In this work carbon based nanomaterials in ionic liquids have been studied as potential electrolytes for dye sensitised solar cells (DSSCs). Graphene, single wall carbon nanotubes (SWCNTs) and a mixture of graphene and SWCNTs were incorporated into 1-methyl-3-propylimidazolium iodide (PMII) ionic liquid. The resulting quasi-solid state electrolytes were sandwiched between TiO2 working electrode...

In this paper, the in-plane torsional properties of two dimensional nanomaterials are revealed to be tunable by surface functionalization using molecular dynamics simulations. The torsional strengths of both graphene and graphyne under circular shearing are found to first decrease and then increase anomalously with the increase of the hydrogenation ratio. The minimum strength of such U-shaped s...

Electrogenerated chemiluminescence (ECL) can be obtained from an electrochemically oxidized highly oriented pyrolytic graphite electrode or a graphene oxide suspension in an aqueous solution containing 0.1 M NaClO(4), phosphate buffer (PBS) (pH = 7.0) and 13 mM tri-n-propylamine. Single ECL events from individual graphene oxide nanosheets can be observed. The observation of ECL in such systems ...

Carbon nanotubes (CNTs) and graphene nanoribbons (GNRs) represent a novel class of lowdimensional materials.
