Nanostructured and advanced materials for applications in sensor, optoelectronic and photovoltaic technology ; Proceedings of the NATO Advanced Study Institute on nanostructured and advanced materials for applications in sensors, optoelectronic and photovoltaic technology ; Sozopol, Bulgaria, 6-17 September 2004
Nanotechnology is an emerging scientific field receiving significant worldwide attention. On a nanometer scale, materials or structures may possess new and unique physical properties. Some of these are now known to the scientific community, but there may well be many properties not yet known to us, rendering it as a fascinating area of research and a suitable subject for a NATO ASI. Yet another aspect of the field is the possibility for creating meta-stable phases with unconventional properties and the ultra-miniaturization of current devices, sensors, and machines. Such nanotechnological and related advanced materials have an extremely wide range of potential applications, viz. nanoscale electronics, sensors, optoelectronics, photonics, nano-biological systems, na- medicine, energy storage systems, etc. This is a wide-ranging subject area and therefore requires the formation of multi-disciplinary teams of physicists, chemists, materials scientists, engineers, molecular biologists, pharmacologists, and others to work together on the synthesis and processing of materials and structures, the understanding of their physical properties, the design and fabrication of devices.
Concentrator Photovoltaics
In fact, photovoltaic conversion of concentrated sunlight insures an efficient and cost-effective sustainable power resource. This book gives an overview of all components. The authors report on significant results related to design, technology, and applications, and also cover the fundamental physics and market considerations.
Lead Markets for Environmental Innovations
Often, the leadership in technological development is accompanied by a leadership in environmental policy. The book provides an analysis of lead markets for innovations such as fuel cells, photovoltaics, and others. Contributions of innovation economics, policy analysis and environmental economics are assessed regarding their potential to explain the leadership of single countries. The book depicts the policy frameworks that are favourable to the creation of such lead markets on the basis of theoretical considerations and case studies. Finally, recommendations for R and D policies, environmental and industrial policies are derived.
Biofuels, Solar and Wind as Renewable Energy Systems : Benefits and Risks
With shortages of fossil energy, especially oil and natural gas, and heavy biomass energy use occurring in both developed and developing countries, a major focus has developed worldwide on renewable energy systems. Renewable energy systems include wind power, biomass, photovoltaics, hydropower, solar thermal, thermal ponds, and biogas. Currently, a heavy focus is on biofuels made from crops, such as corn, sugarcane, and soybeans, for use as renewable energy sources. Wood and crop residues also are being used as fuel. Though it may seem beneficial to use renewable plant materials for biofuel, the use of crop residues and other biomass for biofuels raises many concerns about major environmental problems, including food shortages and serious destruction of vital soil resources.
