Engineers at Stanford University have found a way to add these delicate, bulbous decorations to nanowires that are about 1/1000th the width of a human hair. The decorations are could be important to creating more efficient batteries, solar cells and other nanotechnology-enabled inventions in the future. Several research groups have come up with different ways to add tiny hairs, branches, bumps and folds to nanowires. But the new Stanford method is simple, works for wires made of many different materials and loads up the wires with an extra dose of decorations, according to a paper the researchers published April 11 in the journal Nano Letters.
