Lifelike Pedagogy
What will children educated through life be capable of in the future? Only an educational approach based on real experiences, when the students decide and learn through the achievement of their own enterprises, prepares them for the challenges brought by the future. It must be taught not only basic school content, but also how to deal with the life challenges and opportunities, preparing real independent, creative, self-confident and happy people.
Fabrication of dye-sensitized solar cells using natural dyes extracted from Brazilian plants
Dye-sensitized solar cell (DSSC) is one of the emerging thin-film photovoltaic technologies. Advantages come from the low cost and easier fabrication process. The realistic overall conversion efficiency already made the commercial availability a reality. It is possible the use of natural dyes extracted from plants in DSSC fabrication to substitute synthetic dyes, which requires complex fabrication processes and the use of toxic and scarce materials, like ruthenium. Natural dye-sensitized solar cells (NDSSC) are still in an early stage, with many research groups working hard to overcome efficiency and stability issues. Natural dyes are cheap, highly available, environmentally safe and easy to...
Pedagogia Vivencionista
Do que serão capazes, no futuro, as crianças educadas através da vida? Apenas uma educação voltada para a vivência de experiências reais, em que o aluno decide e aprende através da realização de seus próprios empreendimentos, prepara a criança para os desafios que o futuro lhe trará, ensinando não apenas o elenco básico de disciplinas escolares, mas também os conhecimentos que somente a experiência de vida lhes trará, favorecendo ainda o desenvolvimento de habilidades fundamentais para a formação de um ser humano mais independente, criativo, autoconfiante e feliz.

Adult Education at the Crossroads
Adopting a social action perspective, this book is an assessment of where adult education now stands in the world. It argues that the purposes and rationale of adult education need to be reconceptualised for it to become an effective agent of change.
Chalcogenide Photovoltaics
This first comprehensive description of the most important material properties and device aspects closes the gap between general books on solar cells and journal articles on chalcogenide-based photovoltaics. Written by two very renowned authors with years of practical experience in the field, the book covers II-VI and I-III-VI2 materials as well as energy conversion at heterojunctions. It also discusses the latest semiconductor heterojunction models and presents modern analysis concepts. Thin film technology is explained with an emphasis on current and future techniques for mass production, and the book closes with a compendium of failure analysis in photovoltaic thin film modules. With its overview of the semiconductor physics and technology needed, this practical book is ideal for students, researchers, and manufacturers, as well as for the growing number of engineers and researchers working in companies and institutes on chalcogenide photovoltaics.
Interfacial Engineering in Functional Materials for Dye-Sensitized Solar Cells
Offers an Interdisciplinary approach to the engineering of functional materials for efficient solar cell technology Written by a collection of experts in the field of solar cell technology, this book focuses on the engineering of a variety of functional materials for improving photoanode efficiency of dye-sensitized solar cells (DSSC). The first two chapters describe operation principles of DSSC, charge transfer dynamics, as well as challenges and solutions for improving DSSCs. The remaining chapters focus on interfacial engineering of functional materials at the photoanode surface to create greater output efficiency. Interfacial Engineering in Functional Materials for Dye-Sensitized Solar C...
Photoprotection in Plants
Optical screening of excessive and potentially harmful solar radiation is an important photoprotective mechanism, though it has received much less attention in comparison with other systems preventing photooxidative damage to photoautotrophic organisms. This photoprotection in the form of screening appears to be especially important for juvenile and senescing plants as well as under environmental stresses—i.e. in situations where the efficiency of enzymatic ROS elimination, DNA repair and other ‘classical’ photoprotective systems could be impaired. This book represents an attempt to develop an integral view of optical screening-based photoprotection in microalgae and higher plants. Tow...
Semiconductor Device Physics and Design
Semiconductor Device Physics and Design teaches readers how to approach device design from the point of view of someone who wants to improve devices and can see the opportunity and challenges. It begins with coverage of basic physics concepts, including the physics behind polar heterostructures and strained heterostructures. The book then details the important devices ranging from p-n diodes to bipolar and field effect devices. By relating device design to device performance and then relating device needs to system use the student can see how device design works in the real world.
Semiconductor Fundamentals
This book presents those terms, concepts, equations, and models that are routinely used in describing the operational behavior of solid state devices. The second edition provides many new problems and illustrative examples.
Atom Probe Tomography
Atom Probe Tomography is aimed at beginners and researchers interested in expanding their expertise in this area. It provides the theoretical background and practical information necessary to investigate how materials work using atom probe microscopy techniques, and includes detailed explanations of the fundamentals, the instrumentation, contemporary specimen preparation techniques, and experimental details, as well as an overview of the results that can be obtained. The book emphasizes processes for assessing data quality and the proper implementation of advanced data mining algorithms. For those more experienced in the technique, this book will serve as a single comprehensive source of ind...
