'Nano machine shop' shapes #nanowires, #graphene.

The team at Purdue University used a technique called laser shock induced shaping to stamp nano and microgears, form tiny circular shapes from graphene and change the shape of silver nanowires. "We do this shaping at room temperature and atmospheric pressure, like a nano machine shop," said Gary Cheng, an associate professor of industrial engineering at Purdue. The researchers say that their method can tune nanowires by altering electrical and optoelectrical properties that are critical for electronic components, as well as change the properties of graphene, which is a step towards harnessing the material for electronic applications. The technique works by using a multilayered sandwich structure with a tiny mold at the bottom. Nanowires are situated directly above the mold, and other materials are layered between the nanowires and a glass cover sheet. Exposing this layered...
