Copper/CNT composite materials with enhance mechanical and termal properties

Silvain J.F., Vallet G.M., Dunand M., ICMCB-CNRS, FR

With their huge mechanical, thermal and electrical properties, carbon nanotubes are good candidates as reinforcements in material composites. However, such materials are not easy to elaborate and several problems occurred such as the dispersion of [...]

Cross-Linked Single-Walled Carbon Nanotube Buckypapers and their Composites

Guan J., Jakubinek M.B., Ashrafi B., Johnson M., White M.A., Simard B., National Research Council Canada, CA

Single-walled carbon nanotubes (SWCNT) covalently modified with OH functional groups were assembled into buckypapers through solvent dispersion and vacuum filtration. These SWCNT-OH buckypapers were subsequently crosslinked by wetting with bifunctional linkers followed by hot compression, [...]

SWCNT vs MWCNT and Nanofibers. Applications in lithium-ion batteries and transparent conductive films

Predtechenskiy M., Bezrodny A., Bobrenok O., Kochnev A., Kosolapov A., Krechetova N., Saik V., OCSiAl LLC (OCSiAl Group), US

Among the most promising applications of carbon nanotubes are their use as additives in electrode material of lithium-ion batteries and in the production of flexible transparent conductive films. Experiments with various types of cathode materials [...]

Advanced Aerospace Applications for Carbon Nanotube Materials

Schauer M.W., Nanocomp Technologies, Inc., US

The use of floating catalyst chemical vapor deposition to make carbon nanotube (CNT) materials for aerospace structures overcomes the need for dispersants, and allows for products that consist mostly of nanotubes. CNT-based material is currently [...]

Raman Spectroscopic Characterization of Carbon Nanotubes & Tungsten Oxide of Relevance to Energy Storage and Gas Sensing Applications

Misra P., Casimir D., Garcia-Sanchez R., Baliga S., Howard University, US

The characterization of graphitic and metal oxide nanomaterials through the use of Resonant Raman Spectroscopy at multiple laser excitations is the primary aim of this research. Raman spectroscopic techniques can help characterize the vibrational phonon [...]

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 [...]

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 [...]

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 [...]

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 [...]
