An ASU engineering student has shown his school spirit in a small way--by creating a microscopic etching of Sparky, the Sun Devil mascot, that's smaller than a human red blood cell. --by Chelsea Brown

Nanotechnology is a world of the minuscule. By manipulating matter at atomic and molecular levels, scientists have the potential to radically change consumer technology, health care, energy, and national security.

NJ Tao and colleagues have developed two different chemical sensors based on the tiny quartz tuning forks used in wristwatches. --by Linley Erin Hall

As consumer electronics such as MP3 players and digital cameras shrink, the need to put more memory in a smaller space grows. Traditional electronics begin to break down at the nanoscale, or molecular level. Researchers at ASU are working to overcome these limitations using nanoionics, a technique for moving ions around on a chip. --by Nicholas Gerbis

Imagine that an antenna has a kind of eyesight. Engineers and scientists are trying to better focus that eyesight in certain directions. They want to extend its reach over various distances without disturbance or interference from things they don't want the antenna to "see."--by Joe Kullman

Humans have a set of built-in chemical-detection devices. For example, the nose identifies chemicals by their smells. The tongue identifies chemicals by their tastes. Computers, on the other hand, do not have this skill. Researchers at ASU are hoping to allow computers to interact with the chemical world using nano-sized sensors that recognize molecules. --by Linley Erin Hall

The Electromagnetic Anechoic Chamber. It doesn't sound like a place you would choose to enter voluntarily. But for Constantine Balanis, it's the ultimate playroom. Experiments in the dark chamber shed light on the workings of electromagnetic waves. --by Joe Kullman

Smart cars and smart phones already exist. Engineers at ASU say that making antenna systems ‘smarter' promises to further expand the horizons of the wireless communications world. --by Joe Kullman
