Diamond-based composites, with their advantages of hardness, high Young's modulus and the like, have demonstrated new and unusual features, such as stability to high temperatures and pressure shocks and a large internal surface that can be controlled to offer customised electrical, magnetic and optical properties, leading to efficient filters, absorbents, sensors and other tools for environmental control and monitoring. The current book covers the synthesis of materials, their characterization and properties, trends in high pressure and high temperature technologies, low pressure technologies, basic principles of DBC material science, and future developments in electronics, optics, industrial tools and components, biotechnology, and medicine. Wide band-gap materials are considered, ranging from molecular clusters, nanophase materials, growth, processing and synthesis. The processing of composite based materials can be classified into six basic methods: in situ growth, high pressure/high temperature catalytic conversion; mix and sinter (c-BN plus metal-ceramic polymer mix); direct sintering; direct polymorphic conversion; shock detonation; and SHS sintering.
Nonproliferation Issues for Weapons of Mass Destruction provides an
understanding of WMD proliferation risks by bridging complex
technical and political issues. The text begins by defining the
world conditions that foster proliferation, followed by an analysis
of characteristics of various classes of WMDs, including nuclear,
biological, and chemical weapons. It then explores the
effectiveness of arms control, discussing current nonproliferation
problems, nonproliferation prior to the fall of the USSR, and
weapons safeguards.
This second volume of Energy Resources and Systems is focused on renewable energy resources. Renewable energy mainly comes from wind, solar, hydropower, geothermal, ocean, bioenergy, ethanol and hydrogen. Each of these energy resources is important and growing. For example, high-head hydroelectric energy is a well established energy resource and already contributes about 20% of the world s electricity. Some countries have significant high-head resources and produce the bulk of their electrical power by this method. However, the bulk of the world s high-head hydroelectric resources have not been exploited, particularly by the underdeveloped countries. Low-head hydroelectric is unexploited and has the potential to be a growth area. Wind energy is the fastest growing of the renewable energy resources for the electricity generation. Solar energy is a popular renewable energy resource. Geothermal energy is viable near volcanic areas. Bioenergy and ethanol have grown in recent years primarily due to changes in public policy meant to encourage its usage. Energy policies stimulated the growth of ethanol, for example, with the unintended side effect of rise in food prices. Hydrogen has been pushed as a transportation fuel. The authors want to provide a comprehensive series of texts on the interlinking of the nature of energy resources, the systems that utilize them, the environmental effects, the socioeconomic impact, the political aspects and governing policies. Volume 1 on Fundamentals and Non Renewable Resources was published in 2009. It blends fundamental concepts with an understanding of the non-renewable resources that dominate today s society. The authors are now working on Volume 3, on nuclear advanced energy resources and nuclear batteries, consists of fusion, space power systems, nuclear energy conversion, nuclear batteries and advanced power, fuel cells and energy storage. Volume 4 will cover environmental effects, remediation and policy. Solutions to providing long term, stable and economical energy is a complex problem, which links social, economical, technical and environmental issues. It is the goal of the four volume Energy Resources and Systems series to tell the whole story and provide the background required by students of energy to understand the complex nature of the problem and the importance of linking social, economical, technical and environmental issues."
Minsk, Belarus was the site of the NATO ARW on Wide Band-Gap electronic Materials May 3 through 6,1994; 143 participants and observers from 15 countries met for the NATO Advanced Research Workshop on Wide Band-Gap Electronic Materials (NATO ARW). The meeting was marked by a remarkable free exchange between east and west on these topics by revealing technical achievements not widely known or available in the west because ofpast political climate or present economic realities in the Newly IndependentStates. The topics ranged from electron doping of diamond, n-type diamond, negative electron affinity ofdiamond, applications of aluminum nitride, doping ofboron nitride, wideband gap electronic applications, to nanophase diamond. Of the many high-lights during the scientific meetings, an energy sub band due to defects in the diamond lattice was described. These defects areresponsible for the light emission from a diamond Light Emitting Diode (LED) which was demonstrated at the NATO ARW. This diamond LED can emitred, green, and blue light. The potential for "high tech" nanostructure electronic devices such as quantum transistors was described which mightsome day revolutionize electronics. The prospectsofaluminum nitride for acusto devices, piezodevices, and electroluminescencedevices were discussed.
In the lifetimes of the authors, the world and especially the United States have received three significant "wake-up calls" on energy production and consumption. The first of these occurred on October 15, 1973 when the Yom Kippur War began with an attack by Syria and Egypt on Israel. The United States and many western countries supported Israel. Because of the western support of Israel, several Arab oil exporting nations imposed an oil embargo on the west. These nations withheld five million barrels of oil per day. Other countries made up about one million barrels of oil per day but the net loss of four million barrels of oil production per day extended through March of 1974. This represented 7% of the free world's (i. e. , excluding the USSR) oil production. In 1972 the price of crude oil was about $3. 00 per barrel and by the end of 1974 the price of oil had risen by a factor of 4 to over $12. 00. This resulted in one of the worst recessions in the post World War II era. As a result, there was a movement in the United States to become energy independent. At that time the United States imported about one third of its oil (about five million barrels per day). After the embargo was lifted, the world chose to ignore the "wake-up call" and went on with business as usual.

Traditionally, resources on terrorism and counterterrorism tend to focus on the social, behavioral, and legal aspects of the subject, with minimal emphasis on the scientific and technological aspects. Taking into account these practical considerations, the second edition of Science and Technology of Terrorism and Counterterrorism discusses the nature of terrorism and the materials used by terrorists. It describes how intelligence professionals and law enforcement personnel can detect and destroy these materials, and how they can deal with terrorist groups. This volume begins by introducing the shift in analysis of terrorist attacks after September 11, 2001 and summarizes selected case studies. It discusses the origin and nature of terrorism and the factors involved in diplomacy. Covering a broad range of topics, the book examines: Aerosol dispersion of toxic materials Bioterrorism and the manufacture, detection, and delivery of biological agents Agricultural terrorism Nuclear terrorism and nuclear weapons systems, threats, and safeguards Chemical terrorism, including manufacture, detection, delivery, and decontamination Cyber-terrorism Personal protective equipment The role of government at federal, state, and local levels The role of international agencies and their resources, capabilities, and responsibilities The National Infrastructure Protection Plan As terrorist activities increase globally, it is critical that those charged with protecting the public understand the myriad of ways in which terrorists operate. While we cannot predict where, when, and how terrorists will strike, our vigilance in staying abreast of the terrorist threat is the only way to have a fighting chance against those who seek to destroy our world.
