This issue of ECS Transactions honors Professor Jiri (Art) Janata for his 35 years of contribution to the development of chemical sensors. It focuses on all aspects of chemical sensor technology including organic semiconductor devices, sensing materials, micro and nanomachining, fabrication processes, packaging, and the application of these structures and processes to the miniaturization of chemical sensors, biosensors, miniature chemical analysis systems and other devices and methods for chemical analysis.
Apart from a few articles, no comprehensive study has been written about the learned men and women in America with Czechoslovak roots. That’s what this compendium is all about, with the focus on immigration from the period of mass migration and beyond, irrespective whether they were born in their European ancestral homes or whether they have descended from them. Czech and Slovak immigrants, including Bohemian Jews, have brought to the New World their talents, their ingenuity, their technical skills, their scientific knowhow, and their humanistic and spiritual upbringing, reflecting upon the richness of their culture and traditions, developed throughout centuries in their ancestral home. Th...
The security of the U.S. commercial aviation system has been a growing concern since the 1970's when the hijacking of aircraft became a serious problem. Over that period, federal aviation officials have been searching for more effective ways for non-invasive screening of passengers, luggage, and cargo to detect concealed explosives and weapons. To assist in this effort, the Transportation Security Administration (TSA) asked the NRC for a study of emerging screening technologies. This report-the third of four-focuses on currently maturing millimeter-wavelength/terahertz imaging and spectroscopy technologies that offer promise in meeting aviation security requirements. The report provides a description of the basic operation of these imaging systems, an assessment of their component technologies, an analysis of various system concepts, and an implementation strategy for deployment of millimeter-wavelength/terahertz technology screening systems.
Radioactive wastes resulting from over 40 years of production of nuclear weapons in the U. S. are currently stored in 273 underground tanks at the U. S. Department of Energy Hanford site, Idaho National Engineering and Environmental Laboratory, Oak Ridge Reservation, and Savannah River site. Combined, tanks at these sjtes contain approximately 94,000,000 gallons of waste in a variety of forms including liquid, concrete-like salt cake, and various sludges. More than 730,000,000 curies of several radioactive isotopes are present in the underground tanks. Certainly, one of the greatest challenges facing the U. S. Department of Energy is how to characterize, retrieve, treat, and immobilize the g...
In response to the demands of contemporary solid material analysis-greater powers of detection, speed, depth, and precision-glow devices are receiving increased attention by specialists. This volume covers fundamental plasma processes, laser-based methods, thin film analysis, and many other processes to provide the researcher with an extensive technical reference of these devices.
Electroanalytical chemists and others are concerned not only with the application of new and classical techniques to analytical problems, but also with the fundamental theoretical principles upon which these techniques are based. With the advent of nanotechnology and the drive to create sustainable eco-friendly products, electroanalytical technique
This book, also based on a workshop, assesses the current state of chemistry and chemical engineering at the interface with novel and existing forms of energy and transportation systems. The book also identifies challenges for the chemical sciences in helping to meet the increased demand for more energy, and opportunities for research in energy technologies and in the development of transportation vehicles.
Although good devices exist for presenting visual and auditory sensations, there has yet to be a device for presenting olfactory stimulus. Nevertheless, the area for smell presentation continues to evolve and smell presentation in multimedia is not unlikely in the future. Human Olfactory Displays and Interfaces: Odor Sensing and Presentation provides the opportunity to learn about olfactory displays and its odor reproduction. Covering the fundamental and latest research of sensors and sensing systems as well as presentation technique, this book is vital for researchers, students, and practitioners gaining knowledge in the fields of consumer electronics, communications, virtual realities, electronic instruments, and more.
Historically, most terrorist attacks on civilian targets have involved the use of firearms or explosives, and current defensive strategies are aimed at preventing attacks perpetrated by such means. However, the use of the nerve agent sarin in 1995 to attack the Tokyo subway system, the use of the U.S. mail in 2001 to distribute letters containing anthrax spores, and the discovery in 2004 of the biological toxin ricin in U.S. Senate Office Buildings in Washington, D.C., demonstrate that chemical and biological agents have been added to terrorists' arsenals. Attacks involving chemical/biological agents are of great concern, not only because of the potential for mass casualties but also because...
