Maskless Lithography of Nanometer-Scale Circuit Structures in Supported, Single-Layer Graphene Using Helium Ion Microscopy

Rondinone A., Iberi V., Matola B., Linn A., Joy D., Oak Ridge National Laboratory, US

Here we will discuss the utility of scanning helium ion lithography for fabricating conducting graphene structures that are supported directly by silicon oxide. The lithography is performed in a single step, dry, using high-resolution He- [...]

Application of chemiluminescent resonance energy transfer and graphene sheet for the rapid quantification of mercury in a sample

Kwon M., Park Y., Lee J-H., Lee S-Y, Kim Y.T., Lee J-H., Lee S-Y, Luminescent MD, LLC, US

Using intra chemiluminescent resonance energy transfer (CRET) between DNA aptamer and fluorescein and physical property of graphene sheet, cost-effective and simple biosensor was developed for the rapid quantification of Hg2+ in a sample. The limit [...]

Graphene-Based Nanostructures for Advanced Sensing Applications

Abdul-Wahed A., Serry M., The American University in Cairo, EG

New nanostructured Schottky junctions based on graphene/platinum grown on different substrates are fabricated and investigated. The integration of graphene layer (s) on regular M-S junctions was only possible by using an ALD grown platinum thin [...]

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 [...]
