Observation of Early to Full Covering Stages of Ethylene-based CVD of Graphene

Celebi K., Choi J.W., Cole M.T., Altun A.O., Teo K.B.K., Park H.G., ETH Zürich, CH

Scalable growth of graphene has been demonstrated by chemical vapour deposition (CVD) using copper-based catalyst and ethylene precursor. Here, we present our ethylene-based CVD synthesis method of graphene along with our observation of early and [...]

Graphene –modified Carbon Paste Electrode for Cadmium and Lead Monitoring with Flow based System

Chailapakul O., Chuanuwatanakul S., Wonsawat W., Chulalongkorn University, TH

We successfully developed the Bi-GCPE electrode for the determination of Cd2+ and Pb2+ in real sample such as sea bass fish tissue and undulated surf clams tissue by square wave anodic stripping voltammetry. The detection [...]

Characterisation of Graphene in Liquid and Gaseous Environment with Quartz Crystal Microbalance for Applications in Real-Life Energy Storage Devices

Mazzocco R., Robinson B., Kolosov O., Lancaster University, UK

Graphene is a flat monolayer of carbon atoms whose extraordinary properties are to revolutionize the performance of many technological applications. Unfortunately there is very little understanding of how the properties of graphene change in its [...]

Generation and Evaliation of Graphene Depends on the Electron Irradiation Applied to the Fullerene

Matsukawa S., Kubota H., Kumamoto University, JP

Graphene is a flat monolayer of carbon atoms tightly packed into a two-dimensional (2D) honeycomb lattice, and is a basic building block for graphitic materials of all other dimensionalities. Electrons of graphene behave as Dirac [...]

Tunneling Negative Differential Resistance in Flexible Silicone Graphite Composites

Littlejohn S.D., Nogaret A., Crampin S., University of Bath, UK

Developing flexible electronic materials with the ability to amplify signals is a major challenge for bioelectronics. The next step in developing an active nervous system calls for a flexible electronic material that produces a signal [...]

Engineered Piezoelectricity in Graphene

Ong M.T., Reed E.J., Stanford University, US

We discover that piezoelectric effects can be engineered into nonpiezoelectric graphene through the selective surface adsorption of atoms. Our calculations show that doping a single sheet of graphene with atoms on one side results in [...]

Dispersion of chemically-modified graphene and its applications

Han J.T., Kim J-S, Kim S-H, Kim J-S, Kim S-H, Jeong H.J., Jeong S.Y., Jeong H.J., Jeong S.Y., Lee G.W., Korea Electrotechnology Research Institute, KR

In this study, we present straightforward methods to produce large-area GO sheets with fewer defects on the basal plane and for addressing the problems associated with dispersing reduced GO nanosheets in organic solvents for applications. [...]

Flexible Graphene Transistors via Printing Transfer

Chang T.-C., Suh H.-S., Mikael S., Seo J.-H., Nealey P.F., Ma Z., University of Wisconsin-Madison, US

Graphene is an atomic layer material with the characteristics of high mobility, high mechanical strength, transparency and low injection energy barrier with different work function metals. Good transparent electrodes and flexible graphene-based large scale touch [...]

Adhesion and dynamic nanotribology of graphene in polar and non-polar liquid environments studied with ultrasonic force microscopy

Robinson B.J., Kolosov O.V., Lancaster University, UK

We report the characterisation of exfoliated few layer graphene (FLG) flakes using a range of scanning probe techniques. We have examined the nanoscale mechanical and interfacial properties of FLG and its substrate material, SiO2, in [...]
