These bowling pin-looking structures are variable-diameter carbon nanotubes. University of Nebraska-Lincoln electrical engineering professor Dr. Yongfeng Lu discovered laser-based production techniques that can precisely control the length, diameter and properties of carbon nanotubes — no more single-walled boring cylinders here.
Changing a nanotube's diameter from end to end changes its characteristics. Lu envisions variable-diameter nanotubes customized for specific uses.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
