The behaviour of support electrodes modified with randomly dispersed single-wall carbon nanotube meshes containing adsorbed glucose oxidase with respect to amperometric glucose detection at a low potential is demonstrated.

We report the unambiguous detection of a sequence of Hepatitis C Virus (HCV) at concentrations down to the fractional pM range using Single Wall Carbon Nanotube (SWNT) Field Effect Transistor (FET) devices functionalized with Peptide Nucleic Acid (PNA).

Pyrene mediated noncovalent attachment of a chlorophyll derivative, pyro-pheophorbide a, to a soluble single wall carbon nanotube is reported and the resultant CD, UV-Vis absorbance, fluorescence and 1H NMR spectra are discussed.

In this study, the focus is on exploring remarkable world of aircraft structures with aim creating a material that pushes boundaries and garners global attention. The successful formulation composite investigated by skillfully manipulating weight quantity ratios. To achieve desired outcome, different ratios multi-walled carbon nanotubes (MWNTs), specifically 8g 16g, are combined. Furthermore, t...

This work is focused on synthesis of SiO2- CNT hybrides via sol-gel method. Homogeneous distribution of carbon nanotubes within silicon matrix was obtained by mixing the functionalized carbon nanotube (CNTCOOH) with active silicic acid followed by titration to the solution of sodium silicate (Na2SiO3) under the average temperature condition of 80?C. Different ratios of multi-walled carbon nanot...

This experimental study aimed to compare the adsorption of oleic acid (fatty acid) by two adsorbent; activated carbon and carbon nanotube by use of Uv-Vis spectrophotometer Jenway 6505 model. In this study, five different concentrations of oleic acid in the range of 282.47ppm to 847.41ppm were used. In all conducted experiments, the values of adsorbents, exposure time, temperature, and pH were ...

Multiscale simulation approaches are needed in order to address scientific and technological questions in the rapidly developing field of carbon nanotube electronics. In this paper, we describe an effort underway to develop a comprehensive capability for multiscale simulation of carbon nanotube electronics. We focus in this paper on one element of that hierarchy, the simulation of ballistic CNT...

We have reproducibly contacted gated single wall carbon nanotubes (SWCNT) to su-perconducting leads based on niobium. The devices are identified to belong to two transparency regimes: The Coulomb blockade and the Kondo regime. Clear signature of the superconducting leads is observed in both regimes and in the Kondo regime a narrow zero bias peak interpreted as a proximity induced supercurrent p...

Density-functional theory is used to investigate hydrogen physisorption on a graphene layer and on single wall carbon nanotubes. Both external and internal adsorption sites of 9, 0 and 10, 0 carbon nanotubes have been studied with the hydrogen molecular axis oriented parallel or perpendicular to the nanotube wall. A range of hydrogen molecule binding sites has been examined and it is found that...
