Recycling cathodes Nanoengineers at the University of California San Diego developed an energy-efficient recycling process that restores used cathodes from spent lithium ion batteries. The process involves harvesting the degraded cathode particles from a used battery and then boiling and heat treating them. In new batteries built with the cathodes, charge storage capacity, charging time and ba... » read more

Turning electric signals into light signals Transmitting large amounts of data, such as those needed to keep the internet running, requires high-performance modulators that turn electric signals into light signals, and now, researchers at ETH Zurich have developed a modulator they say is a hundred times smaller than conventional models. They reminded that in 1880, Alexander Graham Bell deve... » read more

Controlling the growth of metal-crystals from single atoms In a breakthrough that allows for observation and direct control of the nano-world in motion, researchers at the University of Warwick have developed a method, called Nanocrystallometry, that allows for the creation of precise components for use in nanotechnology. The method uses a doped-graphene matrix to slow down and then trap at... » read more
