Maskless Lithography of Nanometer-Scale Circuit Structures in Supported, Single-Layer Graphene Using Helium Ion Microscopy
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- [...]
A reliable supply platform for Graphene and other 2D Materials
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 [...]
Synthesis of Reduced Graphene Oxide Films using Atmospheric Plasma and Furnace Annealing
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 [...]
Preparation of electrical conductive polymer/graphite oxide composites through the functionalization of graphite oxide sheets
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 [...]
Effect of the Kind of Carbon-Based Nanofiller on the Electrical Conductivity and Rheological Melt Behavior of Polypropylene Composites
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 [...]
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, [...]
Electrochemical and textural characterization of RuO2-SnO2-graphene under co-precipitation / hydrothermal conditions
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 [...]
Hexa-peri-hexabenzocoronene-porphyrinoids as models for functional graphenes in the development of newer materials
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 [...]
Manganese Oxide/Carbon Nanofibers-Embedded Graphene Sheets for Capacitors
We report the fabrication of a ternary nanoarchitecture consisting of manganese oxide (MnO), carbon nanofibers (CNFs), and reduced graphene oxide sheets and their application to supercapacitor electrodes. MnO nanoclusters-decorated CNFs (MCNFs) with diameters of about [...]
Modeling of spontaneous phase separation in nanomaterials and confined systems with electron correlations
The modeled of many body physics and possible spontaneous phase separation instabilities in various two-dimensional square and honeycomb structures (generated by periodically repeated Betts lattices) provide an ideal playground for understanding of various competing phases [...]
Investigation of interaction between graphene and steel using Raman Spectroscopy
The purpose of this study is to understand interaction between graphene and sheet steel by the use of Raman Spectroscopy. First of all, the graphene was put on the polished steel. Secondly, it was inspected [...]
