nanocrystalline complex oxides have been synthesized by combination of sol–gel auto combustion and ultrasonic irradiation techniques using copper nitrate, zinc nitrate as metallic nitrates and glycine, urea and thiourea as fuels. sol-gel combustion (combination of the chemical sol–gel process and the combustion process) as a proper synthesized technique is used to synthesize zno/cuo nanocomposi...

The article explains the differences between synthetic fuels of first and second generation. potential e-fuels to reduce GHG emissions was indicated. application requirements that need meet in order be used for powering internal combustion engines have been described. possibility using as "drop-in" fuels, blends with conventional petroleum-derived well by themselves discussed. E-fuels developed...

This Editorial introduces a special issue from the 20th International Symposium on Alcohol Fuels (ISAF 2013) on alcohol fuels enabling sustainable future development.

The fast receding concentration of fossil fuels and the mounting global demand of energy has necessitated the production of alternate fuels to replace the conventional fossil fuels so as to counter the increased deposition of greenhouse gasses in the atmosphere, which has led to considerable climatic changes. These changes could result in catastrophic repercussions in the near future, including...
