Researchers have developed a new process which will greatly simplify the process of sorting plastics in recycling plants. The method enables automated identification of polymers, facilitating rapid separation of plastics for re-use.
An Australian National University (ANU) team has successfully replicated one of the crucial steps in photosynthesis, opening the way for biological systems powered by sunlight which could manufacture hydrogen as a fuel.
Your chairs, synthetic rugs and plastic bags could one day be made out of cocoa, rice and vegetable waste rather than petroleum, scientists are now reporting. The novel process they developed could help the world deal with its agricultural and plastic waste problems.
A cooperation between chemists and biologists resulted in a new method for the very efficient integration of photosynthetic proteins in photovoltaics. Their recent report offers a new immobilization strategy that yields electron transfer rates exceeding for the first time rates observed in natural photosynthesis.
A ew type of solar concentrator that, when placed over a window, creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a flat, clear surface.
In recent years, the number of patent applications for electrochemical energy storage technologies has soared. According to a new study, the largest volume of applications by far is submitted by developers of lithium batteries. The study offers a first differentiated analysis of which energy storage technologies will be viable in the exit from fossil-fuel energy. In this area, European and US companies are falling behind economically, as Asian companies apply for a substantially higher number of patents.
While the powerful solvents known as ionic liquids show great promise for liberating fermentable sugars from lignocellulose and improving the economics of advanced biofuels, an even more promising candidate is on the horizon - bionic liquids.
Microalgae need only sunlight and water for the production of hydrogen. However, in order to make hydrogen production by microalgae economically feasible their efficiency has to be increased by 1-2 orders of magnitude. Researchers now present how an improvement in efficiency can be achieved.
Global installations of tidal stream and wave power are set to grow to 148MW and 21MW respectively by the end of this decade, from almost nothing today, but these are still trifling amounts in the context of the world?s power system.
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.
