Reconstructing the evolution of dark energy with variations of fundamental parameters

N. J. Nunes, T. Dent, C. J. A. P. Martins +1

Under the assumption that the variations of parameters of nature and the current acceleration of the universe are related and governed by the evolution of a single scalar field, we…

Subjecting a graphene monolayer to tension and compression

Georgia Tsoukleri, John Parthenios, Konstantinos Papagelis +5

The mechanical behaviour of graphene flakes under both tension and compression is examined using a cantilever-beam arrangement. Two different sets of samples were employed involvin…

Patterns in Flowing Sand: Understanding the Physics of Granular Flow

Tamas Borzsonyi, Robert E. Ecke, Jim N. McElwaine

Dense granular flows are often unstable and form inhomogeneous structures. Although significant advances have been recently made in understanding simple flows, instabilities of suc…
