Soil carbon relations : an overview
Soils are localized between base rock, atmosphere and vegetation, and represent a home for numerous organisms and the place of countless biogeochemical transformation and transfer processes. In addition, soils store many substances that are essential to maintain human life and ecosystem processes. Therefore, soils have been a research focus for more than a century and soil science has deep conn...
متن کاملAn Overview of Carbon Transactions
This report provides selected background information to the current portfolio of carbon transactions. The study has a special focus on an analysis of the JI and CDM projects that have been submitted in this early stage of the development of a market in CO 2 credits. It aims at providing insight in the project portfolio with regard to technology and geographical distribution. With the usual disc...
متن کاملCarbon nanotube composites
Carbon nanotubes are molecular-scale tubes of graphitic carbon with outstanding properties. They are among the stiffest and strongest fibres known, with Young’s moduli as high as 1 TPa and tensile strengths of up to 63 GPa. They also have remarkable electronic properties and can be metallic or semiconducting depending on their structure and diameter. There is currently great interest in exploit...
متن کاملCarbon Nanotube Polymer Composites
Figure2 While there are limitless applications for these materials, we are interested in radiation shielding and radiation resistant materials for use in the space industry. Initially, we focused on optically transparent single wall nanotoube (SWNT) polymer composites (2-5). Three different in situ polymerization/sonication methods, heat, light and gamma radiation, were used to produce poly (me...
متن کاملCarbon Fiber Reinforced Bismaleimide Composites
Bismaleimide (BMI) resins are developed very rapidly due to the demands of the defense and aerospace industries. They are cross-linked polymers which process like epoxy resins but have an upper use temperature of 230°C, compared to the epoxy upper use temperature of 175°C. Also due to the available intrinsic properties of BMI resins such as higher thermal stability and lower toxicity than those...
