This book presents experimental and theoretical results on extremely powerful plasma generators. It addresses pulsed electrical mega-ampere arcs and the mechanisms of energy transfer from the arc into hydrogen, helium and air under pressures up to 250 MPa and currents up to 2 MA. Extreme plasma parameters and increased energy density in the arc were achieved. It was found experimentally that increasing the initial gas pressure to hundreds of MPa leads to improved arc stability, high efficiency of energy transfer from arc to gas, and plasma enthalpy growth. The data obtained data provides the basis for the development of electrophysical devices with high energy density, e.g. high intensity sources for visible, UV and X-ray irradiation for laser pumping, generators of high enthalpy plasma jets, and plasma chemical reactors.

This proceedings volume comprises the invited plenary lectures, contributed and poster papers presented at a symposium organised to mark the successful inauguration of the world's first commercial plant for production of gasoline from natural gas, based on the Mobil methanol-to-gasoline process. The objectives of the Symposium were to present both fundamental research and engineering aspects of the development and commercialization of gas-to-gasoline processes. These include steam reforming, methanol synthesis and methanol-to-gasoline. Possible alternative processes e.g. MOGD, Fischer-Tropsch synthesis of hydrocarbons, and the direct conversion of methane to higher hydrocarbons were also considered.The papers in this volume provide a valuable and extremely wide-ranging overview of current research into the various options for natural gas conversion, giving a detailed description of the gas-to-gasoline process and plant. Together, they represent a unique combination of fundamental surface chemistry catalyst characterization, reaction chemistry and engineering scale-up and commercialization.

Plasma methods that effectively combine ultraviolet radiation, active chemicals, and high electric fields offer an alternative to conventional water treatment methods. However, knowledge of the electric breakdown of liquids has not kept pace with this increasing interest, mostly due to the complexity of phenomena related to the plasma breakdown process. Plasma Discharge in Liquid: Water Treatment and Applications provides engineers and scientists with a fundamental understanding of the physical and chemical phenomena associated with plasma discharges in liquids, particularly in water. It also examines state-of-the-art plasma-assisted water treatment technologies. The Physics & Applications of Underwater Plasma Discharges The first part of the book describes the physical mechanism of pulsed electric breakdown in water and other liquids. It looks at how plasma is generated in liquids and discusses the electronic and bubble mechanism theories for how the electric discharge in liquid is initiated. The second part of the book focuses on various water treatment applications, including: Decontamination of volatile organic compounds and remediation of contaminated water Microorganism sterilization and other biological applications Cooling water treatment Drawing extensively on recent research, this one-stop reference combines the physics and applications of electric breakdown in liquids in a single volume. It offers a valuable resource for scientists, engineers, and students interested in the topic of plasmas in liquids.

This is an up-to-date review of studies in the physics of pulsed electrical discharges in a vacuum. It gives the reader detailed information on the processes occurring at electrodes and in vacuum gaps and on the mechanisms of discharge initiation and development. Modern techniques and equipment are described in detail. Their high temporal and spatial resolution may be used to solve a number of problems concerning the short-term and microscopic aspects of discharges. A summary is given of a great deal of experimental data on the kinetics of vacuum breakdown. The authors used these results to identify a series of steps in the vacuum breakdown phenomenon. They were the first to discover and describe the explosive electron emission phenomenon and to show its fundamental role in the spark and the arc stages of a discharge. The information in this book may encourage the reader to design new experiments. The results presented may be applied to solve specific research or engineering problems.

Glow Discharge Optical Emission Spectrometry (GD-OES) is rapidly becoming one of the most important techniques for the direct analysis of solids. This, the first book entirely devoted to the subject, represents the combined contributions of over 30 specialists from around the world. All contributors are active in the field and recognised internationally for their expertise and knowledge in GD-OES. The book begins with an introductory overview of the subjects, deals with the design of the instrument, its operation and analytical methods and describes in detail the complex plasma processes which occur inside the glow discharge source. The second part of the book is more practically orientated, showing the full range of uses for GD-OES from the bulk analysis of virtually any solid material to depth profiling within the first tens of micrometres of a variety of surfaces and coatings. Glow Discharge Optical Emission Spectrometry is intended for a wide audience of scientists, engineers and postgraduate students and will be a valuable and challenging reference work for both experienced users of the technique and newcomers alike.

Acid rain, global warming, ozone depletion, and smog are preeminent environmental problems facing the world today. Non-thermal plasma techniques offer an innovative approach to the solution of some of these problems. There are many types of non-thermal plasma devices that have been developed for environmental applications. The potential of these devices for the destruction of pollutants or toxic molecules has already been demonstrated in many contexts, such as nitrogen oxides (NOX) and sulfur dioxide (SO2) in flue gases, heavy metals and volatile organic compounds (VOCs) in industrial effluents, and chemical agents such as nerve gases. This book contains a comprehensive account of the latest developments in non-thermal plasma devices and their applications to the disposal of a wide variety of gaseous pollutants.
