	We present STM and STS results obtained for double-walled carbon nanotubes. In the case displayed here, the STS results exhibit the Van Hove singularities corresponding to semi conducting tubes for both the outer and the inner shell and a finite density of states at the Fermi level (EF) is observed for a DWNT. We associate this behavior to the presence of an intershell interaction.

	Intravenously administered multi-walled carbon nanotubes, functionalized with DTPA and radiolabeled with Indium-111, were dynamically tracked in vivo using a microSingle Photon Emission Tomography scanner. Imaging showed that nanotubes enter the systemic blood circulation and within 5 min begin to permeate through the renal glomerular filtration system into the bladder.

	A simple, flexible, and robust way of fabricating fully functional electromechanical carbon nanotube (CNT) microprobes, by transferring as-grown CNT columns onto a conductive substrate using a conductive epoxy (see figure), is shown. The CNT microprobes are approximately 500 times stronger than as-grown pillars and can perform up to 200 cycles without degradation in electrical or mechanical properties.

	A new class of devices based on a hybrid combination of two different materials, nanotubes and liquid crystals, is presented. An array of individual vertically aligned multiwall carbon nanotubes creates a Gaussian electric field profile which reorients a nematic liquid crystal. The variation in refractive index acts like a graded index optical element which can be varied electrically. Results are presented from a device fabricated with 10 m pitch micro-optical elements.

	Two-dimensional colloidal lithography is successfully applied to the fabrication of novel transparent carbon nanotube networks with controllable film resistance. The method adopted in this study produces ordered network structure with regular voids in the carbon nanotube network film, and results in transparency increases compared with random network structured films, without loss of conductivity.

	DNA-single-walled carbon nanotube (SWNT) hybrid fibers are fabricated. Partial debundling and alignment of the nanotubes reduces junction resistances leading to high conductivities. The DNA is effective, as a mechanical binder and for debundling the SWNTs, even when immersed in liquid electrolytes. Therefore, the DNA-SWNT Fibers show excellent supercapacitor behavior and superior actuation performance.

	Single-walled carbon nanotubes covalently functionalized with porphyrins present enhanced optical limiting effects. Both porphyrins and SWNTs are good candidates for optical limiting applications. The porphyrin-covalently functionalized SWNTs offer superior performance to C60, the individual SWNTs, and porphyrins because of a combined nonlinear mechanism and photoinduced electron or energy transfer between the porphyrin moiety and the SWNTs.

A continuous flexible CNT electrode with high surface area and conductivity is produced, with a stable battery capacity of 572 mAh g-1.

	Networks of single-wall carbon nanotubes (SWCNTs) are covalently functionalized with oxygen-containing groups. In lower concentration, these functional groups act as stable dopands improving the conductivity of the SWCNT material. In higher concentration however, their role as defects with a certain scattering potential becomes dominant, decreasing the conductivity of the CNT material. These effects lead to a trade-off in the number of functional groups which has been investigated using time-dependent sonochemistry.

	Fault-tolerant actuators. Single-walled carbon nanotubes were studied as new compliant electrodes for dielectric elastomers. The spray-coated SWNT electrodes drive electromechanical strains greater than 200 %. When a fault is present due to pin puncture or internal defect in the elastomer films, dielectric breakdown causes localized self-clearing of the SWNT electrodes and isolation of the fault. The increased fault tolerance may enhance the actuation reliability of dielectric elastomers actuators.

	Hybrids of pyrene/CdSe-single-walled carbon nanotubes (SWNTs) are fabricated by self-assembling surface-functionalized pyrene/CdSe nanoparticles onto CVD-grown SWNTs. Light- induced charge transfer from the nanoparticles to the nanotubes is determined from the threshold voltage shift of a SWNT field-effect transistor, yielding a maximum value of 2.2 electrons per pyrene/CdSe nanoparticle.
