Novel supercapacitor architecture provides 2x more power performance May 19, 2014 Novel supercapacitor architecture provides 2x more power performance A novel nanometer scale ruthenium oxide anchored nanocarbon graphene foam architecture that is claimed to provide two times more energy and power compared to supercapacitors has been developed by researchers at the University of California, Riverside. Read more Silicon dioxide nanotubes help batteries last 3x longer May 19, 2014 Silicon dioxide nanotubes help batteries last 3x longer Researchers at the University of California, Riverside Bourns College of Engineering have used a material found in surgical tubing to develop a way to make lithium-ion batteries that last three times longer between charges compared to the current industry standard. Read more Terahertz power meter: High accuracy through calorimeter principle May 18, 2014 Terahertz power meter: High accuracy through calorimeter principle In most application fields, an accuracy of ±8% might not be overwhelming, but when it comes to terahertz (THz) field strength, ±8% is impressive. Chip test equipment manufacturer Advantest now offers a terahertz power meter that features such an accuracy. Potential customers are expected ... Read more Piezoelectric nanogenerator efficiency gain drives commercialization advance May 16, 2014 Piezoelectric nanogenerator efficiency gain drives commercialization advance Scientists at The Korea Advanced Institute of Science and Technology (KAIST) have paved the way for the commercialization of nanogenerators by developing a technique to transfer a piezoelectric thin film from sapphire substrates to plastic substrates using laser lift-off (LLO). Read more Airborne wind turbine doubles energy output tower-mounted turbines May 15, 2014 Airborne wind turbine doubles energy output tower-mounted turbines Altaeros Energies, a startup launched out of MIT, has developed the world’s first commercial airborne wind turbine, which uses a helium-filled shell to float as high as a skyscraper to produce double the energy of similarly sized tower-mounted turbines. Read more Flexible CIGS solar cells claim efficiency record May 14, 2014 Flexible CIGS solar cells claim efficiency record Midsummer, a Swedish production line supplier for flexible thin film CIGS solar cells has increased the efficiency of the company's solar cells from 15 per cent to 16.2 per cent for a 156 × 156 mm solar cell aperture area. Read more Scientists seek direct approach to overhaul power grid May 14, 2014 Scientists seek direct approach to overhaul power grid Scientists at The Fraunhofer Institute for Integrated Systems and Device Technology IISB in Erlangen, Germany are calling for a radical overhaul of power grid technology and how it is managed using high-efficiency power electronics to address future demands. Read more Dual carbon battery charges 20x faster than lithium-ion batteries May 13, 2014 Dual carbon battery charges 20x faster than lithium-ion batteries Japanese start-up Power Japan Plus has launched a new battery technology that claims to offer a more sustainable, safer, longer-lasting and cost-effective battery technology with an energy density comparable to a lithium ion battery. Read more Fiber supercapacitor aims to power wearable devices May 13, 2014 Fiber supercapacitor aims to power wearable devices Scientists at Nanyang Technological University (NTU) in Singapore, Tsinghua University in China, and Case Western Reserve University in the USA claim to have developed a fiber supercapacitor that can be woven into clothing and power wearable medical monitors and communications. Read more Hyperbolic metamaterials pave way for high-performance solar cells May 13, 2014 Hyperbolic metamaterials pave way for high-performance solar cells Researchers at Purdue University claim to have taken a step toward practical applications for 'hyperbolic metamaterials', which are ultra-thin crystalline films that could bring optical advances including high-performance solar cells, powerful microscopes and quantum computers.
