A novel single electron pump based on individual molecules (a single wall carbon nanotube) is discussed in terms of the hybrid superconducting-normal conducting pumping principle. A concept demonstration device has been built based on a carbon nanotube contacted by Nb-Ti leads. Charge current quantization is achieved through rf modulation of the back gate voltage. The device is able to transfer...

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...

We investigate the viscoelastic properties of an associating rigid rod network: aqueous suspensions of surfactant stabilized single wall carbon nanotubes (SWNTs). The SWNT suspensions exhibit a rigidity percolation transition with an onset of solidlike elasticity at a volume fraction of 0.0026; the percolation exponent is 2.3+/-0.1. At large strain, the solidlike samples show volume fraction de...

Single wall carbon nanotubes (SWCNTs) are coated with polyvinylpyrrolidone-iodine (povidone-iodine or PVPI) in water. This solution of SWCNTand PVPI is deposited as a composite film, composed of individual and bundled SWCNTs with a PVPI coating. This material acts as a conductive nanotextured bandage with high flexibility and self contained slow-release antiseptic iodine. Antibacterial properti...

The overall aim of this study is to calculate some water properties in the single wall carbon naotubes (SWCNT) and compare them to the bulk water properties to investigate the deviation of water properties inside the SWCNT from those in the bulk. Here some physical and transport properties of water molecules in the single wall carbon nanotube were reported by performing molecular dynamics (MD) ...

In this series of two papers, the humidity sensing a carbon nanotube’s (CNTs) network-based material is studied through quartz crystal microbalance (QCM) sensors. To aim, quartzes functionalized with different amounts were realized, exposed to levels, and characterized. first paper, theoretical framework presented, whereas second one presents experimental study. This paper discusses at water ad...

We demonstrate an optically active nanotube-hybrid material by functionalizing single-wall nanotubes with an azo-based chromophore. Upon UV illumination, the conjugated chromophore undergoes a cis-trans isomerization leading to a charge redistribution near the nanotube. This charge redistribution changes the local electrostatic environment, shifting the threshold voltage and increasing the cond...
