Electrokinetic and Colloid Transport Phenomena

by Jacob H. Masliyah Subir Bhattacharjee

A new, definitive perspective of electrokinetic and colloid transport processes Responding to renewed interest in the subject of electrokinetics, Electrokinetic and Colloid Transport Phenomena is a timely overview of the latest research and applications in this field for both the beginner and the professional. An outgrowth of an earlier text (by coauthor Jacob Masliyah), this self-contained reference provides an up-to-date summary of the literature on electrokinetic and colloid transport phenomena as well as direct pedagogical insight into the development of the subject over the past several decades. A distinct departure from standard colloid science monographs, Electrokinetic and Colloid Transport Phenomena presents the most salient features of the theory in a simple and direct manner, allowing the book to serve as a stepping-stone for further learning and study. In addition, the book uniquely discusses numerical simulation of electrokinetic problems and demonstrates the use of commercial finite element software for solving these multiphysics problems. Among the topics covered are: * Mathematical preliminaries * Colloidal systems * Electrostatics and application of electrostatics * Electric double layer * Electroosmosis and streaming potential * Electrophoresis and sedimentation potential * London-Van der Waals forces and the DLVO theory * Coagulation and colloid deposition * Numerical simulation of electrokinetic phenomena * Applications of electrokinetic phenomena Because this thorough reference does not require advanced mathematical knowledge, it enables a graduate or a senior undergraduate student approaching the subject for the first time to easily interpret the theories. On the other hand, the application of relevant mathematical principles and the worked examples are extremely useful to established researchers and professionals involved in a wide range of areas, including electroosmosis, streaming potential, electrophoretic separations, industrial practices involving colloids and complex fluids, environmental remediation, suspensions, and microfluidic systems.

Electrokinetics Across Disciplines and Continents: New Strategies for Sustainable Development

by Alexandra B. Ribeiro Eduardo P. Mateus Nazaré Couto

The socio-economic activities due to world development are promoting increasing pressures on land, creating competition and conflicts, resulting in suboptimal use of resources. Integrated planning and management of land resources is a top subject of Agenda 21 (managed by FAO), which deals with the cross-sectoral aspects of decision-making for the sustainable use and development of natural resources. This is essential for life-support systems and its productive capacity. In this context, there is a need to find new strategies for sustainable development that links social and economic progress with environmental protection and enhancement. Electrokinetic transport processes (EK) uses a low-level direct current as the “cleaning agent”. EK has been applied to the remediation of polluted soils and other contaminated matrices. It also shows a great potential to be used in different fields, as in saline soil restoration, nutrients recovery from wastes or repair and maintenance of building structures. EK may be an integrated approach for new strategies aiming at sustainable development and to support waste strategies, with worldwide interest. EK can also be coupled with phytoremediation and integrated with nanotechnology, enlarging the scope of its application. The conciliation of the EK in the recovery of secondary resources, remediation and conservation is a multidisciplinary novel approach that opens new technical possibilities for waste minimization, through upgrading of particulate waste products and the recovery of secondary resources for industrial, agricultural or social use.

Electrokinetics for Petroleum and Environmental Engineers

by G. V. Chilingar Mohammed Haroun

Electrokinetics is a term applied to a group of physicochemical phenomena involving the transport of charges, action of charged particles, effects of applied electric potential and fluid transport in various porous media to allow for a desired migration or flow to be achieved. These phenomena include electrokinetics, electroosmosis, ion migration, electrophoresis, streaming potential and electroviscosity. These phenomena are closely related and all contribute to the transport and migration of different ionic species and chemicals in porous media. The physicochemical and electrochemical properties of a porous medium and the pore fluid, and the magnitudes of the applied electrical potential all impact the direction and velocity of the fluid flow. Also, an electrical potential is generated upon the forced passage of fluid carrying charged particles through a porous medium. The use of electrokinetics in the field of petroleum and environmental engineering was groundbreaking when George Chilingar pioneered its use decades ago, but it has only been in recent years that its full potential has been studied. This is the first volume of its kind ever written, offering the petroleum or environmental engineer a practical “how to” book on using electrokinetics for more efficient and better oil recovery and recovery from difficult reservoirs. This groundbreaking volume is a must-have for any petroleum engineer working in the field, and for students and faculty in petroleum engineering departments worldwide.

Electroluminescence: Proceedings of the Fourth International Workshop Tottori, Japan, October 11–14, 1988 (Springer Proceedings in Physics #38)

by Shigeo Shionoya Hiroshi Kobayashi

The Fourth International Workshop on Electroluminescence (EL-88) was held at the Hotel Holiday, Tottori, Japan, October 11-14, 1988. This workshop was sponsored by the 125 Research Committee on Mutual Conversion between Light and Electricity, Japan Society for the Promotion of Science, in cooperation with SID (Society for Infonnation Display) Japan Chapter, Tottori Prefecture, the Tot­ tori Industrial Technology Association, and the Foundation for Advancement of International Science (FAIS). The workshop EL-88 was a continuation of the series of international work­ shops held successively at Liege (Belgium) in 1980, Bad Stuer (DDR) in 1983, and at Wann Springs (Oregon, USA) in 1986. It brought together scientists and engi­ neers from universities and industry who shared a common interest in discussing electroluminescence and related topics. The number of participants reached 253; 49 from abroad (10 countries) and 204 from Japan. This is almost four times as many as in the previous workshop in 1986, reflecting the recent rapid development and progress of electroluminescence research.
