Turning carbon nanotubes from exceptional heat conductors into insulators.
Thermal conductivity (kappa) of isolated carbon nanotubes (CNTs) is higher than the kappa of diamond; however, in this Letter we show that the kappa of a packed bed of three-dimensional random networks of single and multiwall CNTs is smaller than that of thermally insulating amorphous polymers. The thermoelectric power (Sigma) of the random network of CNTs was also measured. The Sigma of a sing...
متن کاملTurning carbon dioxide into fuel.
Our present dependence on fossil fuels means that, as our demand for energy inevitably increases, so do emissions of greenhouse gases, most notably carbon dioxide (CO2). To avoid the obvious consequences on climate change, the concentration of such greenhouse gases in the atmosphere must be stabilized. But, as populations grow and economies develop, future demands now ensure that energy will be...
متن کاملOne Dimensional Transport in Carbon Nanotubes
The devices used in these studies consist of individual single-walled nanotubes (SWNTs) or SWNT ropes[9] to which electrical contacts are made, as shown in Figure 1. The nanotubes are deposited onto 2302 grown on top of a degenerately doped Si wafer. Atomic force microscope (AFM) imaging reveals that the diameters of the deposited objects vary between 1 and 10 nm, with the smallest ones being s...
متن کاملTheoretical insights into the encapsulation of anticancer Oxaliplatin drug into single walled carbon nanotubes
The present work was an attempt to evaluate the potentialities of using SWCNTs as nanovectors for drug delivery of anticancer drug Oxaliplatin. First-principles van der Waals density functional (vdW-DF) calculations are used to investigate the incorporation of oxaliplatin inside the typical semiconducting and metallic single wall carbon nanotubes with various diameters (SWCNTs). Adsorption ener...
متن کاملChromophore Ordering by Confinement into Carbon Nanotubes
We report an experimental study on the confinement of oligothiophene derivatives into single-walled carbon nanotubes over a large range of diameter (from 0.68 to 1.93 nm). We evidence by means of Raman spectroscopy and transmission electron microscopy that the supramolecular organizations of the confined oligothiophenes depend on the nanocontainer size. The Raman Radial Breathing Mode frequency...
