“…3; Supplementary Figs S8, S9) to further determine the different chiralities of SWNTs dispersed with rr-P3DDT, and compared it with SWNTs dispersed with sodium dodecyl sulphate (SDS; which has been previously reported to not show any selective sorting) 42 . As the PLE data indicate in Figure 3, the dominant SWNTs dispersed with rr-P3DDT were (12,1), (10,5), (8,6), (9,4) and (9,5). On the other hand, SDS/water dispersed a wide variety of SWNTs (Supplementary Figs S8, S9).…”

Selective dispersion of high purity semiconducting single-walled carbon nanotubes with regioregular poly(3-alkylthiophene)s

Conjugated polymers, such as polyfluorene and poly(phenylene vinylene), have been used to selectively disperse semiconducting single-walled carbon nanotubes (sc-sWnTs), but these polymers have limited applications in transistors and solar cells. Regioregular poly(3-alkylthiophene)s (rr-P3ATs) are the most widely used materials for organic electronics and have been observed to wrap around sWnTs. However, no sorting of sc-sWnTs has been achieved before. Here we report the application of rr-P3ATs to sort sc-sWnTs. Through rational selection of polymers, solvent and temperature, we achieved highly selective dispersion of sc-sWnTs. our approach enables direct film preparation after a simple centrifugation step. using the sorted sc-sWnTs, we fabricate high-performance sWnT network transistors with observed charge-carrier mobility as high as 12 cm 2 V − 1 s − 1 and on/off ratio of > 10 6 . our method offers a facile and a scalable route for separating sc-sWnTs and fabrication of electronic devices.

Developments in Nanostructured Cathode Materials for High‐Performance Lithium‐Ion Batteries

2008

View full text Add to dashboard Cite

Nanostructured materials lie at the heart of fundamental advances in efficient energy storage and/or conversion, in which surface processes and transport kinetics play determining roles. This Review describes some recent developments in the synthesis and characterization of nanostructured cathode materials, including lithium transition metal oxides, vanadium oxides, manganese oxides, lithium phosphates, and various nanostructured composites. The major goal of this Review is to highlight some new progress in using these nanostructured materials as cathodes to develop lithium batteries with high energy density, high rate capability, and excellent cycling stability resulting from their huge surface area, short distance for mass and charge transport, and freedom for volume change in nanostructured materials.

“…Additionally, it has been experimentally found that electrical resistance of carbon nanotubes is sensitive to the adsorption of gaseous molecules such as those released on burning of fossil fuels. 23,24 It was concluded that resistance decreases when oxidizing gas molecules adsorb on the surface, whereas adsorption of reducing gas molecules results in increasing it. These results, together with new experimental techniques, which allow controlled synthesis of monodisperse single-chirality SWCNT distributions, 25 make carbon nanotubes suitable for the development of innovative gas sensor technologies.…”

Adsorption of flue gases by single-wall carbon nanotubes (SWCNT) has been studied by means of Monte Carlo simulations. The flue gas is modeled as a ternary mixture of N 2 , CO 2 , and O 2 , emulating realistic compositions of the emissions from power plants. The adsorbed flue gas is in equilibrium with a bulk gas characterized by temperature T, pressure p, and mixture composition. We have considered different SWCNTs with different chiralities and diameters in a range between 7 and 20 Å. Our results show that the CO 2 adsorption properties depend mainly on the bulk flue gas thermodynamic conditions and the SWCNT diameter. Narrow SWCNTs with diameter around 7 Å show high CO 2 adsorption capacity and selectivity, but they decrease abruptly as the SWCNT diameter is increased. For wide SWCNT, CO 2 adsorption capacity and selectivity, much smaller in value than for the narrow case, decrease mildly with the SWCNT diameter. In the intermediate range of SWCNT diameters, the CO 2 adsorption properties may show a peculiar behavior, which depend strongly on the bulk flue gas conditions. Thus, for high bulk CO 2 concentrations and low temperatures, the CO 2 adsorption capacity remains high in a wide range of SWCNT diameters, although the corresponding selectivity is moderate. We correlate these findings with the microscopic structure of the adsorbed gas inside the SWCNTs. Published by AIP Publishing. [http://dx
