Platinum meets its match in quantum dots from coal: New catalyst for fuel cells outperforms platinum Posted: 01 Oct 2014 06:03 AM PDT Scientists combined graphene quantum dots drawn from common coal with graphene oxide, nitrogen and boron into a catalyst for fuel cells that outperforms platinum. Graphene quantum dots grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, making them better than platinum catalysts for certain reactions within fuel cells.

Novel approach to magnetic measurements atom-by-atom Posted: 01 Oct 2014 06:01 AM PDT Having the possibility to measure magnetic properties of materials at atomic precision is one of the important goals of today's experimental physics. Such measurement technique would give engineers and physicists an ultimate handle over magnetic properties of nano-structures for future applications. Researchers now propose a new method, utilizing properties of the quantum world – the phase of the electron beam – to detect magnetism with atom-by-atom precision.
