Simpler nanowires

A "simple" one-step method for growing germanium nanowires from aqueous solution for use in making the next generation of lithium-ion rechargeable batteries has been developed by researchers at Missouri University of Science and Technology. Jay Switzer and colleagues discovered that their well-known electrodeposition technique for nano construction was not thermodynamically feasible for growing nanowires from aqueous solutions so they turned to liquid metal electrodes for the present work; a technique devised by Stephen Maldonado's team at the University of Michigan. Electrochemical liquid-liquid-solid process allowed them to reduce indium tin oxide (ITO) to indium nanoparticles in a solution containing germanium(IV) dioxide and then to crystallize the nanowires from this mixture.
