electromagnetic waves violates not only the wave equation but also the Second Law of Thermodynamics, the Principle of Detailed Balance, Boltzmann's Energy Equipartition Theorem, and Planck's formula by implying infinitely strong blackbody radiation. We deduce the correct mathematical model of the GAA scheme, which is based on impedances at the quasi-static limit. Mathematical analysis and simulation results confirm our approach and prove that GAA's experimental interpretation is incorrect too.

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.
