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, [...]

Pulsed Laser Annealing of Nanocarbon Materials

Vander Wal R.L., Gaddam C.K., Penn State University, US

Pulsed laser annealing of nanocarbons, with focus upon soot was performed using a Nd:YAG laser operating at 1064 nm and laser fluence of 250 mJ/cm2. A gated intensified CCD captured the spectra of the material [...]

Effect of length and radius of singlewall carbon nanotube on its mechanical properties

Alzubi F.G., Cosby R., Kuwait Institute for Scientific Research, KW

A first principles atomistic calculations and analysis of Young’s modulus for short arm chair carbon nanotubes with different lengths and radii is]]are reported. The atomic forces and total energies were computed for the carbon nanotubes [...]

CNT reinforced Aluminum composite

Moon S., Lee D., Jung S., Applied Carbon Nano Technology Co Ltd, KR

Carbon nano tube(CNT) is known as a pioneer material for new century because of its excellent physico-chemical properties. Despite the good properties of CNT itself, CNT's application is restricted by its size problem. We have [...]

Carbon NanoDots for Selective Optical Cation Detection

Buiculescu R., Fouskaki M., Chaniotakis N.A., University of Crete, GR

In the present work, custom designed and synthesized carbon nanodots (C-dots) with cation selective functional organic ligands (carboxyl or amino) are used for the optical detection of cations. The ligands on the surface are able [...]

Single Wall Carbon Nanotube Inhibition of DNA Damage

Nelson B.C., NIST, US

Carbon nanotubes (CNTs) are remarkable materials in terms of their enhanced thermal and electrical conductivities, tensile strengths and mechanical properties. However, our understanding of the potential environmental, health and safety risks of these novel nanomaterials [...]

Silver coated carbon nanotubes regulate virulence gene expression in Salmonella Typhimurium

Chaudhari A.A., Singh S.R., Pillai S., Alabama State University, US

Silver coated carbon nanotubes (AgCNTs) have several biomedical applications and their antibacterial activity against several multi drug resistant pathogens is well documented. However, the exact molecular mechanism for their antibacterial activity is yet to be [...]

Layer-on-layer Assembly of Macroscopic 2D and 3D Carbon Nanomaterial Architectures

Patel S.C., Lalwani G., Alam O., Grover K., Qin Y-X, Sitharaman B., Stony Brook University, US

Although carbon nanomaterials are often labeled as the future replacement for silicon in electronics and a new generation of robust materials, there are major shortcomings in the assembly of carbon nanomaterials into higher order structures. [...]

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 [...]
