Reduced graphene oxide-osmium (rGO-Os) hybrid nano dendtrites have been prepared by simple liquid/liquid interface method for the first time. The method involves the introduction of phase-transfered metal organic precursor in toluene phase and GO dispersion in the aqueous phase along with hydrazine hydrate as the reducing agent. Dendritic networks of Os nanoparticles and their aggregates decora...

Large-scale vertically aligned ZnO nanowires with high crystal qualities were fabricated on thin graphene oxide films via a low temperature hydrothermal method. Room temperature photoluminescence results show that the ultraviolet emission of nanowires grown on graphene oxide films was greatly enhanced and the defect-related visible emission was suppressed, which can be attributed to the improve...

Graphene oxide nanoribbons for efficient and stable polymer solar cells are discussed. With controllable bandgap, good solubility and film forming property, graphene oxide nanoribbons serve as a new class of excellent hole extraction materials for efficient and stable polymer solar cells outperforming their counterparts based on conventional hole extraction materials, including PEDOT:PSS.

Remote epitaxy is a recently discovered type of epitaxy, wherein single-crystalline thin films can be grown on graphene-coated substrates following the crystallinity substrate via remote interaction through graphene. Although provides pathway to form freestanding membranes by controlled exfoliation film at graphene interface, implementing not straightforward because atomically precise control i...

Abstract Graphene lithography is crucial for various graphene‐based devices, showing considerable potential in the fields of energy, environment, electronics, and optics. Recent reports show that graphene can be facilely fabricated simultaneously patterned without masks via laser direct writing on a oxide (GO) film. Thus, this laser‐reduced (LRGO) successfully applied holograms with advantages ...

The excellent electrical, optical and mechanical properties of graphene have driven the search to find methods for its large-scale production, but established procedures (such as mechanical exfoliation or chemical vapour deposition) are not ideal for the manufacture of processable graphene sheets. An alternative method is the reduction of graphene oxide, a material that shares the same atomical...
