Unraveling atomic-scale edge structure of nanoscale graphene islands

This is the first demonstration, combining experiment and theory, that the interaction of the carbon atoms with a metal substrate stabilizes the low coordinated carbon edge atoms. In models for the growth of graphene on metal substrates, such low coordinated atoms at the growing edge play a special role. These results, which demonstrate such stability, will play a significant role in further development of these models and will help guide future strategies to grow graphene nanostructures with atomic scale control of edge structure.

Silicon sponge improves lithium-ion battery performance

The lithium-ion batteries that power our laptops and electric vehicles could store more energy and run longer on a single charge with the help of a sponge-like silicon material. Researchers developed the porous material to replace the graphite traditionally used in one of the battery's electrodes, as silicon has more than 10 times the energy storage capacity of graphite.

The quantum dance of oxygen

Under extremely high pressure conditions oxygen molecules group into quartets and give rise to a 'dance of their magnetic moments'. This results in magnetic properties never previously observed in these conditions and in theory points to the existence of a new phase of the element, called epsilon 1.
