Hexa-peri-hexabenzocoronene-porphyrinoids as models for functional graphenes in the development of newer materials

Chauhan S.M.S., University of Delhi, IN

Polycyclic aromatic hydrocarbons are important building blocks for the construction of organic semiconducting materials. Functional hexa–peri-hexabenzocoronenes are important polycyclic hydrocarbons with D6h symmetrical structure containing 13 fused benzene rings and there are more than five [...]

Electrochemical and textural characterization of RuO2-SnO2-graphene under co-precipitation / hydrothermal conditions

Leng X., Zou J.P., Xiong X., He H.W., Central South University, CN

In this report, ternary composite of RuO2-SnO2-graphene with different input ratio of RuCl3, SnCl2 and graphene oxides were prepared by using co-precipitation / hydrothermal approaches followed by thermal treatment. SEM, TEM, and XRD were used [...]

Synthesis, Characterization and magnetic properties of Graphene /Nickel nanocomposites: The role of reducing agent on nanoparticle size and morphology

Salimian M., Titus E., Goncalves G., Bdkin I., Ferro M., Ventura J., Dias C.C., Nanoengineering Research Group (NRD), PT

Graphene oxide (GO) synthesized by modified Hummers used as substrate for the controlled growth of nickel nanoparticles via hydrothermal treatment. Hydrazine hydrate were used as a complex agent for the effective control of the size, [...]

Effect of the Kind of Carbon-Based Nanofiller on the Electrical Conductivity and Rheological Melt Behavior of Polypropylene Composites

Garzón C., Palza H., Quijada R., Universidad de Chile, CL

Recent interest in the use of nanoparticles for the manufacture of polymer composites has arisen due to the striking improvements in some properties achieved at lower loadings compared to micrometer fillers. In particular, derivatives of [...]

Preparation of electrical conductive polymer/graphite oxide composites through the functionalization of graphite oxide sheets

Beyou E., Guimont A., Cassagnau P., Martin G., Sonntag P., Lyon1 University, FR

The preparation of polyethylene/graphite oxide composites exhibiting rheological and electrical percolation thresholds was accomplished by radical addition reactions onto the unsaturated system of graphite oxide sheets through the use of pentadecane and polyethylene in presence [...]

Synthesis of Reduced Graphene Oxide Films using Atmospheric Plasma and Furnace Annealing

Ayler R., Tong Y., Ramabadran U., Zhou X., Ryan G., Farhat S., Kettering University, US

Graphene oxide (GO) is an electrical insulator with good mechanical and thermal properties. It exhibits increased conductivity when the Carbon to Oxygen ratio is high. Our work aims to efficiently fabricate inexpensive flexible reduced graphene [...]

A reliable supply platform for Graphene and other 2D Materials

Goodwin A., Ladislaus P., McHale R., Van Fleet C., Thomas Swan & Co.Ltd., UK

Thomas Swan Advanced Materials division is devoted to the development of high value materials for emerging technologies. In 2014, we launched a new range of high quality, few layer graphene nanoplatelet products - these materials [...]

Maskless Lithography of Nanometer-Scale Circuit Structures in Supported, Single-Layer Graphene Using Helium Ion Microscopy

Rondinone A., Iberi V., Matola B., Linn A., Joy D., Oak Ridge National Laboratory, US

Here we will discuss the utility of scanning helium ion lithography for fabricating conducting graphene structures that are supported directly by silicon oxide. The lithography is performed in a single step, dry, using high-resolution He- [...]

Application of chemiluminescent resonance energy transfer and graphene sheet for the rapid quantification of mercury in a sample

Kwon M., Park Y., Lee J-H., Lee S-Y, Kim Y.T., Lee J-H., Lee S-Y, Luminescent MD, LLC, US

Using intra chemiluminescent resonance energy transfer (CRET) between DNA aptamer and fluorescein and physical property of graphene sheet, cost-effective and simple biosensor was developed for the rapid quantification of Hg2+ in a sample. The limit [...]

Graphene-Based Nanostructures for Advanced Sensing Applications

Abdul-Wahed A., Serry M., The American University in Cairo, EG

New nanostructured Schottky junctions based on graphene/platinum grown on different substrates are fabricated and investigated. The integration of graphene layer (s) on regular M-S junctions was only possible by using an ALD grown platinum thin [...]
