Morphology Change and Structural ‎Evaluation of Carbon Nanostructures

   In this study, the change of porosity and roughness of carbon nanostructures, including fullerenes, carbon nanotubes and graphene was investigated according to oxidation process. The effect of oxidation was more sensible on smoother surface of nanostructures. Oxidation increases surface roughness of graphene up to 5.2% and porosity up to 35.2%. While, roughness of hummers graphene is 13....

Carbon Dioxide Fertilisation and Climate Change Policy

Hybrid cars now, fuel cell cars later.

We compare the energy efficiency of hybrid and fuel cell vehicles as well as conventional internal combustion engines. Our analysis indicates that fuel cell vehicles using hydrogen from fossil fuels offer no significant energy efficiency advantage over hybrid vehicles operating in an urban drive cycle. We conclude that priority should be placed on hybrid vehicles by industry and government.

Climate change and carbon dioxide: an introduction.

Since the dawn of history, human beings have had the ability, superior to all other living beings, to exploit the Earth’s environment to their own immediate advantage. For most of human history the consequences were only of local or regional significance. Over the past century, however, the rapid rise in population and the increasing intensity and scale of human enterprises have made it possibl...

Cleaner Cars and Fuels

Advances in vehicle design and fuel quality mean cars can be made cleaner and more efficient. Lower emissions of carbon monoxide (CO), nitrogen oxides (NOx), sulphur dioxide (SO2), particles (including the fine dust and soot PM10) and hydrocarbons (HCs) also known as volatile organic compounds (VOCs) will lead to better urban air quality and less summertime smog. Lower emissions of carbon dioxi...
