Now, researchers at Toyohashi Tech and Duke University have found a way to produce new copper alloy nanoparticles, which can be used as the main component of affordable conductive inks with high oxidation resistance. The researchers electrically exploded alloy or twisted metal wires in water with a mild reducing agent (Vitamin C) in order to produce the nanoparticles.

Iranian researchers from Tehran University of Medical Sciences in association with American researchers succeeded in the production of nanostructures whose main application is in the treatment of damaged heart tissues after a heart attack.

This self-portrait of NASA's Mars rover Curiosity combines dozens of exposures taken by the rover's Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of Curiosity's work on Mars (Feb. 3, 2013), plus three exposures taken during Sol 270 (May 10, 2013) to update the appearance of part of the ground beside the rover.

These images of an asteroid 3,600 feet (1,100 meters) long were taken on Dec. 17 (left) and Dec. 22 by scientists using NASA's giant Deep Space Network antenna at Goldstone, California. This asteroid will safely fly past Earth on Dec. 24, at a distance of 6.8 million miles (11 million kilometers).

The research was carried out at laboratorial scale, and nanostructures were synthesized through a simple and economic method with the ability to be mass produced.
