| New design for mobile phone masts could cut carbon emissions Posted: 22 Apr 2014 08:33 AM PDT A breakthrough in the design of signal amplifiers for mobile phone masts could deliver a massive 200MW cut in the load on UK power stations, reducing carbon dioxide emissions by around 0.5 million tonnes a year. Researchers have designed an amplifier that works at 50 percent efficiency compared with the 30 percent now typically achieved. |
| High-performance, low-cost ultracapacitors built with graphene and carbon nanotubes Posted: 22 Apr 2014 08:32 AM PDT By combining the powers of two single-atom-thick carbon structures, researchers have created a new ultracapacitor that is both high performance and low cost. The device capitalizes on the synergy brought by mixing graphene flakes with single-walled carbon nanotubes, two carbon nanostructures with complementary properties. |
