Power/Performance Bits: Jan. 24


Printable circuits with silver nanowires Scientists at Duke University compared the conductivity of films made from different shapes of silver nanostructures and found that electrons move through films made of silver nanowires much easier than films made from other shapes, like nanospheres or microflakes. In fact, electrons flowed so easily through the nanowire films that they could function... » read more
