The information revolution of the twentieth century was brought about by microelectronics based on a simple and common material, silicon. Although silicon will continue to be of central importance in the next century, carbon, silicon's upstairs neighbor in the periodic table, will also be of great impor tance in future technology. Carbon has more flexible bonding and hence has various unique physical, chemical and biological properties. It has two types of bonding, sp3 and sp2, in diamond and graphite, respectively. The existence of the latter, "7r-electron bonding" , is responsible for carbon's versatile tal ents. Those materials having extended 7r-electron clouds are called '7r-electron materials'. They include graphite, carbon nanotubes, fullerenes and various carbonaceous materials. They may be called "supercarbon" because of their fabulous multiformity and versatile properties. This volume is a status report on the synthesis, properties and appli cations of 7r-electron materials, representing an updated proceedings of the International Workshop on 7r-Electron Materials held at the Northwestern University,'Evanston, Illinois, USA, August 13-14,1996. The Workshop was organized jointly by the Japan Science and Technology Corporation (JST) and the Materials Research Center at the Northwestern University (NWU) in order to provide an opportunity for scientists and engineers to meet and dis cuss the latest advances in this field and in commemoration of the Yoshimura 7r-Electron Materials Project, one of Japan's national projects in the JST's ERATO (Exploratory Research for Advanced Technology) program.
Ultrasonic irradiation and the associated sonochemical and sonophysical effects are complementary techniques for driving more efficient chemical reactions and yields. Sonochemistry—the chemical effects and applications of ultrasonic waves—and sustainable (green) chemistry both aim to use less hazardous chemicals and solvents, reduce energy consumption, and increase product selectivity. A comprehensive collection of knowledge, Handbook on Applications of Ultrasound covers the most relevant aspects linked to and linking green chemistry practices to environmental sustainability through the uses and applications of ultrasound-mediated and ultrasound-assisted biological, biochemical, chemical, and physical processes. Chapters are presented in the areas of: Medical applications Drug and gene delivery Nanotechnology Food technology Synthetic applications and organic chemistry Anaerobic digestion Environmental contaminants degradation Polymer chemistry Industrial syntheses and processes Reactor design Electrochemical systems Combined ultrasound−microwave technologies While the concepts of sonochemistry have been known for more than 80 years, in-depth understanding of this phenomenon continues to evolve. Through a review of the current status of chemical and physical science and engineering in developing more environmentally friendly and less toxic synthetic processes, this book highlights many existing applications and the enormous potential of ultrasound technology to upgrade present industrial, agricultural, and environmental processes.
Surfactant research explores the forces responsible for surfactant assembly and the critical industrial, medical, and personal applications, including viscosity control, microelectronics, drug stabilization, drug delivery, cosmetics, enhanced oil recovery, and foods. Surfactant Science and Technology: Retrospects and Prospects, "a Festschrift in ho
In the time since the second edition of The ACS Style Guide was published, the rapid growth of electronic communication has dramatically changed the scientific, technical, and medical (STM) publication world. This dynamic mode of dissemination is enabling scientists, engineers, and medicalpractitioners all over the world to obtain and transmit information quickly and easily. An essential constant in this changing environment is the requirement that information remain accurate, clear, unambiguous, and ethically sound.This extensive revision of The ACS Style Guide thoroughly examines electronic tools now available to assist STM writers in preparing manuscripts and communicating with publishers. Valuable updates include discussions of markup languages, citation of electronic sources, online submission ofmanuscripts, and preparation of figures, tables, and structures. In keeping current with the changing environment, this edition also contains references to many resources on the internet.With this wealth of new information, The ACS Style Guide's Third Edition continues its long tradition of providing invaluable insight on ethics in scientific communication, the editorial process, copyright, conventions in chemistry, grammar, punctuation, spelling, and writing style for any STMauthor, reviewer, or editor. The Third Edition is the definitive source for all information needed to write, review, submit, and edit scholarly and scientific manuscripts.
