Book Description
This volume contains articles from leading analysts and researchers on sustainable transportation, who provide critical reflections on how automobile-related climate policies have evolved up to now in Europe and around the world, in view of the widely recognized need to substantially curb global emissions of greenhouse gases in the coming decades. Authors describe the policies which have been most effective, outline their economic and social implications, present success stories while critically reviewing less successful examples, and suggest strategies to decarbonize passenger transportation on a global scale.

Book Description
In a steady-state tokamak, impurity production and transport from plasma facing components will have to be controlled. Recent results from several divertor tokamaks suggest the importance of chemical sputtering as an impurity production mechanism. However, since impurity production is minimized in high recycling divertor configurations, the quantitative characterization of impurity generation is more difficult than in the high heat flux environment of a limiter configuration. A quantitative study of the role of temperature dependent sputtering mechanisms on the outboard limiter in Tore Supra was performed. The methane flux proved to be significantly reduced above surface temperatures of 1,100 C and negligible above 1,300 C. The peak in the methane yield as a function of surface temperature is consistent with lab results. It was determined that chemical sputtering (early in the shot) had a small, to negligible, impact on the C flux; while RES (late in the shot) had a strong impact on the C flux. However, from the Z{sub eff} measurements, it was concluded that neither process contributed to the core carbon content.

Book Description
This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources - bioenergy, solar, geothermal, hydropower, ocean and wind energy - as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies, and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector, and academic researchers.

Book Description
Carbon is unique in the range of structures and properties that are displayed by its material forms. The bonds in diamond, within the plane ofgraphite and in the fullerene molecules, C , are the strongest covalent bonds possible. This strong covalent bonding 60 leads to some exceptional intrinsic properties, examples ofwhich are: the greatest Young's modulus (in diamond, within the graphite plane and in single walled nanotubes) the highest room temperature thermal conductivity (in diamond and within the graphite plane) high hole mobility in doped diamond exceptional thermal stability ofthe structure in graphite It is because of the extreme thermal stability that such a wide range of materials is available. Atomic mobilities are low at all but the highest temperatures. Sintering, melting and casting ofcarbon are not feasible processing operations and carbon/graphite components are exclusively produced from the pyrolytic decomposition of organic precursors. The vast majority of engineering carbons have Sp2 type bonding and are related in some way to the structure of graphite. In the c-direction the bonding in graphite is of van der Waals character with the result that graphite is highly anisotropic in its properties and is probably unique in showing both the highest and lowest bond strengths in different directions in the same crystal.

Book Description
Proceedings of the Sixteenth International Conference, formerly called the International Conference on Plasma Physics and Controlled Nuclear Fusion Research, Montreal, 7-11 October 1996. The papers presented reflect the excellent progress achieved since the last conference in Seville 1994. Among many other achievements, the Tokamak Fusion Test Reactor has produced over 10 MW of fusion power, the JT-60U experiment has demonstrated plasma conditions equivalent to breakeven, the reversed shear mode has been demonstrated, low aspect ratio tokamaks have produced promising results and plans have been drawn up for powerful new inertial confinement fusion experiments.
