Energy crises and global warming pose serious challenges to researchers in their attempt to develop a sustainable society for the future. Solar energy conversion is a remarkable, clean, and sustainable way to nullify the effects of fossil fuels. The findings of photocatalytic hydrogen production (PCHP) by Fujishima and Honda propose that “water will be the coal for the future”. Hydrogen is a carbon-free clean fuel with a high specific energy of combustion. Titanium oxide (TiO2), graphitic-carbon nitride (g-C3N4) and cadmium sulfide (CdS) are three pillars of water splitting photocatalysts owing to their superior electronic and optical properties. Tremendous research efforts have been made in recent years to fabricate visible or solar-light, active photocatalysts. The significant features of various oxide, sulfide, and carbon based photocatalysts for cost-effective hydrogen production are presented in this Special Issue. The insights of sacrificial agents on the hydrogen production efficiency of catalysts are also presented in this issue.
Democracy harbors within it fundamental tensions between the ideal of giving everyone equal consideration and the reality of having to make legitimate, binding collective decisions. Democracies have granted political rights to more groups of people, but formal rights have not always guaranteed equal consideration or democratic legitimacy. It is Michael Morrell’s argument in this book that empathy plays a crucial role in enabling democratic deliberation to function the way it should. Drawing on empirical studies of empathy, including his own, Morrell offers a “process model of empathy” that incorporates both affect and cognition. He shows how this model can help democratic theorists who emphasize the importance of deliberation answer their critics.
PHOTOREACTORS IN ADVANCED OXIDATION PROCESSES Unique book covering topics related to the evolving photoreactors concepts, design, and application as well as green synthesis of heterogenous photocatalysts which are the key aspects to facilitate the escalation of bench scale works toward industrial/commercial applications. In this book, the editors present the most up-to-date research on Advanced Oxidation Processes (AOPs) to make the argument that AOPs offer an eco-friendly method of wastewater treatment. In addition to an overview of the fundamentals and applications, it provides ample details of the reactive species involved in AOPs as well as reactor design concepts, thus providing readers...
Photocatalysts in Advanced Oxidation Processes for Wastewater Treatment comprehensively covers a range of topics aiming to promote the implementation of photocatalysis at large scale through provision of facile and green methods for catalysts synthesis and elucidation of pollutants degradation mechanisms. This book is divided into two main parts namely “Synthesis of effective photocatalysts” (Part I) and “Mechanisms of the photocatalytic degradation of various pollutants” (Part II). The first part focuses on the exploration of various strategies to synthesize sustainable and effective photocatalysts. The second part of the book provides an insights into the photocatalytic degradation mechanisms and pathways under ultraviolet and visible light irradiation, as well as the challenges faced by this technology and its future prospects.
Every war has refugees; every revolution has exiles. Most of the refugees of the French Revolution mourned the demise of the monarchy. Lessons from America examines an unusual group who did not. Doina Pasca Harsanyi looks at the American experience of a group of French liberal aristocrats, early participants in the French Revolution, who took shelter in Philadelphia during the Reign of Terror. The book traces their path from enlightened salons to revolutionary activism to subsequent exile in America and, finally, back to government posts in France&—illuminating the ways in which the French experiment in democracy was informed by the American experience.
Influential popular philosopher Roman Krznaric argues our brains are wired for social connection: empathy is at the heart of who we are. It's an essential, transforming quality we must develop for the 21st Century. Through encounters with actors, activists, groundbreaking designers, undercover journalists, nurses, bankers and neuroscientists, Krznaric defines a new breed of adventurer. He sets out the six life-enhancing habits of highly empathic people, whose skills enable them to connect with others in extraordinary ways. Empathy has the power to transform relationships, from the personal to the political. Krznaric contends that, as we move on from an age of introspection, empathy will be key to fundamental social change - making this book a manifesto for revolution.
Assessing the grand American evangelical missionary venture to convert the world, this international group of leading scholars reveals how theological imperatives have intersected with worldly imaginaries from the nineteenth century to the present. Countering the stubborn notion that conservative Protestant groups have steadfastly maintained their distance from governmental and economic affairs, these experts show how believers' ambitious investments in missionizing and humanitarianism have connected with worldly matters of empire, the Cold War, foreign policy, and neoliberalism. They show, too, how evangelicals' international activism redefined the content and the boundaries of the movement...
Nanostructured electrode materials have exhibited unrivaled electrochemical properties in creating elite supercapacitors. Morphology Design Paradigm for Supercapacitors presents the latest advances in the improvement of supercapacitors, a result of the incorporation of nanomaterials into the design – from zero-dimensional to three-dimensional, and microporous to mesoporous. The book includes a comprehensive description of capacitive practices at the levels of sub-atomic and nanoscales. These have the ability to enhance device performance for an extensive assortment of potential applications, including consumer electronics, wearable gadgets, hybrid electric vehicles, stationary and industri...
