Sustainable green alternatives to fertilisers could boost food and energy security

Scientists are looking at formulating sustainable fertilisers from renewable energy waste. This new area of research aims to produce a sustainable, environmentally-friendlier source of soil conditioner and crop fertiliser that could also reduce costs to farmers and potentially, with wide-spread take-up, help to slow down rising food prices.

Stinky gases emanating from landfills could transform into clean energy

A new technique transforming stinky, air-polluting landfill gas could produce the sweet smell of success as it leads to development of a fuel cell generating clean electricity for homes, offices and hospitals, researchers say. The advance would convert methane gas into hydrogen, an efficient, clean form of energy.

Chemists develop MRI technique for peeking inside supercapacitors

Researchers have developed a method for examining the inner workings of battery-like devices called supercapacitors, which can be charged up extremely quickly and can deliver high electrical power. Their technique, based on magnetic resonance imaging (MRI), establishes a means for monitoring and potentially enhancing the performance of such devices.
