Bi-Layer Graphene Nanoribbon Memory with Graphene Nanoflake Shuttle
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
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
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
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
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 [...]
