In the context of wastewater treatment, Bioelectrochemical Systems (BESs) have gained considerable interest in the past few years, and several BES processes are on the brink of application to this area. This book, written by a large number of world experts in the different sub-topics, describes the different aspects and processes relevant to their development. Bioelectrochemical Systems (BESs) use micro-organisms to catalyze an oxidation and/or reduction reaction at an anodic and cathodic electrode respectively. Briefly, at an anode oxidation of organic and inorganic electron donors can occur. Prime examples of such electron donors are waste organics and sulfides. At the cathode, an electron acceptor such as oxygen or nitrate can be reduced. The anode and the cathode are connected through an electrical circuit. If electrical power is harvested from this circuit, the system is called a Microbial Fuel Cell; if electrical power is invested, the system is called a Microbial Electrolysis Cell. The overall framework of bio-energy and bio-fuels is discussed. A number of chapters discuss the basics – microbiology, microbial ecology, electrochemistry, technology and materials development. The book continues by highlighting the plurality of processes based on BES technology already in existence, going from wastewater based reactors to sediment based bio-batteries. The integration of BESs into existing water or process lines is discussed. Finally, an outlook is provided of how BES will fit within the emerging biorefinery area.

In recent years organic sulfur chemistry has been growing at an even faster pace than the very rapid development in other fields of chemistry. This phenomenal growth is undoubtedly a reflection of industrial and public demands: not only was sulfur recently in overall surplus for the first time in the history of the chemical industry but it has now become a prin cipal environmental hazard in the form of sulfur dioxide, sulfuric acid and hydrogen sulfide. Another reason, discernible in the last fifteen years, has been the desire, on the part of individual chemists and all types of research managers, to move away from the established chemistry of carbon into the less well understood and sometimes virgin chemistries of the other elements which form covalent bonds. As a result of this movement the last decade has seen the development of sulfur chemistry into a well-organized and now much better understood branch of organic chemistry. Enough of the detail has become clear to see mechanistic interrelationships between previously unconnected reactions and with this clarification the whole subject has in tum become systema tized and subdivided. The divalent sulfur chemistry of thiols, monosulfides, disulfides and polysulfides is a large area in itself, much of it devoted to oxidation-reduction and the breakage and formation of sulfur-sulfur bonds, although interesting discoveries are now being made about the reac tivity of certain sulfur-carbon bonds. Of course, this area has its own mas sive biochemical branch involving enzymes and proteins.

Despite more than 200 years of sulfur research the chemistry of elemental sulfur and sulfur-rich compounds is still full of “white spots” which have to be filled in with solid knowledge and reliable data. This situation is parti- larly regrettable since elemental sulfur is one of the most important raw - terials of the chemical industry produced in record-breaking quantities of ca. 35 million tons annually worldwide and mainly used for the production of sulfuric acid. Fortunately, enormous progress has been made during the last 30 years in the understanding of the “yellow element”. As the result of extensive inter- tional research activities sulfur has now become the element with the largest number of allotropes, the element with the largest number of binary oxides, and also the element with the largest number of binary nitrides. Sulfur, a typical non-metal, has been found to become a metal at high pressure and is even superconducting at 10 K under a pressure of 93 GPa and at 17 K at 260 GPa, respectively. This is the highest critical temperature of all chemical elements. Actually, the pressure-temperature phase diagram of sulfur is one of the most complicated of all elements and still needs further investigation.

Organic Sulfur Compounds, Volume I deals with the chemistry of organic sulfur compounds such as disulfides, polysulfides, olefins, acetylenes, and chloroethylenes. Topics covered range from the inorganic acids of sulfur and the thermodynamics of organic sulfur compounds to some applications of isotopic sulfur and the stereochemistry of disulfides and polysulfides. The mechanism of oxidation of thiols to disulfides is also discussed. Comprised of 40 chapters, this volume first considers the precise structures of elemental sulfur in relation to the reactions of sulfur compounds, followed by an analysis of the inorganic acids of sulfur. The reader is then introduced to the thermodynamics of organic sulfur compounds and the bonding characteristics of the sulfur atom, as well as the infrared spectra of organosulfur compounds. Subsequent chapters focus on the ionic scission of the sulfur-sulfur bond; nucleophilic reactions of thiols with acetylene and chloroethylene; reactions of sulfur with olefins; and the chemistry of isothiocyanates. This book should prove useful to advanced students, practitioners, and research workers in the field of organic chemistry.
