Climate change has become a worldwide concern with the rapid rise of the atmospheric Co2 concentration. To mitigate Co2 emissions, the research and development efforts in Co2 capture and separation both from the stationary sources with high Co2 concentrations e. Much progress has been achieved, especially within the last twenty years. In this perspective, we first briefly review the current status of carbon capture technologies including absorption, adsorption, membrane, biological capture, and cryogenic separation, and compare their advantages and disadvantages. Then, we focus mainly on the recent advances in the absorption, adsorption, and membrane technologies. Even though numerous optimizations in materials and processes have been pursued, implementing a single separation process is still quite energy-intensive or costly.

Preparation and mechanical properties of chitosan/carbon nanotubes composites
Carbon fibers or carbon fibres alternatively CF, graphite fiber or graphite fibre are fibers about 5 to 10 micrometers 0. However, they are relatively expensive when compared with similar fibers, such as glass fiber , basalt fibers , or plastic fibers. To produce a carbon fiber, the carbon atoms are bonded together in crystals that are more or less aligned parallel to the long axis of the fiber as the crystal alignment gives the fiber high strength-to-volume ratio in other words, it is strong for its size. Several thousand carbon fibers are bundled together to form a tow , which may be used by itself or woven into a fabric.
