We discuss the Luttinger Liquid behaviour of Large Radius Carbon Nanotube e.g. the Multi Wall ones (MWNT), under the action of a transverse magnetic field B. Our results imply a reduction with B in the value of the bulk critical exponent, αbulk, for the tunneling density of states, which is in agreement with that observed in transport experiments. Then, the problem of the transport through a Qu...

Multiwalled carbon nanotube (MWNT)/cellulose composite nanofibers have been prepared by electrospinning a MWNT/cellulose acetate blend solution followed by deacetylation. These composite nanofibers were then used as precursors for carbon nanofibers (CNFs). The effect of nanotubes on the stabilization of the precursor and microstructure of the resultant CNFs were investigated using thermogravime...

An electrochemical method has been developed for the determination of tricresyl phosphate (TCP) in aqueous media and air. Although TCP is not an electroactive species, conversion of TCP by acid hydrolysis to cresol enables electrochemical detection techniques to be exploited. Amperometric detection was performed using glassy carbon electrode (GC), glassy carbon electrode covered with multiwall ...

Aqueous suspensions of multi-wall carbon nanotubes (MWNTs) in dilute H2SO4 were sprayed onto both sides of a Nafion membrane and dried to fabricate flexible solid-state supercapacitors. A single cell with MWNT-only electrodes had a capacitance of 57 F g(-1) per electrode at 2 mV s(-1) and 44 F g(-1) at 150 mV s(-1) but with low H(+) mobility. Cells with MWNT + ionomer hybrid electrodes showed h...

We have created a tunable mechanical nanoscale resonator with potential applications in precise mass, force, position, and frequency measurement. The device consists of a specially prepared multiwalled carbon nanotube (MWNT) suspended between a metal electrode and a mobile, piezo-controlled contact. By exploiting the unique telescoping ability of MWNTs, we controllably slide an inner nanotube c...
