Interlayer interaction and disorder in Few Layer Graphene (FLG) powders prepared by fluidized bed chemical vapor deposition

Bacsa R., Bacsa W.S., Serp Ph., Lecante P., Pavlenko E., Cameán I., Ramos A., Garcia A.B., Bacsa R., Bacsa W.S., University of Toulouse, FR

The growth of few layer graphene (FLG) in powder form by CVD is particularly promising for its large scale production and use in composites as well as electrochemical and energy applications. The electronic and mechanical [...]

Polymer nanocomposites reinforced with nanoparticles extracted from renewable resources

Dufresne A., Grenoble institute of technology, FR

There has been an explosion of interest in the use of biomass as a source of renewable energy and materials. One focus of this activity has followed from the recognition that, by suitable chemical and [...]

Charge Amplification of a Graphene-integrated-CMOS (GIC) RF Detector

Ordonez R.C., Hayashi C., Kamin N., de Andrade M.C., Garmire D., University of Hawaii at Manoa, US

A novel approach is demonstrated to characterize the charge amplification of mono-layered graphene as an integral part of a Complementary Metal Oxide Semiconductor Device (CMOS) under RF radiation. We have verified that charge carriers generated [...]

The preparation and characterization of the Graphene-Like YBO3:Ce3+

Wang Y., Wang Z.Z., Hu X.Y., Wang Y., Wang Z.Z., Zhan S.C., Sun Q., Sun X., Miao H., Sun Q., Sun X., Hao Y.Y., Northwest University, CN

In this study, a new material of Graphene-Like YBO3:Ce3+ phosphors was synthesized by solvothermal method and layered by liquid exfoliation treatment, and it is the material with layered structure. SEM image shows that the thickness [...]

Soluble Graphene Hybrid Composite (GHC) by Physical Functionalization

Le G.V., Le T.M., Dinh D., Dinh H., Dinh D., Dinh H., Nguyen K.C., Nguyen T.T., Nguyen K.C., Nguyen T.T., Le G.V., Le T.M., DHK GRAPHENOLOGIES LLC, US

Generally speaking, the CVD process of CH4 gas on copper substrate renders a rigid and conductive film from extended graphene molecule which is hard to be produced in large scale. The graphene oxide (GO) is [...]

Synthesis of nano carbons using plasma reactor

Paukner C., Juda K., Pennington D., Clayton A., Koziol K., Cambridge Nanosystems Ltd., UK

We are presenting a method of continuous synthesis of nano carbons from a gaseous hydrocarbon feedstock in our plasma reactor system. Controlling the operation parameters of the non-equilibrium inert/hydrocarbon gas plasma from our in-house designed [...]

Dynamics of carbon nanopillar growth on bulk and thin substrates irradiated by a focused electron beam

Zhdanov G.S., Manukhova A.D., Lozhkin M.S., St. Petersburg State University, RU

Here we compare successive stages of carbon nanopillar growth on various substrates irradiated by a 20keV electron beam focused to a spot of 1 nm diameter. The hydrocarbon molecules present in the residual atmosphere of [...]

Dispersion of Carbon Nanotubes with Organic Dyes

Zhang W., Wu C., Zhang W., Dalian University of Technology, CN

Owing to the presence of van der Waals’ forces, carbon nanotubes (CNTs) have the propensity to aggregate together and form bundles, which considerably hinders their applications. In this paper, organic dyes were used to suspend [...]

3-D characterization of carbon nanotube-polymer composites using scanning electron microscopy and confocal Raman microscopy

Zhao M.H., Cannara R.J., National Institute of Standards and Technology, US

3D characterization of the dispersion of CNTs in a polymer matrix is a critical step toward understanding and improving the performance of CNT polymer composites. In this study, SEM and confocal Raman microscopy (CRM) were [...]

Inducing Aromaticity Patterns and Tuning the Electronic Transport of Graphene Nanoribbons via Edge Design

Fias S., Martin-Martinez F.J., Van Lier G., De Proft F., Geerlings P., Free University Brussels (VUB), BE

Tuning the band gap of graphene nanoribbons (GNR) by chemical edge functionalisation is a promising approach towards future electronic devices based on graphene. The band gap is closely related to the aromaticity distribution and therefore [...]
