A new process for growing forests of manganese dioxide nanorods may lead to the next generation of high-performance capacitors. As an energy-storage material for batteries and capacitors, manganese dioxide has a lot going for it: it´s cheap, environmentally friendly and abundant. However, chemical capacitors made with manganese dioxide have lacked the power of the typical carbon-based physical capacitor. Michigan Technological University scientist Dennis Desheng Meng theorized that...


Word of the Day
