Stanford Engineers Working to Pack More Laser Beams, and Data, into Fiber Optic Strands
“In theory one fiber could transport perhaps as many as a hundred different beams, each carrying its own data stream of light flashing on and off,” said David Miller, the W. M. Keck Professor of Electrical Engineering at Stanford. “Our challenge is creating the optics to gather those beams, flow them through the fiber together and then separate out each data stream at the other end.”

Water makes wires even more nano
Water is the key component in a Rice University process to reliably create patterns of metallic and semiconducting wires less than 10 nanometers wide. The technique by the Rice lab of chemist James Tour builds upon its discovery that the meniscus – the curvy surface of water at its edge – can be an effective mask to make nanowires. The Rice team of Tour and graduate students Vera Abramova and Alexander Slesarev have now made nanowires between 6 and 16 nanometers wide from silicon, silicon dioxide, gold, chromium, tungsten, titanium, titanium dioxide and aluminum. They have also made crossbar structures of conducting nanowires from one or more of the materials.

Landmark study proves that magnets can control heat and sound
Researchers at The Ohio State University have discovered how to control heat with a magnetic field. An experiment proved that the phonon—the elementary particle that carries heat and sound—has magnetic properties. Here Joseph Heremans, Ohio Eminent Scholar in Nanotechnology, holds an artist’s rendering of a phonon heating solid material.

UW scientists build a nanolaser using a single atomic sheet
University of Washington scientists have built a new nanometer-sized laser — using the thinnest semiconductor available today — that is energy efficient, easy to build and compatible with existing electronics.

Squid-inspired ‘invisibility stickers’ could help soldiers evade detection in the dark
Squid are the ultimate camouflage artists, blending almost flawlessly with their backgrounds so that unsuspecting prey can’t detect them. Using a protein that’s key to this process, scientists have designed “invisibility stickers” that could one day help soldiers disguise themselves, even when sought by enemies with tough-to-fool infrared cameras.
