Cu nano particles supported on graphene oxide nano sheets (CuNPs@GO) for novel synthesis of N-(phenyl(4-phenyl-1H- 1,2,3- triazol yl) methyl) benzamine
Graphene oxide supported metallic nanoparticles such as Cu, Ag, Pd, ... has been used as heterogeneous catalyst for the synthesis of 1, 2, 3- triazoles[1,2]. In this work we hope to use CuNPs@GO as an efficient catalyst in the synthesis of N...
AgNPs GO nano sheets for Aerobic Aqueous Oxidations of Alcohols
Graphene-based nanosheets have attracted remarkable attention in recent years
since their discovery in 2004. One of the major concerns in the area of graphene-based
materials relates to the stabilization of the exfoliated sheets...
Zirconium (IV) porphyrin graphene oxide: a new and efficient catalyst for the synthesis of 3,4‐dihydropyrimidin‐2(1H)‐ones
A covalently cross‐linked graphene oxide (GO) as a catalyst was prepared by a cross‐linking process using the nucleophilic reaction of zirconium (IV)‐coordinated 5,10,15,20‐tetrakis (aminophenyl)porphyrin (ZrPPh) with carboxyl groups of the edges of...
A reconfigurable multi-band, multi-bias THz absorber
A configurable terahertz (THz) graphene-based metamaterial absorber is designed in this paper.
Taking advantage of dual bias graphene ribbons and disks with a golden plate, the reconfigurable
absorber achieves absorption over 90% in three...
Synthesis and characterization of graphene oxide via Chemical Vapor Deposition method on copper substrate
Recently, graphene oxide has attracted researchers’ attention because of its outstanding and unique chemical, optical, electrical and mechanical properties. In this research, graphene oxide nano-sheets were grown on catalytic copper substrate...
Investigating the nature of graphene based films prepared by vacuum filtration of graphene dispersions
Energy transfer in strained graphene assisted by discrete breathers excited by external ac driving
In the present molecular-dynamics study, external ac driving is used at frequencies outside the phonon spectrum to excite gap DBs in uniformly strained graphene nanoribbon. Harmonic displacement or harmonic force is applied to a zigzag atomic chain...
