Graphene: Diverse advances

News: Nanotechnology    September 11, 2010
Scientists thought they understood carbon, until nanotechnology came along. Working with carbon at the atomic level (the nanoscale) has revealed many surprising properties. In particular, graphene, a sheet of carbon one atom thick with the atoms arranged in a lattice of hexagons like a honeycomb, has proven to be astonishingly versatile. For example, two recent [...]

A first: Spintronics made visible

News: Quantum Physics    April 27, 2010
It’s an important emerging field, spintronics; though it’s not too well known. It’s based on a quantum property of electrons – they spin. Some electrons spin ‘up,’ some spin ‘down’ and if you can get a device to read that state of up or down, that’s the basis for many kinds of electronics. This includes [...]

Remodeling: A new model for material science

Impact: Quantum Physics    March 24, 2010
At one level this is a simple piece of news, announced by Princeton University (New Jersey, USA): Princeton engineers, led by Emily Carter, Professor of Mechanical and Aerospace Engineering and Applied and Computational Mathematics, have refurbished an 80-year-old mathematical formula to develop a new approach for computer models used in material science. At another level, [...]

Breakthrough will lead to further entanglements

News: Nuclear Physics    January 12, 2010
The title of this post, “Breakthrough will lead to further entanglements” should be taken literally…and figuratively. An experiment by L. G. Herrmann in France, working with colleagues in France, Spain, and Germany, and published in Physical Review Letters has demonstrated for the first time in a solid state device the property of quantum mechanics called [...]
