Kerosine jet engines can now run on biofuel

Increased in oil prices have provided new incentives to develop alternative fuel sources for jet engines. Whilst the use of biofuels in jet engines is not new, recent technological advances have meant that biofuel blends can be used without any … Continue reading

Nano-technology improves energy storage

The nanocable, produced with techniques pioneered in the nascent graphene research  field, could be used to build next-generation energy-storage systems. A recent study reports that the capacity of the nanocable is at least 10 times greater than what would be … Continue reading

The magnetic soap that cleans up oil spills

Bristol University has developed a soap that could be used to treat oil spills in the future, using a unique magnetic property. The soap (composed of iron rich salts) dissolves in water, and responds to a magnetic field when placed … Continue reading

The metal sponge that captures CO2

CO2 emissions from industry make up 40% of total CO2 emissions worldwide. Since 1990, improvements in energy intensity have been more than offset by increased total production, such that energy consumption and CO2 emissions have continued to rise dramatically and … Continue reading

Smog-eating paint

A new paint has been created which scientists think could remove 20% of polluting nitrogen in major cities. The technology, called Boysen KNOxOUT, reacts with light and water vapour to filter out nitrogen oxides in the air. Each square metre … Continue reading

Good vibrations: turning sound into energy

Materials scientists at the University of Wisconsin-Madison have developed a technology that harnesses noise or random vibrations in the atmosphere, and uses them to transform water into energy. The vibrations flex two nanocrystals (zinc oxide and barium titanate) placed in … Continue reading
