Researchers grind nanotubes to get nanoribbons: Rice-led experiments demonstrate solid-state carbon nanotube 'templates'

A simple way to turn carbon nanotubes into valuable graphene nanoribbons may be to grind them, according to research led by Rice University.

Argonne scientists announce first room-temperature magnetic skyrmion bubbles: New ideas are bubbling up for more efficient computer memory

Researchers at UCLA and the U.S. Department of Energy's Argonne National Laboratory announced a new method for creating magnetic skyrmion bubbles at room temperature. The bubbles, a physics phenomenon thought to be an option for more energy-efficient and compact electronics, can be created with simple equipment and common materials.

New boron compounds for organic light-emitting diodes: Luminescent blue boron-containing nanographenes are highly promising materials for portable electronic devices

Major advances in the field of organic electronics are currently revolutionising previously silicon-dominated semiconductor technology. Customised organic molecules enable the production of lightweight, mechanically flexible electronic components that are perfectly adapted to individual applications. Chemists at the Goethe University have now developed a new class of organic luminescent materials through the targeted introduction of boron atoms into the molecular structures. The compounds described in the professional journal Angewandte Chemie (Applied Chemistry) feature an intensive blue fluorescence and are therefore of interest for use in organic light-emitting diodes (LED's).
