A novel nano-porous 3D architecture of N-doped carbon nanorods arrays grown on the surface of graphene has been prepared by carbonizing polyaniline/graphene oxide (PANI-GO) composite with PANI nanorod arrays on both sides of GO nanosheets. The obtained carbon materials are entirely composed of regularly grown carbon nanorods on graphene with height of about 100 nm and width about 30 nm, showing...

   Here, we report that the reduced graphene oxide nanosheets were successfully synthesized using the ‎Lactobacillus plantarum biomass in a simple, environmentally friendly and scalable manner. We ‎produced graphene oxide by oxidization and exfoliation of graphite flakes with modified Hummer's ‎method and then reduced to reduced graphene oxide by using Lactobacillus plantarum biomass as a ‎...

the combination of graphene (gr) and nickel oxide nanoparticles (nio nps) yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. in cyclic voltammetry (cv) studies, in the presence of ep, nio/gr composite modified electrode shows a significantly higher current response for ep oxidation. based on differential pulse voltamm...

We propose a hybrid nano-structuring scheme for tailoring thermal and thermoelectric transport properties of graphene nanoribbons. Geometrical structuring and isotope cluster engineering are the elements that constitute the proposed scheme. Using first-principles based force constants and Hamiltonians, we show that the thermal conductance of graphene nanoribbons can be reduced by 98.8% at room ...

C 2012 American Chemical Society Graphene: The Game Changer? I t has only been eight years since the isolation of graphene 1 and over a year since the 2010 Nobel Prize in Physics was jointly awarded to Andre Geim and Konstantin Novoselov “for groundbreaking experiments regarding the two-dimensional material graphene.” Nevertheless, the number of graphene publications is still rapidly growing. T...

By merging bottom-up and top-down strategies we tailor graphene's electronic properties within nanometer accuracy, which opens up the possibility to design optical and plasmonic circuitries at will. In a first step, graphene electronic properties are macroscopically modified exploiting the periodic potential generated by the self assembly of metal cluster superlattices on a graphene/Ir(111) sur...

Nano-impact chronoamperometric experiments are a powerful technique for simultaneously probing both the potential of zero charge (PZC) and the diffusion coefficient (D0) of graphene nanoplatelets (GNPs). The method provides an efficient general approach to material characterisation. Using nano-impact experiments, capacitative impacts can be seen for graphene nanoplatelets of 15 μm width and 6-8...

The phase of graphene plasmon upon edge-reflection plays a crucial role on determining the spectral properties of graphene structures. In this article, by using the full-wave simulation, we demonstrate that the mid-infrared graphene plasmons are nearly totally reflected at the boundary together with a phase jump of approximately 0.27π, regardless of the environments surrounding it. Appling this...

Nano fluids are having wide area of applications in heat transfer equipments. In the present work graphene nanoparticles, Dispersed in De-ionized water (DI), Ethylene Glycol (EG) based nano fluids were developed. Thermal conductivity and convective heat transfer properties of these nanofluids were systematically investigated. In the present investigation thermal convection of glycol based nanof...
