New Metamaterial Nanocups Brings Superlenses, ultra-efficient solar cells and invisibility closer

Gold nanocups at their magnetoinductive resonance have the unique ability to redirect scattered light in a direction dependent on cup orientation, as a true three-dimensional nanoantenna. Nanocups are just what they sound like: very tiny, cup-shaped particles. What makes them special is their ability to bend light. Halas and Mirin have found a way to …

Carbon Nanotube Yarn Cellphone and Wireless Antennas

University of Cincinnati researchers have taken 25-micron carbon nanotube thread and created a dipole antenna using double-sided transparent tape and silver paste. They were immediately successful in transmitting radio signals. “It transmitted almost as well as the copper did, but at about one ten-thousandth of the weight,” says. They transmitted both AM and FM in …

Battles in Bullet Time: Bionic bullet dodging vs Real Time Guided Sniper Rounds vs Robotic Counter Sniper Fire

There is a patent for a electronically enabled bullet dodging capability. If a sniper is firing from 2500 meters then there is 4 seconds to move out of the way if the bullet can be detected as it emerges from the muzzle. (H/T to Firearm blog The knee reflex takes about 20 milliseconds to fire. …

Nanotech Roundup: Nanolasers, Room Temperature Nanocars, Fast Nanotube Memory, Nanowire Building

This plasmonic whispering gallery microcavity consists of a silica interior that is coated with a thin layer of silver. It improves on the quality of current plasmonic microcavities by better than an order of magnitude and paves the way for plasmonic nanolasers. (Credit: Image courtesy of DOE/Lawrence Berkeley National Laboratory) 1. The principle behind whispering …
