A multi-institutional team of engineers has developed a new approach to the fabrication of nanostructures for the semiconductor and magnetic storage industries. This approach combines top-down advanced ink-jet printing technology with a bottom-up approach that involves self-assembling block copolymers, a type of material that can spontaneously form ultrafine structures.

The team, consisting of nine researchers from the University of Illinois at Urbana-Champaign, the University of Chicago and Hanyang University in Korea, was able to increase the resolution of their intricate structure fabrication from approximately 200 nanometers to approximately 15 nanometers. A nanometer is a billionth of a meter, the width of a double-stranded DNA molecule. (more…)

Insect eye-inspired camera captures wide field of view with no distortion, according to study co-led by CU-Boulder

By mimicking the bulging, bowl-shaped eyes possessed by dragonflies, praying mantises, houseflies and other insects, a team of researchers that includes a University of Colorado Boulder engineer has built an experimental digital camera that can take exceptionally wide-angle photos without distorting the image.

To create the innovative camera, which also allows for a practically infinite depth of field, the scientists used stretchable electronics and a pliable sheet of microlenses made from a material similar to that used for contact lenses. The researchers described the camera in an article published on May 1, 2013 in the journal Nature. (more…)

Earthquakes, Glue and Grappling Hooks: Scientists Dissect the Movement of Bacteria

A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has discovered that microscopic bacteria have a lot in common with earthquakes — when it comes to their jolting movements.

In a new study published in the peer-reviewed Proceedings of the National Academy of Sciences, the scientists also report that a molecular “glue” produced by the bacteria to help them adhere to surfaces also acts as a sort of transportation lubricant, helping them move and organize into rudimentary social structures. These discoveries, they say, could lead to new ways to combat harmful microbes in the long term. (more…)

Emily Chen still vividly remembers the lecture on gecko feet. She was an eighth grader attending Berkeley Lab’s Nano*High program to hear materials scientist Arun Majumdar explain how what he was learning about gecko feet might translate into a new adhesive product based on carbon nanotubes.
