Book Description
Broad Funding Opportunity Announcement Project: ITN is addressing the high cost of electrochromic windows with a new manufacturing process: roll-to-roll deposition of the film onto flexible plastic surfaces. Production of electrochromic films on plastic requires low processing temperatures and uniform film quality over large surface areas. ITN is overcoming these challenges using its previous experience in growing flexible thin-film solar cells and batteries. By developing sensor-based controls, ITN's roll-to-roll manufacturing process yields more film over a larger area than traditional film deposition methods. Evaluating deposition processes from a control standpoint ultimately strengthens the ability for ITN to handle unanticipated deviations quickly and efficiently, enabling more consistent large-volume production. The team is currently moving from small-scale prototypes into pilot-scale production to validate roll-to-roll manufacturability and produce scaled prototypes that can be proven in simulated operating conditions. Electrochromic plastic films could also open new markets in building retrofit applications, vastly expanding the potential energy savings.

Book Description
Five Quads of energy are lost through windows annually in the U.S. Low-e coatings are increasingly employed to reduce the wasted energy. Most commonly, the low-e coating is an oxide material applied directly to the glass at high temperature. With over 100,000,000 existing homes, a retrofit product is crucial to achieve widespread energy savings. Low-e films, i.e. coatings on polymeric substrates, are now also available to meet this need. However, the traditional oxide materials and process is incompatible with low temperature plastics. Alternate high performing low-e films typically incorporate materials that limit visible transmission to 35% or less. Further, the cost is high. The objective of this award was to develop a retrofit, integrated low-e/electrochromic window film to dramatically reduce energy lost through windows. While field testing of state-of-the-art electrochromic (EC) windows show the energy savings are maximized if a low-e coating is used in conjunction with the EC, available low-e films have a low visible transmission (~70% or less) that limits the achievable clear state and therefore, appearance and energy savings potential. Comprehensive energy savings models were completed at Lawrence Berkeley National Lab (LBNL). A parametric approach was used to project energy usage for windows with a large range of low-e properties across all U.S. climate zones, without limiting the study to materials that had already been produced commercially or made in a lab. The model enables projection of energy savings for low-e films as well as integrated low-e/EC products. This project developed a novel low-e film, optimized for compatibility with EC windows, using low temperature, high deposition rate processes for the growth of low-e coatings on plastic films by microwave plasma enhanced chemical vapor deposition. Silica films with good density and optical properties were demonstrated at deposition rates as high as 130Å/sec. A simple bi-layer low-e stack of silica and a transparent conductive oxide demonstrated 90% visible transmission with high thermal infrared reflectivity characteristic of conventional low-e coatings. A slightly more complex stack provided high solar infrared reflection without sacrificing visible transmission or thermal infrared reflection. Successful completion of the effort produced a prototype integrated low-e, dynamic window film with characterized energy saving potential. Cost modeling for the passive bi-layer, low-e film projects a manufacturing cost of ~$0.50/ft2 for a plant with 10M ft2/yr capacity. The novel thin film processes developed here enable high deposition rate (low cost), optical quality oxide coatings at low temperatures. When combined with engineered materials, ITN's coating will result in low-cost, low-e films that reflect a high degree of infrared radiation without substantially reducing the visible transmission. The resultant window film will improve the U-value and achieve SHGC improvements over bare glass. The new low-e coating will be particularly attractive when combined with an electrochromic film. Low-e coating design guided by energy savings modeling allows customization of the product for different climate zones.

Book Description
Evidently, electrochemical sensing has revolutionized the electroanalytical detections in the world. Since the 19th century, a huge amount of growth has been visible on various fronts, such as biosensors, energy devices, semiconductor devices, communication, embedded systems, sensors etc. However, the major research gap lies in the fact that most of the reported literatures are bulk systems; hence there are limitations for practical applications. Research in these domains has been carried out by both academia and industry, whereby academics is the backbone whose intellectual outputs have been widely adopted by the industry and implemented for consumers at large. In order to impart portability to the electrochemical sensors for point-of-care application, the collaboration of electrochemistry, microfluidics, electronics and communication as an interdisciplinary forum is crucial. The miniaturization, automation, IoT enabling and integration are the requirements for building the mentioned research gap. The conversion of electrochemical sensing theoretical concepts to practical applications in real time via miniaturization and integration of microfluidics will enhance this domain. In this context, of lately, several research groups have developed miniaturized microdevices as electrochemical-sensing platforms. This has led to a demand of offering a reference book as a guideline for the PhD programs in electrochemistry, MEMS, electronics and communication. Undoubtedly, this will have a huge impact for R&D in industries, public-funded research institutes and academic institutions. The book will provide a single forum to understand the current research trends and future perspectives of various electrochemical sensors and their integration in microfluidic devices, automation and point-of-care testing. For students, the book will become a motivation for them to explore these areas for their career standpoints. For the professionals, the book will become a thought-provoking stage to manoeuvre the next-generation devices/processes for commercialization.
