Bi-Layer Graphene Nanoribbon Memory with Graphene Nanoflake Shuttle

Kwon O-K., Kang J-W, Lee J-H., Semyung University, KR

We investigated the dynamic properties of graphene-nanoribbon (GNR) memory encapsulating graphene-nanoflake (GNF) shuttle in the potential to be applicable as a non-volatile random access memory via molecular dynamics simulations. This work explicitly demonstrates that the [...]

Comparisons of electrochemical sensors for heavy metals detection based on filter paper and transparency film substrate

Ruecha N., Rodthongkum N., Cate D.M., Chailapakul O., Henry C.S., Chulalongkorn Uiversity, TH

Electrochemical sensors based on filter paper and transparency film substrates have been prepared using screen-printing method for the detection of the heavy metals Pb2+, Cd2+, and Zn2+. The electrochemical characteristics of these electrodes were analyzed [...]

Graphene/polyaniline nanocomposite modified electrode for biosensors

Chailapakul O., Yukirdb J., Rodthongkum N., Rangkupan R., Pisitkun T., Chulalongkorn University, TH

A novel system based on graphene/polyaniline nanocomposite modified electrode was successfully developed for sensitive and specific determination of NGAL protein biomarker. Then, the optimum conditions were applied for the detection of NGAL in real biological [...]

Graphene-Loaded Nanofiber-Modified Electrode: A Novel and Sensitive Electrochemical Detection System

Rodthongkum N., Ruecha N., Promphet N., Rangkupan R., Vachet R.W., Chailapakul O., Metallurgy and Materials Science Research Institute, Chulalongkorn University, TH

This work aims to develop a novel electrode based on graphene loaded nanofibers for sensitive electrochemical detection of biomolecules (i.e. dopamine) and heavy metals. The very low limit of detection are obtained for both dopamine [...]

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 [...]

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 [...]
