Atom-by-atom assembly makes for cheap, tuneable graphene nanoribbons
Posted by Quinn Sena in categories: computing, particle physics
The wonder material graphene can take many forms for many different purposes, from transparent films that repel mosquitoes to crumpled balls that could boost the safety of batteries. One that has scientists particularly excited is nanoribbons for applications in energy storage and computing, but producing these ultra-thin strips of graphene has proven a difficult undertaking. Scientists are claiming a breakthrough in this area, devising a method that has enabled them to efficiently produce graphene nanoribbons directly on the surface of semiconductors for the first time.
As opposed to the sheets of carbon atoms arranged in honeycomb patterns that make up traditional graphene, graphene nanoribbons consist of thin strips just a handful of atoms wide. This material has great potential as a cheaper and smaller alternative to silicon transistors that would also run faster and use less power, or as electrodes for batteries that can charge in as little as five minutes.
“This is why many research groups around the world are focusing their efforts on graphene nanoribbons,” explains study author and chemist, Professor Konstantin Amsharov from Germany’s Martin Luther University of Halle-Wittenberg (MLU).

The power struggle that resides within our brain
Posted by Genevieve Klien in category: neuroscience
Our brain is divided. We just don’t know it. Or we do, but not in the way one thinks. To put it simply – a power struggle has been going on between the left side of our brain, or the analytical side, and the right side, the emotional side. It’s been going on for quite some time.
There have always been rumblings of the imbalance between the two for years, certainly covered off in a critical work of near genius by renowned psychiatrist and neuroscientist Dr. Iain McGilchrist, (iainmcgilchrist.com), author of the acclaimed The Master and his Emissary: the Divided Brain and the Making of the Western World.

Team develops method for trapping elusive electrons
Posted by Genevieve Klien in categories: computing, nanotechnology, quantum physics
Graphene’s unique 2-D structure means that electrons travel through it differently than in most other materials. One consequence of this unique transport is that applying a voltage doesn’t stop the electrons like it does in most other materials. This is a problem, because to make useful applications out of graphene and its unique electrons, such as quantum computers, it is necessary to be able to stop and control graphene electrons.
An interdisciplinary team of scientists from the Universidad Autonoma de Madrid (Spain), Université Grenoble Alpes (France), International Iberian Nanotechnology Laboratory (Portugal) and Aalto University has solved this long-standing problem. The team included experimental researchers Eva Cortés del Río, Pierre Mallet, Héctor González‐Herrero, José María Gómez‐Rodríguez, Jean‐Yves Veuillen and Iván Brihuega and theorists including Joaquín Fernández-Rossier and Jose Lado, assistant professor in the department of Applied Physics at Aalto.
The experimental team used atomic bricks to build walls capable of stopping the graphene electrons. This was achieved by creating atomic walls that confined the electrons, leading to structures whose spectrum was then compared with theoretical predictions, demonstrating that electrons were confined. In particular, it was obtained that the engineered structures gave rise to nearly perfect confinement of electrons, as demonstrated from the emergence of sharp quantum well resonances with a remarkably long lifetime.
