The present monograph attempts to unify these diverse and exciting new developments within a common framework. First, the physical principles underlying heterogenous electron-transfer processes are outlined in a concise way and are compared to the homogeneous counterpart. This analysis includes the notion of the Fermi level in liquids and solids as well as the distribution of electronic energy levels in solids and liquids. A comparison is made between the salient kinetic features of homogeneous and heterogeneous electron transfer reactions. This establishes the basis for the subsequent treatment of the transduction of excitation energy and photo-initiated electron transfer in organized molecular assemblies, such as micelles, vesicles and monolayers. Transmembrane redox processes are critically reviewed. Particular attention is given to semiconductor electrodes and particles. This includes a discussion of quantum size effects, the nature of space charge layers as well as surface states and the dynamics of charge carrier-induced redox reactions at the semiconductor solution interface. These processes are of fundamental importance in such diverse fields as photochromism, electrochromic displays, electroreprography and photography, information storage, photocatalysis, photodegradation of paints, and solar energy conversion.

In this book, expert authors describe advanced solar photon conversion approaches that promise highly efficient photovoltaic and photoelectrochemical cells with sophisticated architectures on the one hand, and plastic photovoltaic coatings that are inexpensive enough to be disposable on the other. Their leitmotifs include light-induced exciton generation, junction architectures that lead to efficient exciton dissociation, and charge collection by percolation through mesoscale phases. Photocatalysis is closely related to photoelectrochemistry, and the fundamentals of both disciplines are covered in this volume.

The book collects the lectures and the status reports delivered during the "Eighth International Conference on Photochemical Conversion and Storage of Solar Energy", IPS-8, held in Palermo (Italy) from 15th to 20th of July 1990. As usual, the main theme of the Conference was that of making the point about the trends and the developments of the studies related to the photochemical exploitation of solar energy and also to report the main lines of potential applications. Therefore the contributions reflect this point; they vary from those reporting basic and fundamental theories to those reporting cases of possible applications. For the sake of following the logical line which links each other the various contributions, we report the six areas in which the main theme of the conference was devided: (a) Electron and energy transfer in homogeneous and heterogeneous systems; (b) Photosynthesis: organized assemblies and biomimetic systems; (c) Photoelectrochemistry; (d) Photocatalysis: homogeneous and heterogeneous regime; (e) Environment: photochemical and photocatalytic processes; (f) Solar energy materials and photochemical engineering. It remains now to thank persons and institutions which made possible the organization of the Conference. The persons to thank are all the members of the International and National Organizing Committees and in particular Prof. A.Sclafani and Dr. L.Palmisano whose efforts were essential for the success of the Conference.

Volume 23 of Reviews in Mineralogy and accompanying MSA short course covers chemical reactions that take place at mineral-water interfaces. We believe that this book describes most of the important concepts and contributions that have driven mineral-water interface geochemistry to its present state. We begin in Chapter 1 with examples of the global importance of mineral-water interface reactions and a brief review of the contents of the entire book. Thereafter, we have divided the book into four sections, including atomistic approaches (Chapters 2- 3), adsorption (Chapters 4-8), precipitation and dissolution (Chapters 9-11), and oxidation-reduction reactions (Chapters 11-14).

In this book, we have summarized recent progresses due to novel nanomaterials for sustainable water resources. Book provides a summary of the state of the art knowledge to scientists, engineers and policy makers, about recent developments due to nanotechnology for sustainable water resources arena. The advances in sustainable water resources technologies in the context of modern society’s interests will be considered preferably which allow to identify grand challenges and directions for future research. The book contributors have been selected from all over the world and the essential functions of the nanotechnologies have presented rather than their anticipated applications. Moreover, up to date knowledge on economy, toxicity and regulation related to nanotechnology are presented in detail. In the end, role of nanotechnology for green and sustainable future has also been briefly debated.

Over the past few decades, mankind has observed an unprecedented and remarkable growth in industry, resulting in a more prosperous lifestyle for peoples of many countries. In developing countries, however, explosive industrial growth is just now beginning to raise the living standards of the people. Most industries, especially in these developing countries, are still powered by the burning of fossil fuels; con- quently, a lack of clean energy resources has caused environmental pollution on an unprecedented large and global scale. Toxic wastes have been relentlessly released into the air and water leading to serious and devastating environmental and health problems while endangering the planet and life itself with the effects of global warming. To address these urgent environmental issues, new catalytic and photocatalytic processes as well as open-atmospheric systems are presently being developed that can operate at room temperature while being totally clean and ef?cient and thus environmentally harmonious. Essential to technologies harnessing the abundant solar energy that reaches the earth are the highly functional photocatalytic proce- es that can utilize not only UV light, but also visible light.

Alternative Fuels and the Environment evaluates the timely issue of renewable, alternative resources to fossil fuels and nuclear energy, such as solar, anemoelectric, hydroelectric, and geothermal energy. These alternative power sources not only have the advantage of being renewable, but they are also economically attractive and have minimal adverse environmental impact, such as the waste emission of SO2, NOx, or greenhouse gases. This book analyzes the harnessing of the sun's energy by photochemical reactions, artificial photosynthesis, and photovoltaic electric power generation. It further discusses how hydrogen as fuel is produced by solar photoelectrolysis of water and how wind turbines generate electricity, while ocean thermal energy produces electric power and fresh water. Geothermal energy and hydroelectric power are also renewable sources of electricity. Biofuels and biomass are useful as energy sources, and surplus land is usable for woody, herbaceous, high-yield energy crop production. The book also investigates reformulated gasoline with oxygenated fuels, such as ethanol or methanol.

Comprehensive Coordination Chemistry II (CCC II) is the sequel to what has become a classic in the field, Comprehensive Coordination Chemistry, published in 1987. CCC II builds on the first and surveys new developments authoritatively in over 200 newly comissioned chapters, with an emphasis on current trends in biology, materials science and other areas of contemporary scientific interest.
