TL;DR: In this article, the authors survey and show earlier results about three different ways of fluctuation-enhanced sensing of bio agent, 1) the phage-based method for bacterium detection, 2) sensing and evaluating the odors of microbes, and 3) spectral and amplitude distribution analysis of noise in light scattering to identify spores based on their diffusion coefficient.
Abstract: We survey and show our earlier results about three different ways of fluctuation-enhanced sensing of bio agent, 1) the phage-based method for bacterium detection published earlier; 2) sensing and evaluating the odors of microbes; and 3) spectral and amplitude distribution analysis of noise in light scattering to identify spores based on their diffusion coefficient.

TL;DR: In this article, the basics of the two technologies focusing on functional principles, relevant materials, device and manufacturing technology, as well as selected results from research and development are outlined, including functional principles and relevant materials.
Abstract: Electrochromic and thermochromic materials and devices make it possible to construct glazings whose throughput of visible light and solar energy can be switched to different levels depending on the application of an electrical voltage or on the temperature, respectively These glazings are of much interest for eco-efficient buildings and are able to impart energy efficiency jointly with indoor comfort The present chapter outlines the basics of the two technologies focusing on functional principles, relevant materials, device and manufacturing technology, as well as selected results from research and development

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.
