The morphologies/dimensions of Au nanostructures can be tailored by merely controlling the reduction degree of graphene oxide surface. Au nanoparticles, long Au nanowires, and semicircular-shaped Au nanoplates are in situ synthesized on slightly, moderately, and highly reduced graphene oxide films respectively, without the need of any templating agent.

Three-dimensional graphene-based structures such as graphene aerogels or foams have shown applications in energy, environmental matters, and many other areas. Here, we present a method to convert raw cotton into functional aerogels containing a significant amount of nitrogen-doped graphene (N-graphene) sheets grafted on carbonized cellulose fibers. Urea was introduced into raw cotton as a molec...

Wrinkles in graphene with desirable morphology have practical significance for electronic applications. Here we carry out a systematic molecular dynamics study of the wrinkling instability of graphene on substrate-supported nanoparticles (NPs). At a large NP dispersion distance, a monolayer graphene adheres to the substrate and bulges out locally to wrap around individual NPs, forming isolated ...

To clarify the yielding mechanism of small hydrocarbon molecules in chemical sputtering between hydrogen and graphene sheets, we made classical molecular dynamics simulation with modified Brenner’s REBO potential which we proposed to deal with chemical reaction. As the simulation model, we prepared more realistic physical system, which is composed of 160 incident hydrogen atoms and ten graphene...

A fibre-shaped solid electrochemical capacitor based on electrochemically reduced graphene oxide has been fabricated, exhibiting high specific capacitance and rate capability, long cycling life and attractive flexibility.

micromixers are one of the most crucial components of lab-on-a-chip devices with the intention of mixing and dispersion of reagents like small molecules and particles. the challenge facing micromixers is typically insufficient mixing efficiency in basic designs, which results in longer microchannels. therefore, it is desirable to increase mixing efficiency, in order to decrease mixing length, w...

In this work, a plasmonic right-angled waveguide bend and divider are proposed. Using the Transformation Optics (TO) approach transformation media of T-shaped obtained. Such with continuous refractive index realized help graphene in terahertz frequency range, key to effectively guiding surface plasmon polariton (SPP) propagation on 90 degree curves. Components such capability promising for THz ...
