Synthesis and characterization of carbon nano-structures for methane storage

Natural gas (NG), which contains about 95% methane is currently gaining global acceptance as fuel for combustion engines because it is environmentally friendly and clean, naturally abundant, and cheaper than gasoline or diesel. Upon combustion when compared to gasoline or diesel it emits much less c...
