Architecturing Carbon Nanotube-based Flexible Solid State Supercapacitor

Adu K, Ma D., Radall C., Rajagopalan R., Armstrong P., Stigers S., The Pennsylvania State University, US

We report a novel post synthesis self-assembly technique that transforms the trillion of carbon nanotubes into a robust, flexible and binder-free membrane and demonstrate its application in designing flexible bipolar solid state supercapacitor with high [...]

Voltammetric and Impedance studies of Phenols and Its Derivatives at Carbon Nanotubes/Prussian Blue Films Platinum Modified Electrode

Adekunle A.S., Arotiba O.A., Agboola B.O., Maxakato N.W., Mamba B.B., Ebenso E.E., North-West University, ZA

Phenols and the chlorinated and alkylated derivatives are classified as priority pollutants due to the health risk associated with their toxicity. Due to their constant presence in industrial waste and consequently their carcinogenic risk for [...]

Understanding Ru/CNT interactions: A rational design of Ru nanocatalysts

Machado B.F., Oubenali M., Axet M.R., Nguyen T.T., Tunckol M., Girleanu M., Ersen O., Gerber I.C., Serp P., Laboratory of Coordination Chemistry, FR

We report a detailed study on the nature of the ruthenium–carbon nanotube (Ru/CNT) interface in catalysts prepared from neutral Ru(0) organometallic precursors. Experimental data combined with density functional theory calculations allowed to conclude that both [...]

Role of Caveolin-1 in Carbon Nanotube-Induced Stem-Like Cells and Tumorigenesis

Luanpitpong S., Wang L., Castranova V., Stueckle T., Rojanasakul Y., West Virginia University, US

Carbon nanotubes (CNT) hold great promise to create new and better products, but their long-term adverse health effects are a major concern. The objective of this study was to develop an in vitro model for [...]

Effect of carbon nanotubes on plant growth and gas exchange using Arabidopsis thaliana

Voleti R., Missouri State University, US

There has been increasing interest in the biological and biomedical applications of carbon nanotube. We addressed the novel question: Are pure CNTs produced for distribution to manufacturers “toxic” to plants through their effects on physiological [...]

Multi-method analysis of multiwall carbon nanotube polymer nanocomposite after photodegradation

Petersen E.J., Lam T., Gorham J., Scott K., Long C., Sharma R., Sung L.P., Liddle J.A., Nguyen T., National Institute of Standards and Technology, US

Nanomaterials can be used as nanofillers to enhance the properties of polymeric materials. However, the effect of weathering on nanocomposites and the potential for nanomaterial release is not yet well known. This stems partly from [...]

Record resistivity for in-situ grown horizontal carbon nanotubes interconnects

Dijon J., Ramos R., Fournier A., Fournier H., Le Poche H., Fournier A., Fournier H., Okuno H., Simonato J-P, CEA-Liten, FR

Carbon in the form of nanotubes (CNTs) and graphene is the only known material that can replace copper in integrated circuits to carry the high current densities associated with advanced interconnects. Its implementation is however [...]

Carbon Nanotube Matrices for implantable Biofuel Cell design

Holzinger M., Le Goff A., Cosnier S., CNRS - University of Grenoble, FR

Glucose biofuel cells are promising candidates to supply implanted electronic devices by converting the chemical energy of glucose, present in body fluids, into electric power. Before such biofuel cells can become realistic alternatives compared to [...]

Thermomechanical Properties of Epoxy Resin / Carbon Nanotubes / Clay Nanocomposites

Zois H., Patargia E., Kanapitsas A., Stimoniaris A.Z., Delides C.G., Technological Educational Institute Stereas Elladas, GR

The main aim of the present work is to investigate the thermomechanical properties and thermal stability of nanocomposite materials based on epoxy resin matrix reinforced with amine-modified multi-walled carbon nanotubes and clay nanoparticles (Closite 30). [...]

Effect of Layer Multiplying Extrusion on the Morphology and Properties of PS/CNT Nanocomposites

Jian R., Barry C., Mead J., University of Massachusetts-Lowell, US

Multilayer coextrusion has been used to produce extruded films having up to several thousand alternating layers with individual layer thicknesses ranging from several micrometers to only a few nanometers. In this work, the multilayer coextrusion [...]
