Computer simulations predict a liquid phase in atomically thin golden islands that patch small pores of graphene. According to the simulations, gold atoms flow and change places in the plane, while the surrounding graphene template retains the planarity o

Quantum-mechanical Models Predict New Phase of Matter

May 22, 2015 10:27 am | by Academy of Finland | News | Comments

Computer simulations have predicted a new phase of matter, an atomically thin two-dimensional liquid. This prediction pushes the boundaries of possible phases of materials further than ever before. Two-dimensional materials themselves were considered impossible until the discovery of graphene around 10 years ago. However, they have been observed only in the solid phase, because the thermal atomic motion required for molten materials...

How is lightning initiated in thunderclouds? This is difficult to answer — how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, that cosmic rays provide suitable probes to measure electric fields within thunderclouds. The measurements, including the strength of the electric field at a certain height in the cloud, were performed with the LOFAR radio telescope.
