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…)

Warning system to protect astronauts from solar storms

Massive explosions on the sun unleash radiation that could kill astronauts in space.

Now, researchers from the U.S. and South Korea have developed a warning system capable of forecasting the radiation from these violent solar storms nearly three hours (166 minutes) in advance, giving astronauts, as well as air crews flying over Earth’s polar regions, time to take protective action.

Physicists from the University of Delaware and from Chungnam National University and Hanyang University developed the system and report on it in Space Weather: The International Journal of Research and Applications, published by the American Geophysical Union. The research article also is selected as an “Editor’s Highlight.” (more…)
