Engineering graphene by oxidation: a first principles study [PDF]
Nanotechnology 21 (4), 045704-7 (2010), 2009 Graphene epoxide, with oxygen atoms lining up on pristine graphene sheets, is investigated theoretically in this Letter. Two distinct phases: metastable clamped and unzipped structures are unveiled in consistence with experiments. In the stable (unzipped) phase, epoxy group breaks underneath sp2 bond and modifies the mechanical and electronic ...

First-principles investigation of Ag-Cu alloy surfaces in an oxidizing environment [PDF]
, 2007 In this paper we investigate by means of first-principles density functional theory calculations the (111) surface of the Ag-Cu alloy under varying conditions of pressure of the surrounding oxygen atmosphere and temperature. This alloy has been recently proposed as a catalyst with improved selectivity for ethylene epoxidation with respect to pure ...

Ag-Cu alloy surfaces in an oxidizing environment: a first-principles study [PDF]
, 2008 Recent experiments on model catalysts have shown that Ag-Cu alloys have improved selectivity with respect to pure silver for ethylene epoxidation. In this paper we review our first-principles investigations on the (111) surface of this alloy and present new findings on other low index surfaces.
