A review article summarizes the state-of-the-art knowledge about graphene grain boundaries

The graphene produced by chemical vapor deposition is typically polycrystalline. Authors from the ICN2 Theoretical and Computational Nanoscience Group, led by ICREA Research professor Stephan Roche, together with authors from Sungkyunkwan University, analyse in Advanced Materials the challenges and opportunities of these structures.

'Nano-pixels' promise thin, flexible, high resolution displays

A new discovery will make it possible to create pixels just a few hundred nanometres across that could pave the way for extremely high-resolution and low-energy thin, flexible displays for applications such as 'smart' glasses, synthetic retinas, and foldable screens.

Oxford University technology can draw images 70 micrometers across, each image is smaller than the width of a human hair. The researchers have shown that using this technology they can create 'nano-pixels' just 100 nanometers in size that could pave the way for extremely high-resolution and low-energy thin, flexible displays for applications such as 'smart' glasses, synthetic retinas, and foldable screens.

NASA MESSENGER and STEREO Measurements Open New Window Into High- Energy Processes on the Sun

june-4-2011-flare-stereo_0_0.png
A solar flare erupted on the far side of the sun on June 4, 2011, and sent solar neutrons out into space. Solar neutrons don't make it to all the way to Earth, but NASA's MESSENGER, orbiting Mercury, found strong evidence for the neutrons, offering a new technique to study these giant explosions.
