Rechargeable zinc-air batteries zone in on brother lithium

A researcher holds up a rechargeable zinc-air battery (Credit: University of Sydney) Zinc-air batteries are an enticing prospect thanks to their high energy density and the fact they’re made with some of the most common materials on Earth. Unfortunately, those advantages are countered by how difficult it is to recharge these cells. Now, a team at […]

Scientists Discover New Process Converting Waste Heat Into Usable Electricity

This new material could allow power plants to recycle their waste heat and improve their efficiency. A group of researchers have developed a new material that can be used to turn waste heat into electricity. This technology could allow power plants to recycle their waste heat and save money, while reducing our fossil fuel consumption […]

HOW THIS NEW PERFECT BLUE PIGMENT COLOUR CAN MAKE YOUR HOME COOLER

The near perfect blue pigment was an accidental discovery for Oregon State University scientists, its superhero qualities make it ideal for roofing. Photo: Oregon State University Scientists at Oregon State University have accidently stumbled upon a superhero blue hue with amazing qualities. Lead scientist Mas Subramanian, discovered the colour in 2009 after mixing manganese oxide (a black […]

Scientists Use Silver to Make Lights Shine Brightly

Tue, 06/07/2016 – 9:38am by University of Queen Mary London The toxic and expensive phosphors used widely in fluorescent lighting could be eliminated thanks to a new study conducted by a materials scientist at Queen Mary University of London (QMUL). Writing in the journal Nature Materials, the international group of scientists modified a mineral called zeolite, […]

Metamaterial paves way for thermophotovoltaic cells that generate electricity in the dark

Dr Sergey Kruk demonstrates a prototype metamaterial device that could be used in super-efficient “thermophotovoltaic” cells to generate electricity from infrared energy, even in the dark (Credit: Stuart Hay, ANU). View gallery (3 images) Using a new optical magnetic metamaterial claimed to have revolutionary properties, physicists from the Australian National University (ANU) and the University […]

Engineer Creates Origami Battery

Mon, 12/21/2015 – 9:34am by Binghamton University Origami, the Japanese art of paper folding, can be used to create beautiful birds, frogs and other small sculptures. Now a Binghamton University engineer says the technique can be applied to building batteries, too. Seokheun “Sean” Choi developed an inexpensive, bacteria-powered battery made from paper, he writes in […]

Storing Electricity In Paper – Paper batteries that charge in seconds

This piece of power paper can store 1F. Researchers at Linköping University’s Laboratory of Organic Electronics, Sweden, have developed power paper — a new material with an outstanding ability to store energy. The material consists of nanocellulose and a conductive polymer. The results have been published in Advanced Science. One sheet, 15 centimetres in diameter […]

Scientists discover how to make batteries from trees

A method for making elastic high-capacity batteries from wood pulp was unveiled by researchers in Sweden and the US. Using nanocellulose broken down from tree fibres, a team from KTH Royal Institute of Technology and Stanford University produced an elastic, foam-like battery material that can withstand shock and stress. “It is possible to make incredible […]

SOON WE WILL BE ABLE TO MAKE JUST ABOUT ANYTHING FROM SAWDUST

This is science at its best: When I was growing up, the only practical use for sawdust was to soak up vomit, but thanks to scientists at a Belgian university who developed a new chemical process, that same sawdust could soon be used in gasoline and other products normally derived from petroleum. Researchers at KU […]

SPRAY-ON SOLAR CELLS WILL REVOLUTIONIZE THE SOLAR INDUSTRY PRICING STRUCTURE

Research scientists at the University of Sheffield have recently developed a technique to make solar panels even more efficient with the creation of spray-on solar cells. With further research and development, this technology may one day replace traditional bulky solar cells with a spray can. The current solar power market is being handicapped by the […]
