Meet the Martian meteorite hunters

Magnified view of the surface of the rock known as “Block Island”, on the surface of Mars. The image was taken by the microscopic imager onboard NASA’s Mars Exploration Rover Opportunity during the 1,963rd Martian day, or sol, of the rover’s mission on Mars (1 August, 2009). The triangular pattern of small ridges seen at … Read more

The next big thing in li-ion battery technology

“Wrapping” anodes in 3d carbon nanosheets. Credit: Korea Maritime and Ocean University Lithium-ion batteries (LIBs), which are a renewable source of energy for electrical devices or electric vehicles, have attracted much attention as the next-generation energy solution. However, the anodes of LIBs in use today have multiple inadequacies, ranging from low ionic electronic conductivity and … Read more

Fully renewable energy feasible for Samoa

Credit: CC0 Public Domain The future of Samoa’s electricity system could go green, a University of Otago study has shown. Pacific Island nations are particularly susceptible to climate change and face high costs and energy security issues from imported fossil fuels. For these reasons many Pacific Island nations have developed ambitious 100 per cent renewable … Read more
