(PhysOrg.com) -- Although lasers come in all shapes and sizes, one of the most recent laser designs is especially intriguing, since it’s made of just a single nanowire. Due to its small size and simplicity, the single-nanowire ...
(PhysOrg.com) -- Scientists have no problem making a menagerie of nanometer-sized objects -- wires, tubes, belts, and even tree-like structures. What they sometimes have been unable to do is explain precisely how those objects ...
